Question

There is an element X with atomic number 16.To which group in the periodic table does this element X belong to?

• A. The element belongs to the 14th group.
• B. The element belongs to the 16th group.
• C. The element belongs to the 13th group.
• D. The element belongs to the 15th group.

Answer 1

The correct option is B The element belongs to the 16th group.

The electronic configuration of the element having atomic number 16 will be:

$1s^{2}2s^{2}2p^{6}3s^{2}3p^4$

This element is belongs to the p block.

The group number of p block element can be found by adding 10 to the total number of electrons present in s and p subshell of the outermost shell . Hence it will be placed in 16th group.
