What types of atoms typically form covalent bonds?
a) Metals with nonmetals, because their difference in electronegativity is above 1.7.
b) Metals with nonmetals, because their difference in electronegativity is below 1.7.
c) Nonmetals with nonmetals, because their difference in electronegativity is above 1.7.
d) Nonmetals with nonmetals, because their difference in electronegativity is below 1.7.

Answer 1

What types of atoms typically form covalent bonds?

The correct answer:

d) Nonmetals with nonmetals, because their difference in electronegativity is below 1.7.

En example to explain:
An example of a covalent bonding: HCl -> 2 nonmentals
-> a difference in electronegativity less than 1.7:

EN(Cl) = 3.0 and EN (H) = 2.1 (you can search these values in a periodic table)
/\EN = 3.0 - 2.1 = 0.9

0.9 < 1.7

I hope this helped you out!

Answer 2

The correct answer is d.

Step-by-step explanation:

A covalent bond between two atoms occurs when they join together to reach the stable octet, sharing electrons located at the last level. The electronegativity difference between the atoms must be less than 1.7 so that an ionic-type bond does not occur.

The two atoms share one or more pairs of electrons in a new type of orbital called molecular. Covalent bonds occur between atoms of the same non-metal element, between different non-metal atoms, and between a non-metal atom and the hydrogen atom.

Have a nice day!
