negative ion
Noble gases have a set of eight outermost electrons, which forms a stable electron configuration known as an octet. This full outer shell makes noble gases highly stable and unreactive under normal conditions.
No. Carbon has four valence electrons and can make four bonds.
An atom in which the outermost energy level is more than half full tends to fill its outermost energy level by adding one or more needed electrons. Such an atom forms a negative ion.
The latent valency of carbon in carbon monoxide is 2. Carbon in carbon monoxide forms a double bond with oxygen, utilizing 2 of its valence electrons to fulfill the octet rule.
Carbon does not gain or lose 4 electrons to complete its octet because it only has 4 valence electrons to begin with. To complete its octet, carbon forms covalent bonds by sharing electrons with other atoms to achieve stability due to its electronic configuration.
A black crystal with atoms having 4 electrons in its outermost energy level could be carbon, which forms a structure like graphite or diamond. In these structures, each carbon atom has 4 valence electrons, enabling it to form strong covalent bonds with other carbon atoms.

ionic bond
A phosphorus ion (P3-) has 8 electrons in its outermost energy level. This is because phosphorus has 5 electrons in its outermost shell, and when it gains 3 electrons to become an ion, it will have 8 electrons in total in its outermost energy level.
In an ionic bond, the valence electrons of one atom are transferred to another atom, creating positively charged ions (cations) and negatively charged ions (anions). The outermost electrons of the atoms are directly involved in the bond formation.
A carbon atom has four electrons in it's outermost energy level. Most atoms become stable when their outermost energy level contains eight electrons. A carbon atom therefore readily forms four covalent bonds with the atoms of other elements.
Magnesium forms a 2+ ion by giving away its two outermost electrons.
The sharing of electrons between atoms forms a covalent bond. If electrons are donated from one atom to another to form a bond this would be an ionic bond.
Carbon forms covalent bond when it shared electrons with other atoms.
Noble gases have a set of eight outermost electrons, which forms a stable electron configuration known as an octet. This full outer shell makes noble gases highly stable and unreactive under normal conditions.
Carbon does not readily form ionic compounds because it has a high ionization energy, meaning it requires a large amount of energy to remove electrons and form a stable cation. Instead, carbon tends to form covalent compounds by sharing electrons with other atoms to achieve a full outer shell configuration.
