A covalent bond is a bond in which electrons are shared between atoms of elements
A covalent bond is a
bond in which electrons are shared between atoms of elements. A
covalent bond can be polar or nonpolar. In a nonpolar covalent
bond, the bond is between two identical atoms and the electrons are
evenly shared between the atoms.In contrast, in a
polar covalent bond, the bond is between two nonidentical atoms and
the electrons are unevenly shared between the atoms. The uneven
sharing of electrons takes place because of the difference in the
electronegativity...

Answer 1-4 (#3 and #4 are tables)
shell provides stability to the atom. Different chemical bonds are based on the way in which the atoms fill their valence shells. The major types of chemical bonds include: ionic bonds covalent bonds (both types, i.c. polar covalent and non-polar covalent bonds), and hydrogen bonds. Atoms can use two strategies to fill their valence shell: they can share electrons between their valence shells, or they can give or take electrons from other nearby...
