Just as the valence electrons of atoms occupy atomic orbitals (AO), the shared electron pairs of covalently bonded atoms may be thought of as occupying molecular orbitals (MO).
Take the atomic number then subtract the amount of valence electrons. Example: Number of non valence (inner) electrons in Sulfur: 16 (atomic number) - 6 (valence electrons) = 10 (valence or inner electrons)
Krypton has 8 valence electrons.

Type your answer here... The number of valence electrons in calcium is 20, because it's almost the same thing as it's atomic number.
The atomic number for nitrogen is 7. Neutral nitrogen must have both 7 electrons and 7 protons then. The first 7 orbitals are filled as 1s2 2s2 2p3, which shows us that nitrogen has 5 valence electrons.
None, light is composed of photons. Light may be emitted or absorbed when electrons undergo transitions between atomic or molecular orbitals, but the light itself does not contain electrons.
Each orbital must contain a single electron before any orbital contains two electrons.
The "orbitals" round an atomic nucleus are electrons, in anti matter they are protons
