Question

Generally speaking, how can you determine the charge of an ion formed by a representative element?

• A. The charge of the ion formed is related to the element's group number.
• B. The charge of the ion is related to the element's period number.
• C. An ion's charge is always 1/2 the atomic number.
• D. The charge of the ion is the number of valence electrons minus the number of core electrons.

Answer 1

The correct option is A The charge of the ion formed is related to the element's group number.

Representative elements : s-block and p-block elements are representative elements.
The charge of the ion formed is related to the element's group number.
For example:
As Group-1 elements have +1 charge.
As Group-2 elements have +2 charge.
