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.
