WebImgur. The energy of the electron of a monoelectronic atom depends only on which shell the electron orbits in. The energy level of the electron of a hydrogen atom is given by the following formula, where n n denotes the principal quantum number: E_n=-\frac {1312} {n^2}\text { kJ/mol}. E n = − n21312 kJ/mol. For a single electron instead of ... WebHow many valence electrons does Lithium (Li) have? Family 18 What family is Krypton (Kr) in? 3 energy levels How many energy levels does Magnesium (Mg) have? 2 valence electrons How many valence electrons does Zinc (Zn) have? The Noble Gases are NOT very reactive because they all have the max number of valence electrons they need. THEY ARE …

WebLithium will always have 3 protons, as that is what defines it as being lithium. Basically, the number of electrons and neutrons don’t do anything to define an element. The only thing that matters is the number of protons. If you have 3 protons in the nucleus, it is lithium, no matter what else you may or may not have. WebThe lithium atom is slightly different because it has three electrons. It has too many electrons for energy level K, and one electron must stay in a different energy level. The lithium atom electrons have the lowest possible energy states because two are in energy level K and the other is in L. Figure 3: The nucleus and electrons of a lithium atom. WebThe lithiumatom has a closed n=1 shell with two electrons and then one electron outside. Since the outer electron looks inward at just one net positive charge, it could be expected … ctm aulnay sous bois
