Question

imagine that a classmate draws an electron dot diagram for a helium atom with two dots. he or she tells you that these dots mean helium atom has two unpaired electrons to have four pairs of valence electrons and become stable. What is wrong with your classmate's argument?

Answer 1

Answer:

The helium atom is already stable and doesn't need to bond with other atoms or share electrons. Helium's lowest energy level can only hold two electrons, which are paired.
