it is negative because it appears in non metals them selves
In a covalent bond, each atom retains its outer shell of electrons. The atoms share pairs of electrons to achieve a full outer shell, which makes the bond stable.
Carbon needs 4 covalent bonds to fill its outer shell.
A compound that shares electrons is a covalent compound. In covalent bonding, atoms share electrons to achieve a full outer shell and form a stable molecule. Ionic compounds involve the transfer of electrons from one atom to another, resulting in the formation of positive and negative ions held together by electrostatic forces.
Covalent bonds form when atoms share electrons to achieve a full outer shell, which makes them more stable. A full outer shell corresponds to the octet rule, which states that atoms are more stable when they have eight electrons in their outermost shell. By sharing electrons in covalent bonds, atoms can achieve this stable electron configuration.
Silicon needs four covalent bonds to fill its outer shell and achieve a stable electron configuration, similar to carbon in the context of organic chemistry.
The outer shell of an atom is populated by electrons, which have a negative charge. Protons, which have a positive charge hang out in the nucleus of the atom.
In a covalent bond, each atom retains its outer shell of electrons. The atoms share pairs of electrons to achieve a full outer shell, which makes the bond stable.
a chemical bond in which valence electrons are shared between atoms giving each of them a full valence shell is a covalent bond.
Ionic and covalent bonds both result in a full outer electron shell.
Carbon needs 4 covalent bonds to fill its outer shell.
A covalent structure is when two atoms share an electron to gain a fuller outer electron shell
A compound that shares electrons is a covalent compound. In covalent bonding, atoms share electrons to achieve a full outer shell and form a stable molecule.

By sharing electrons in covalent bonds, atoms can achieve this stable electron configuration.
When an atom forms an ion, the outer shell of the ion will have gained or lost electrons to achieve a full valence shell. For cations (positive ions), the outer shell will have fewer electrons than the neutral atom. For anions (negative ions), the outer shell will have more electrons than the neutral atom.
Helium, He, is neither covalent or ionic. It is a nobel gas, has a full outer shell 1s2, and has no known compounds
Silicon needs four covalent bonds to fill its outer shell and achieve a stable electron configuration, similar to carbon in the context of organic chemistry.
This has a positive ion as it only has 1 electron on its outer shell, so rather than gaining 7 for a full shell of 8, it loses 1 to have a full outer shell.The radius of the Li+ ion can be estimated by subtracting the radius of the I- ion .In each case, the negative ion is much larger than the atom from which it was formed.
