ozone and ammonia
Only Ozone is right answer as it contains three atoms of oxygen.
Ammonia has one atom of Nitrogen and three atoms of Hydrogen! so it is a tetra atomic molecule.
Two atoms - Diatomic Molecule Three atoms - Triatomic Molecule
A diatomic element exists as a molecule containing two of its atoms, such as chlorine (Cl2) and bromine (Br2). Elements that are not diatomic include monatomic elements (noble gases such as Ar, Ne) and triatomic elements (ozone, O3).
Each of two or more different physical forms in which an element can exist.
Elements
A triatomic molecule is a molecule consisting of 3 atoms (the same or different). Examples of triatomic molecules include (but not limited to): - Water (H2O) - Ozone (O3) - Carbon dioxide (CO2)
A diatomic element exists as a molecule containing two of its atoms, such as chlorine (Cl2) and bromine (Br2). Elements that are not diatomic include monatomic elements (noble gases such as Ar, Ne) and triatomic elements (ozone, O3).
These elements are francium and lithium.
