What are the combining elements in Carbon dioxide?

Molecular formula of Carbon dioxide:

1. The molecular formula of Carbon dioxide is $\mathbf{\left(}{\mathbf{CO}}_{\mathbf{2}}\mathbf{\right)}$.
2. This shows that Carbon dioxide has one carbon atom $\mathbf{\left(}\mathbf{C}\mathbf{\right)}$ and two oxygen atoms $\mathbf{\left(}\mathbf{O}\mathbf{\right)}$.

Combining elements in Carbon dioxide:

1. Carbon dioxide has one carbon atom $\mathbf{\left(}\mathbf{C}\mathbf{\right)}$ and two oxygen atoms $\mathbf{\left(}\mathbf{O}\mathbf{\right)}$
2. Thus, the combining elements in Carbon dioxide are carbon $\mathbf{\left(}\mathbf{C}\mathbf{\right)}$ and oxygen $\mathbf{\left(}\mathbf{O}\mathbf{\right)}$.
