7
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.
No, the number of valence electrons is not always equal to the number of protons. The number of valence electrons is determined by the group number of an element on the periodic table, while the number of protons is the atomic number of the element.
The element that has a mass number of and two valence electrons is an isotope of calcium.
The number of valence electrons. :) have a good day breh
the number of protons is always equal to the number of electrons only then the atom will be stable hence there are 17 electrons in chlorine 36
The number of valence electrons is seven.
There are 7 valence electrons!🤓
Chlorine has 7 electrons in the outermost shell. It is in the 17th group. It has 7 valence electrons.
There are 7 valence electrons in chlorine.
There are 7 valence electrons in chlorine.

Chlorine has 7 electrons in the outermost shell. It is in the 17th group. It has 7 valence electrons.
A total of 7 valence electrons. If I remember correctly, the number of valence electrons of all group A elements are designated by their group number. Chlorine is in group VIIA, hence 7 valence electrons.
Boron has 3 valence electrons.Boron has 3 valence electrons.
2 valence electrons for calcium and 7 for chlorine.
The maximum number of valence electrons that an atom can have is 7, as seen in elements such as fluorine, chlorine, and bromine. These elements are in group 7A of the periodic table, also known as the halogens.
To determine the number of valence electrons for an element on the periodic table, you look at the group number of the element. The group number tells you how many valence electrons the element has. For example, elements in group 1 have 1 valence electron, elements in group 2 have 2 valence electrons, and so on.
