Since fluorine and chlorine are in family 7A, they each have 7 valence electrons. The number of the family corresponds to the number of valence electrons.
Nitrogen has 7 electrons, oxygen has 8 electrons, and chlorine has 9 electrons. That is the total electron count, for inner and outer shells. If you are only concerned with the valance electrons, then it is 5 for nitrogen, 6 for oxygen, and 7 for chlorine.
flurine has atomic no. 9 so its electronic configaration is 2,7. Its valance shell has 7 electrons
By looking at the group number you can tell how many valance electrons there are ex: Group 1= 1 valance electrons Group 2-12= 2 valance electrons Group 13= 3 valance electrons Group 14= 4 valance electrons Group 15= 5 valance electrons Group 16= 6 valance electrons Group 17= 7 valance electrons Group 18= 8 valance electrons
Five. Fluorine and chlorine are in the 2p and 3p shells, respectively. Because each p orbital contains a maximum of six electrons, and fluroine and chlorine both have one less, they each have five.

Fluorine and Chlorine are in the 7th group. They have 7 electrons in outer shell.

chlorine has 6 electrons in the outer shell. although these have a special name, they are called valance electrons.

A fluorine atom has 7 valance electrons. This can be identified by looking which group fluorine is located, which is group 7. However when the atoms get bigger this rule does not apply so easily.
The number of valence electrons is seven.
in a normal F- ion there are 10 electrons total (but 8 in the outer energy level)
Nitrogen has 7 electrons, oxygen has 8 electrons, and chlorine has 9 electrons. That is the total electron count, for inner and outer shells. If you are only concerned with the valance electrons, then it is 5 for nitrogen, 6 for oxygen, and 7 for chlorine.
