Question

Which of the following pairs of Lewis Dot diagrams shows two atoms that will form a covalent bond?

a) Na + Cl:
b) Al: + O
c) Li• + Br:
d) O + O

Answer 1

The pair of Lewis Dot diagrams representing two atoms that will form a covalent bond is d) O + O, as both are non-metal oxygen atoms sharing electrons.

Step-by-step explanation:

The question is asking which pair of Lewis Dot diagrams represent two atoms that will likely form a covalent bond. Covalent bonds typically involve the sharing of electrons between non-metal atoms. Analyzing the given options, d) O + O is the correct answer because both atoms are of the same element (oxygen) and will share electrons to complete their outer shells, forming a covalent bond.

For instance, when two chlorine atoms form a chlorine molecule (Cl₂), they share one pair of electrons. This can be represented using Lewis electron dot diagrams, similar to how two oxygen atoms would share electrons.
