The silicon based product of the earths crust in the oxygen, nitrogen, and halogen family. include many oxygen including selenium and tellurium frog through its skin.
There are 7 valence electrons in an NF3 molecule. Nitrogen has 5 valence electrons and each fluorine atom contributes 1 valence electron, totaling 3 electrons for the 3 fluorine atoms.
Oxygen has 6 valence electrons. A person can determine the number of valence electrons by looking at the periodic table. since oxygen is in the 6th column form the left, it has 6 valence electrons.
A halogen is located in group 17 of the periodic table, so the electron configuration for the valance electron would be ns2np5 (n=energy level). So all halogens have 7 valance electrons.
The difference is how many protons and electrons. Protons are positive, (both "p's" easier to remember) so if there are more electrons it's negative, less electrons it's positive. When atoms have electrons added or subtracted it changes the charge, then they are known as ions. The atomic number is how many protons there are, this never changes, if it does there is a different element.
For OF2, oxygen (O) has 6 electrons, and fluorine (F) has 9 electrons each. Therefore, the total number of electrons needed to form OF2 is 6 (from oxygen) + 2 x 9 (from two fluorine atoms) = 24 electrons.

Oxygen atoms have 6 valence electrons, while sulfur atoms have 6 valence electrons as well.
2 valance electrons
There are 27 valance electrons.
Iodine has 7 valance electrons
Basically the nonmetals. Many of them receive electrons, like oxygen, nitrogen, selenium, tellurium, and many others.
They have different numbers of valance electrons
