Nonmetals with nonmetals, because their difference in electronegativity is below 1.7.
Explanation:
Covalent bond is the bond which is formed with the sharing of the electrons between the two atoms which are taking part in the bond. It is generally formed between the atoms with similar electronegativity values.
It is the bond which is generally occurs within non metals as they share electrons to complete their octet.
The difference in the electronegativity values of the atoms involving in a covalent bond must not exceed the value of 1.7 .
<u>Correct answer:- Nonmetals with nonmetals, because their difference in electronegativity is below 1.7.</u>
Over time the metal will cool and the water will heat up. Eventually the two objects will have the sametemperature. They are then said to be in thermal equilibrium with one another.
