Answer 1

14) There are four valence electrons

15) The overall charge is + 3

16) Tin is a metalloid

17) Calcium - 20, Phosphorus - 15, Helium - 2

18) Sulfur - G aluminum - L magnesium - L

19) Neon - Nill Oxygen - 2 Potassium + 1

What is the Bohr model?

Niels Bohr developed the Bohr model, a condensed atomic model, in 1913 to explain the structure of hydrogen atoms. It was developed to address the limitations of classical physics in its attempt to explain the stability of electrons in orbit around the nucleus.

According to the model, electrons in stable orbits don't radiate and have quantized angular momentum. This idea makes the stability of atoms clear.
