Im doing a study guide I have absolutely no idea how to do this.What element is created when you ADD 3 electrons to tellurium?What element is created when you REMOVE 3 electrons from silicon? What element is created when you REMOVE 3 electrons from aluminum?How did you get your answer? I have tried looking EVERYWHERE but hereI lost my college text book and need to finish this before the test tomorrow so PLEASE help
We need to know whether this is (as I suspect) dealing with nuclear reactions (not chemical reactions)Assuming I am right in thinking that these are nuclear reactions, and ignoring the number of neutrons in any particular element, we would have: (1) What element is created when you ADD 3 electrons to tellurium? n/52-Te + 3 e- → n/49-In n represents whatever atomic mass that nuclide has, and the number under the division sign is the atomic number of that element(2) What element is created when you REMOVE 3 electrons from silicon? n/14-Si - 3 e- → n/17-Cl (3) What element is created when you REMOVE 3 electrons from aluminum? n/13-Al - 3 e- → n/16-S So how did I come up with that? The gain of an electron, electron capture, results in a proton of the nucleus combining with the electron to form a neutronThe loss of that proton results in a decrease in the atomic number (the number of protons in the element) by oneSimilarly, the loss of an electron, beta decay, is from a neutron that then forms the electron (which is ejected from the nucleus) and a proton (which stays in the nucleus)This increases the number of protons in the nucleus by one and increases the atomic number by one.Other related question
