Correct Option: A
The element with atomic number 17 is Chlorine which has a valency of -1.
Hence, it needs to receive an electron or lose seven electrons to obey the octet rule which refers to the tendency of atoms to prefer to have eight electrons in the valence shell. When atoms have fewer than eight electrons, they tend to react and form more stable compounds
