Question
An element X is in the 1st group of the modern periodic table. Its ion will be represented as:
Answer: Option A
:
A
The elements in the 1st group of the periodic table have only one valence electron. Thus, they will tend to lose only one electron to gain the the nearest noble gas configuration.
So, valency of the elements in the 1st group of the modern periodic table is 1 and they will lose one electron to form unipositively charged ion, (A+).
