Answer:
Carbon is least likely to be part of an ionic bond.
Explanation:
- Ionic bond is formed by the process of transformation of electron between two atoms.
- In ionic bonds the charges of cations and anions are balanced.
- For the atom of carbon to form an ionic bond it must transfer 4 electron or gain 4 electron from another atom, this is not likely to occur in the chemical reaction.
- Hence carbon atom shares 4 electron so that it can have the configuration of noble gas.

Explanation:
organisms are typically grouped by how closely related they are, and thus clad is tics can be used to trace ancestry back to shared common ancestors.
