3.5.2 Test (CST): Computer-Scored Unit Test Question 17 of 25 What is required for two atoms to share electrons equally in a chemical bond? A. The two atoms must have the same number of valence electrons. B. The two atoms must have equal and opposite charges. C. The two atoms must both be nonmetals. D. The two atoms must be of the same element. SUBMIT

When two atoms share electrons equally in a chemical bond, they typically form a nonpolar covalent bond. This happens most often when the two atoms are the same element, as their electronegativities are identical, allowing for an equal pull on the shared electrons. Think of it as a perfectly matched tug-of-war with no winner – both sides exert the same force! In the real world, this is seen in molecules like O₂ (oxygen) and N₂ (nitrogen), where the atoms are identical, leading to a balance in electron sharing. These diatomic molecules are crucial for life as we know it, supplying the oxygen we breathe and playing a vital role in the atmosphere, making them a great example of equal electron sharing in action!
