Which of the following pairs of elements will not form an ionic bond with each other.

Sodium and lodine

Copper and Oxygen

Magnesium and Chlorine

Carbon and Sulfur

Explanation:

Sodium and Iodine are in columns 2 and 17. They will be ionic.

Copper and oxygen will be ionic. Oxygen is a powerful receiver of electrons.

Magnesium and Chlorine same answer as the first one.

Carbon and Sulfur. Not so much. They do not form an ionic bond. They are basically closer to being two non metals.

the number of protons in the nucleus of a given element. has slight luster and conducts electricity at high temperatures like metal.but like a nonmetal,boron is brittle and does not conduct electricity well at low temperatures. in graphite, carbon is a soft,brittle solid.it is reflective,ductile,or malleable.
