Question

The successive ionisation potential of an element m are 176 346 and 1850 kcal formula of the sulphate of m is

Answer 1

Answer:

The chemical formula of its sulphate is MSO₄.

Explanation:

From the given ionization potential values, we can identify the fact that the 3rd potential is comparatively very high, i.e., requires a lot of energy to remove its 3rd electron.

From this, we can conclude that the element becomes stable in its +2 state, meaning that after losing 2 of its electrons, it attains a noble gas configuration.

Thus, we can understand that its valency is +2, i.e., element M is ready to combine in its +2 state (M2+) - $M^2^+ + SO_4^2^- \rightarrow MSO_4$

Thus, the chemical formula of its sulphate is MSO₄.
