Carbon can both gain and lose electrons. We "see" it every day in the form of compounds or in pure substance.
An atom that gains or loses electrons is called an ion. If it gains electrons, it results in a negative ion called an anion. If it loses electrons, it results in a positive ion called a cation.
It's safe to say if an object gains or loses electrons its electric charge has changed. If it was overall electrically neutral before it lost electrons, it would then have a positive charge; if it acquired electrons from initially being neutral, it would have a negative charge. At the atomic level this is called ionization.

If an atom gains or loses electrons, it becomes an ion. If it gains electrons, it becomes a negatively charged ion called an anion. If it loses electrons, it becomes a positively charged ion called a cation.
When an atom gains electrons, negatively charged anions are formed. When an atom loses electrons, positively charged cations are formed.
An atom that loses electrons becomes a positively charged ion called a cation. An atom that gains electrons becomes a negatively charged ion called an anion.
When an atom loses electrons, it becomes a positively charged ion called a cation. When an atom gains electrons, it becomes a negatively charged ion called an anion.
The particle in question gains or loses electrons.

These are ionic bonds.
