Question

Given below is the atomic structure of an atom of element ²⁴₁₂X, according to Bohr's model of the atom (where, n and p represent the number of neutrons and protons respectively).

If an element Y has two electrons in its outermost shell, what would be the nature and charge on the ion formed if both electrons are removed from the outermost shell?

Determine the valency of the following atoms: X, Y, Z, W

Write down the electron distribution of the Phosphorus atom. How many electrons are there in the M shell? (Atomic number of phosphorus is 15).
