Atom loose or gain electron to make its octet complete. It is done to achieve inert state.
To form a molecule, atoms can share, lose, and gain electrons
When atoms lose and gain electrons, an ionic bond will form. When atoms share electrons, a covalent bond will form.
They will loose electrons.
They need to gain them.
This depends on the electronegativity of atoms.
they share electrons
Atoms in the oxygen family can gain or share two electrons in order to achieve an octet of electrons.
carbon atoms cannot form ionic bonds because it can neither gain or loose electrons as it has 4 electrons in its valence shell.so it share its electrons which forms covalent bond.
Yes.
Some atoms lose electrons, some gain electrons, and some share electrons depending on what elements are involved and what compound is forming.
Atoms gain, share, or lose electrons to try and become more stable. Atoms will gain, share, or lose electrons until they have a stable 8 valence electrons in their outer shell which is called an octet, which is stated in the octet rule. See the attached links for information on the octet rule.
Because they don't have a full outer shell of electrons, 2,8,8,18
