atoms are shared so as to satisfactorily fill the outer electron shells of both atoms.
Covalent bonds, which hold the atoms within an individual molecule together, are
... A carbon atom has four electrons in its outermost orbitals; it usually forms four
bonds ... Nitrogen and phosphorus each have five electrons in their outer shells,
... Bond angles give these water and methane molecules their distinctive shapes.
Each of the bonded atoms retains its atomic orbitals, but the electron pair of the
overlapping ... These bonds have a specific geometry and a bond angle of 109.5°
. 2. .... One electron is shared with carbon and the other is shared with a
