2. Counting Valence Electrons: - As we move from left to right in the second period: - Lithium (Li) has 1 valence electron. - Beryllium (Be) has 2 valence electrons. - Boron (B) has 3 valence electrons. - Carbon (C) has 4 valence electrons. - Nitrogen (N) has 5 valence electron...
How many 2p atomic orbitals from boron must be mixed with a 2s atomic orbital to yield the bonding hybrid atomic orbitals in BF3? Explain how you got your answer. How many electrons can a 3p orbital hold? How many electrons can a 2s orbital hold? How many electrons can a 1s ...
The other part of a typical solar cell is doped with the element boron, which has only three electrons in its outer shell instead of four, to become P-type silicon. Instead of having free electrons, P-type ("p" for positive) has free openings and carries the opposite (positive) charge...

The octet rule says that many elements share an octet (8) of electrons in their valence (outermost) electron shell when they form compounds. A formal definition of the octet rule, from Northwestern University, states that "Atoms will lose, gain or share electrons to achieve the electron config...
