To make a sinle covalnt bond you only need TWO electrons. i think you mean can you have mlecules that do not achieve the octet and have only three electron pairs. The answer is yes- BF3 for example monomeric AlCl3 is another.
A normal covalent bond is a chemical bond formed by sharing of electron pairs between two atoms. It is a strong bond that holds atoms together in molecules. Each atom contributes one or more electrons to the bond, resulting in a stable electron configuration for both atoms.
Molecules or covalent compounds are formed by the sharing of valence electrons.
Hydrogen and germanium can form a covalent bond, where they share electrons to achieve a stable electron configuration. This bond is typically formed by sharing a pair of electrons between the two atoms.
False. Sharing valence electrons to make a bond creates a covalent bond, not an ionic bond.

Nitric oxide has a dative (coordinate) covalent bond. The N has donated both electrons and the O has also donated 2 electrons to make the N=O.

Phosphorus and sulfur can form a covalent bond when they chemically combine, sharing electrons to achieve a stable electron configuration. This type of bond involves the sharing of electrons between the atoms.
both are non-metals, so a covalent bond will be formed
A single covalent bonds involves the sharing of two electrons.
Not at all, in a covalent bond there is no losing or gaing of electrons as both of the atom reacting to make a covalent bond needs electrong therefore they share the electrons to stablized, but in ionic compound like NaCl, there is a losing of electron and gaining of electrons, therefore one element loses and one element gains. Ionic bond or "electrovalent bond" are strong bonds as compare to covalent bonds.
Two nonmetals would typically form a covalent bond, where they share electrons to achieve a stable electron configuration. This type of bond occurs when atoms are both trying to gain electrons to fill their outer electron shells.
Fluorine can make one covalent bond, as it has seven valence electrons and needs one more electron to complete its octet.
