Question

An element X belongs to 6thA
group the most important ion of this element is
1)x6+. 2)x1- 3)x2- 4)x3-
Answer with explanation ​

Answer 1

$\LARGE\underline{\purple{\sf{Required\:answer:-}}}$

We are given that Some Element 'X' belongs to VI A group.In a geoup the valency of the element and and the group number of the element is same. This mean number of electrons in the valence shelll (or) Valence electrons in the atom is equal to the group number.

So , This Element 'X' has 6 valence electrons . It needs 2 more electrons to acquire stable electronic configuration (or) octet. This element gains 2 electrons . When electrons are gained the atom acquires negative charge on it and when electrons are lost it acquires positive charge.

This element 'X' gained 2 electrons . So , The ion of this element is X²⁻

Hence , Option(3) is the required answer.
