Question

Show with the help of diagram of electronic configuration how the following compound are formed from the constituent atoms.
a. Sodium chloride ​
b. Potassium fluoride​
c. Water​
d. Hydrogen chloride

Answer 1

a. Sodium chloride is an ionic compound because the number of electrons in the valence shell of Na is 1. The number of electrons in the valence shell of Cl is 7. So, Sodium donates its valance electron to chlorine and forms an ionic bond.

b. Potassium fluoride is an ionic compound because the number of electrons in the valence shell of K is 1. The number of electrons in the valence shell of F is 7. So, potassium donates its valance electron to fluorine and forms an ionic bond.

c. Water is a covalent compound because the number of electrons in the valence shell of H is 1. The number of electrons in the valence shell of O is 6. So, both hydrogen will share its valence electrons with oxygen and form a covalent bond.

d. Hydrogen chloride is a covalent compound because the number of electrons in the valence shell of H is 1. The number of electrons in the valence shell of Cl is 7. So, hydrogen will share its valance electrons with chlorine and form a covalent bond.
