| Is aluminium foil is safe for food wrapping? |

Food wrapped in aluminum foil is not likely to pick up much aluminum unless the foods are acidic (think tomato sauce or a salad with a vinegar dressing). However, cooking in aluminum foil will increase the amount of the metal leached into the food.
It’s not clear whether such levels of leached aluminum are harmful. Aluminum is found naturally in a lot of foods (it is one of the earth’s most abundant elements) as well as in some antacids. The body does a good job excreting such levels of aluminum.
There is some speculation that aluminum may be involved in Alzheimer's disease or inflammatory bowel disease, but the evidence is contradictory. Most toxicologists consider the usual low levels of aluminum to be safe (see, for example, Systematic review of potential health risks posed by pharmaceutical, occupational and consumer exposures to metallic and nanoscale aluminum, alumin... - PubMed - NCBI)
That said cooking an acidic sauce in aluminum or storing acidic foods in aluminum containers may contribute off-flavors and probably should be avoided. But other uses are probably fine.

Cooking in aluminium and its impact has not been researched enough or thoroughly to establish any direct relationship or impact. Pressure cookers and normal cooking vessels like pans and pots have been made in aluminium for over 10 decades Aluminium is is the most commonly used commercial cooking utensil by far. Reputed companies and many arbiters of food science have no clear answer or studies. All we hear from these discussions is just anecdotal evidence and hear-say. Same is true for copper and brass vessels and also stainless steel. Just by seeing turmeric stains on the aluminium vessel does not mean it is harmful for health. Even the normal fresh food and fruits contain aluminium from the soil absorption. Levels of aluminium in the body vary and some data seems to indicate that poor functioning kidneys are not able to excrete the aluminium effectively. This does not mean that aluminium is bad for the kidney. Same is the case with Alzheimer - brain tissue seems to indicate presence of aluminium - but that does not immediately mean aluminium vessels causes Alzheimer. Bottom line is probably this: not enough data, not clear documentation, too anecdotal and going forward needs a more thorough review and research. In the meanwhile - what can we really do - mix and match the use of metal vessels and use good quality goods. And dont scare people with anecdotal evidence gathered from here and there

Atomic mass of any element ( except Hydrogen whose atomic is 1u ) is mostly (roughly) double of its atomic number ( for elements with lower atomic numbers as I have seen ).
Atomic number of Al is 13
and, its atomic mass is (roughly its double + 1 i.e. ) 27 u

May I correct a bit in the question? Elements have symbols Aluminum Chloride is a chemical compound Hence it has no symbol but a chemical formula
Chemical formula for aluminium Chloride is
AlCl 3
REASON—-
Electronic configuration of Aluminium atom is 2,8,3
So there 3 electrons in its outermost orbit
Electronic configuration of Chlorine atom
is 2,8,7
So there are 7 electrons in its outermost orbit Each of them has a tendancy to have 8 electrons (octet) in its outermost orbit Hence they give or take electrons
Here aluminum is the donor Chlorine is the
acceptor Aluminum atom has 3 electrons to give and a Chlorine atom can accept only a single electron,Hence three Chlorine atoms are required to accept three electrons given by the aluminum atom Therefore three Chlorine atoms react with a single aluminum atom Hence the chemical formula of aluminium Chloride is AlCl3
The answer is given in detail looking at the question and that too for beginners

The battle lines have been drawn now that Ford’s ground-breaking F-150 – made with aluminum – is in full production. Speculation about the spread of aluminum into other steel-dominated platforms is rampant these days. The U.S. Department of Energy has added fuel to that debate, announcing a conditional commitment for a $259 million loan to Alcoa Inc.
If finalized, the loan would support the company’s Alcoa, Tennessee, manufacturing facility. Alcoa, the largest producer of aluminum in the United States, hopes to use the facility to produce high-strength aluminum for North American automakers looking to lightweight their vehicles.
“This is good news for Alcoa and Tennessee,” said Senator Lamar Alexander. “Today, more than one-third of Tennessee manufacturing jobs are auto related, and investment in advanced manufacturing is an important part of how our state will continue to attract good-paying jobs.”

Alcoa estimates that its expanded production will create 200 permanent full-time jobs – in addition to 400 jobs at the peak of construction. The plant’s expansion will provide additional aluminum sheet manufacturing capacity intended for the U.S. automotive market.
The goal is to boost fuel economy by reducing vehicle weight, while still maintaining safety. High volume models such as the F-150, for example are using aluminum-intensive designs to do just that. Ford’s new model features weight savings of more than 700 pounds per vehicle.

| Is Aluminum More Sustainable than Steel? |

While aluminum can be easily recycled through advanced processes, steel has the advantage of being the most recycled material in the world. The recycling process of steel is simpler, too: Its ferrous property allows for easy scrapyard sorting, and all alloys of steel can be melted together and remixed to produce any alloy of steel. Aluminum, on the other hand, is costlier to recycle, requiring the different grades to be separated before melting to preserve the grades.

aluminum-bodied vehicles are safer than their steel counterparts thanks to better energy absorption, larger crush zones that fold more predictably and larger overall size.
Dr. Hall brings up an interesting counterpoint to these advantages: It’s not the material that matters so much as how you design with that material.
“You can design a safe vehicle with other materials [than steel], but it’s a combination of materials and design,” she said. “It’s absolutely, scientifically incorrect to say that aluminum, as a material, is ‘safer.’”
When I brought up the counterpoint that every aluminum-bodied vehicle on the road has a five-star safety rating, she pointed to the confounding variables that may explain why:
“All are newer, higher-end vehicles. Luxury vehicles can afford the extra engineering to get that rating, and in the case of the Ford F-150, I think it’s a very aggressive and risky move to convert a pickup to aluminum. I think they did absolutely everything they could to make sure it would work.”
So, aluminum can be as safe as steel—but at higher cost.

[font=宋体]New energy vehicles will help to achieve energy conservation and emission reduction and alleviate environmental pressures. However, at present, the batteries used in new energy vehicles cannot meet the requirements of the cruising range of vehicles. Only by reducing the weight of the whole vehicle can the cruising range be improved. Related research shows that the pure electric vehicle's overall vehicle weight is reduced by 10kg, and the driving range can be increased by 2.5km. This shows the importance of car lightweighting.[/font]
[font=宋体]The development of lightweight vehicles is inseparable from the choice of vehicle materials. Among many lightweight materials, aluminum alloy materials have obvious advantages. The density of aluminum is small, only 1/3 of steel. The aluminum alloy is used instead of steel to optimize the structure and reduce the weight of the body by more than 50%. Due to the high strength, corrosion resistance, good processing performance and high recycling efficiency of aluminum alloy, the consumption of aluminum in automobiles has increased rapidly.[/font]
[font=宋体]At present, aluminum alloys used for automobile lightweighting are 5182, 5083, 5754, 5052, 6061 alloy aluminum plates, etc., which are respectively used in different parts of the vehicle. The 5754 aluminum plate is a common alloy for automotive fuel tanks and a star product of Mingtai Aluminum. We can process 5754 aluminum plate with thickness of 0.30-600mm and width of 150-2600mm. It has medium strength, high corrosion resistance and good weldability. It has a good application effect in the field of automobile fuel tank.[/font]
