Because energetically, it is favoured over the elements existing as separate atoms.
Covalent bonding can occur in solids, such as in diamond where each carbon atom forms covalent bonds with four other carbon atoms. However, in some solids, like metals and ionic compounds, the bonding is mainly metallic or ionic, respectively, due to the different types of interactions between atoms.
The first type of bond is a Covalent Bond. That bond forms when electrons are shared. and the second type of bond is Ionic bond, which is an electrical attraction between two oppositely charged atoms or groups of atoms called ions.
Covalent. [Although intermolecular bonding (hydrogen bonding and Van Der Waals) can occur between chains.]
Two atoms will form a covalent bond by the sharing of the valence electrons if the electronegativity difference between the two atoms is below 1.7
A bond is covalent if electrons are shared between atoms to form a stable molecule. Covalent bonds typically occur between nonmetals and involve the sharing of electrons to achieve a full outer electron shell. Characteristics of covalent bonds include the formation of molecules, low melting and boiling points, and poor electrical conductivity.

Intermolecular is the bonding between the molecules (what connects them all together) For example dispersion, dipole-dipole, hydrogen bonding (HFON)Intramolecular is the bonding between the atoms like ionic covalent or metallic.For example in a water molecule the intermolecular bonding would be the hydrogen bonding. The non-bonding pairs will connect with other water molecules non-bonding pairs to create a hydrogen bond. Whereas the intramolecular bonding would be covalent. Because that's what joins the individual hydrogen atoms to one oxygen atom.
Elements do not "occur" in bonds. Instead, elements form bonds between themselves. If the question means "Between what types of elements are covalent bonds likely to form?", the answer is "elements with very similar electronegativities". The smallest possible difference between electronegativities is that between two atoms of the same element, such as is present in the diatomic elements hydrogen, oxygen, nitrogen fluorine, chlorine, bromine, and iodine and in the polyatomic element carbon in its diamond crystal form.
bonding electrons are when the electron have the same number and the connect,like valence electrons. Non-bonding electrons are only possible when an atom is unstable, no more than 2 electrons or if the atom is an isotope. bonding electron pairs occur in a covalent bond between two atoms. they include one electron from each atom in the covalent bond. non-bonding pairs do not take part in bonding. they are the left over electrons in the outter shell of the atom.
covalent bonding
Nonmetals form covalent bonds.
Electrons are shared in covalent compounds to achieve a stable electron configuration for all atoms involved. By sharing electrons, each atom can complete its outer shell and attain a full valence shell, leading to increased stability and reduced overall energy.
Covalent bonds result from the sharing of electrons between atoms, creating a strong bond. They typically occur between nonmetals. Covalent bonds can be polar or nonpolar, depending on the electronegativity difference between the atoms involved.
