Homework Answers
Answer is ; It become smaller in size
Explanation : As you know that Magnesium has 12 electrons and 12 protons too.
After loosing 2 electrons Mg ++ becomes a cation. But its size reduces ; because now 10 remaining electrons are pulled by 12 protons causing more attraction force toward Nucleus.

0/4 pts Question 5 Electrons exist in orbitals within an atom. Bohr's model described a single electron system well. But the energy level for orbitals change when as you add a second and more electron. In a single electron system, there are (a)_orbital(s) at the n-2 level. These n-2 orbital(s) exist at (b) sub-level(s) in the atom. In a multi-electron system, (c)_orbital(s) at the n-2 level. These n-2 orbital(s) exist at (d)sub-level(s) in the atom. Bohr was never...
