Question

The table shows the electronic configuration of four elements.

Element	Electronic configuration
W	2, 6
X	2, 8
Y	2, 8, 1
Z	2, 8, 7

Which pair of atoms will form a covalent compound?

Options

• two atoms of W

• two atoms of X

• an atom of W and an atom of X

• an atom of Y and an atom of Z

Answer 1

Two atoms of W

Explanation:

Element W has 6 valence electrons, making it a non-metal. Two atoms of W will mutually share two pairs of electrons to complete their stable octets, creating a covalent molecule (like O₂).
