Since it has 6 valence electrons. So, it will belong to group 6.
The valency of element E is 2 because it requires 2 more electrons to complete its stable gas configuration.

The element X belongs to the 16th group and 3rd period of the modern periodic table. The no. of electrons in the valence shell + 10 indicates the group and the no. of shells indicate the period.
The valency is 2 since it needs 2 more electrons to attain noble gas configuration.
Hope it helps you.
If it did mark it as the brainiest;-)
