Carbon dioxide contains chemical bonds between oxygen and carbon. What particles are between the carbon and oxygen atoms? What keeps those particles between the atoms?

Explanation: i stuck at this Sometimes atoms share more than one pair of electrons, for example a double covalent bond can occur, as in the carbon dioxide molecule where carbon shares 2 pairs of electrons with each oxygen atom: O=C=O. (where = represents a double bond). Another kind of covalent bonding is called co-ordinate or dative covalent.
