Answer

Explanation:

Step1: Recall atomic number concept for He

The atomic number of Helium (He) is 2. In a neutral atom, the number of protons equals the atomic number. So for a He - atom with mass number 4, the number of protons in the nucleus is 2.

Step2: Recall atomic number and electron - shell rules for Li

The atomic number of Lithium (Li) is 3. In a neutral atom, the number of electrons equals the number of protons. The electron - shell filling order is 2 in the first shell and the remaining in the second shell. So for Li with atomic number 3, the number of electrons in the outermost orbital is 1.

Step3: Recall mass - number formula for N

The mass number (A) is the sum of protons (p) and neutrons (n), i.e., $A=p + n$. The atomic number of Nitrogen (N) is 7. Given mass number $A = 14$, then $n=A - p=14 - 7 = 7$.

Step4: Recall atomic number and electron - shell rules for B

The atomic number of Boron (B) is 5. In a neutral atom, the number of electrons is 5. The first shell can hold 2 electrons, and the remaining $5 - 2=3$ electrons go to the second shell.
