Explanation:
<em>Did it on Edgenuity and got it correct (2020).</em>
Answer:
He has two protons
Li electron has one electron in its outermost orbital.
Number of neutrons of nitrogen = seven neutrons
The second shell of boron: 3 electrons.
Explanation:
An atom is composed of electrons, protons and neutrons. The number of neutrons is determined by subtraction of the atomic number from the mass number.
The electronic configuration is already known for each of atoms in these questions according to standard tables.
