The number of valence electrons is seven.
Chlorine has 7 valence electrons.
In every chlorine atom, there are seven valence electrons.
Cl has 7 valence electrons.
The hydrogen ion H+ is without electrons.
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.
The number of valence electrons is seven.
Chlorine has 7 valence electrons.
The element chlorine has seven electrons in its valence shell.
A neutral atom of fluorine contains 7 valence electrons.
I believe there is 8 electrons in the outer valence
Fluorine atom has seven valence electrons.
In every chlorine atom, there are seven valence electrons.
Fluorine is a halogen. All halogens have 7 valence electrons. There are thus 7 valence electrons for Fluorine, 2 in the 2s orbital, and 5 in the 2p orbitals.
there are 17 electrons in chlorine. and 7 of them are valence electrons.
A chlorine atom has 7 valence electrons.
Fluorine and Chlorine are in the 7th group. They have 7 electrons in outer shell.
