Electrons shared in a molecule are held more closely to the atom with the larger nucleus
Shared electrons in a water molecule are most likely found in the covalent bonds between the oxygen and hydrogen atoms. In water, the oxygen atom shares electrons with the hydrogen atoms to form two polar covalent bonds.
The HCl molecule is polar due to the difference in electronegativity between hydrogen and chlorine. Chlorine is more electronegative than hydrogen, causing the electrons in the bond to be unequally shared, resulting in a net dipole moment.
In a nonpolar covalent bond, the shared electrons are shared congruently throughout the molecule. This occurs when two atoms have similar electronegativities and therefore share the electrons equally.
In an iodine molecule (I2), a total of two electrons are shared between the two iodine atoms in order to form a covalent bond.
No, if electrons are shared equally between atoms in a molecule, the molecule is said to be nonpolar. A polar molecule occurs when there is an uneven distribution of electrons, leading to regions of partial positive and negative charges.
Shared electrons in a water molecule are most likely found in the covalent bonds between the oxygen and hydrogen atoms. In water, the oxygen atom shares electrons with the hydrogen atoms to form two polar covalent bonds.
The atom with the greater attraction for shared electrons in the molecule is the more electronegative atom.
The electrons in the water molecule are shared by oxygen and hydrogen atoms. However, the shared electrons are attracted more strongly by the oxygen nucleus than by the hydrogen nuclei. The water molecule therefore has partically positive and negative ends, or poles.

A Hydrogen bond.
In a nonpolar covalent bond, the shared electrons are shared congruently throughout the molecule. This occurs when two atoms have similar electronegativities and therefore share the electrons equally.
A covalent bond is held together by the attractions between the protons in the nucleus and shared electrons.
The Nitrogen Atom possesses seven protons in its nucleus; therefore the electrically neutral atom of Nitrogen has seven electrons in orbit about it.
The term for valence electrons in a molecule that are not shared is "nonbonding electrons" or "lone pair electrons". These electrons are not involved in chemical bonding and are typically found on atoms that have not formed any bonds with other atoms.
The electrons are shared in the diatomic hydrogen molecule.
In an iodine molecule (I2), a total of two electrons are shared between the two iodine atoms in order to form a covalent bond.
