Verified step by step guidance1
Identify the chemical formula of the molecule given, which is oxygen gas represented as \(O_2\).
Understand that the subscript '2' in \(O_2\) indicates there are two atoms of oxygen bonded together in one molecule.
Recognize that both atoms in the molecule are the same element, oxygen, so there is only one type of atom present.
Recall that the number of different types of atoms in a molecule corresponds to the number of distinct elements present in its formula.
Conclude that since \(O_2\) contains only oxygen atoms, the number of different types of atoms in one molecule of oxygen gas is 1.
