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.
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.
NF3 has four charge clouds, consisting of three bonding pairs and one lone pair around the central nitrogen atom. This results in a trigonal pyramidal molecular geometry for NF3.
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.
Atoms of nonmetals can have up to 8 valence electrons. They tend to gain, share, or receive electrons to achieve a full outer electron shell. This allows them to reach a stable electron configuration, similar to a noble gas.
The electrons in the outermost shell of an atom are called valence electrons. These electrons are involved in forming chemical bonds with other atoms to create molecules. The number of valence electrons influences the reactivity and chemical properties of an element.
