Question

X2SO3 Enter the group number of X. How do I find this? Chemistry

Answer 1

Na2SO3 and H2SO3 are the possible compounds hence X belongs to group number 1.

Answer 2

Answer: The group number of X is Group 1.

Step-by-step explanation:

Groups are defined as the vertical columns in a periodic table.

We are given a chemical compound having chemical formula of
`X_2SO_3`

This is formed by the combination of X atoms and
`SO_3^(2-)` ions.

By criss-cross method, 2 atoms of X combine with 1 atom of sulfite ions.

Thus, the oxidation state of X atom is +1.

The elements belonging to Group 1 shows an oxidation state of +1.

Hence, the group number of X is Group 1.
