The valence is determined experimentally.
You can determine how many valence electrons an atom has by what family the element of the atom is in. For instance, if the element is in family 8A, the number of valence electrons will be 8. Or, if the element is in family 2A, the number of valence electrons for the atom will be 2. So, whatever number family the atom is in, the number of valence electrons equals that.
the number of valence electrons in the atom's outer shell how much the valence electrons are shielded from the nucleus
Valence electrons are the electrons in the outermost shell. They are the electrons available for bonding and generally determine the number of bonds an atom can make
Electrons in the outermost energy level are called valence electrons. The number of valence electrons on an atom largely determine its behavior and characteristics.
They are on the outside of the atom. (Apex 2021)

Because charge only reveals the number of valence electrons of an atom while the identity of an atom also relies on the number of non-valence electrons.
In the neutral atom of a chemical element number of electrons= number of protons=atomic number.
It's determine by the vacancy (unfilled orbital) in the outermost shell of an atom.
The number of unpaired electrons in the outermost shell determines the number os covalent bonds an atom can form.
they determine the difference between the elements like a hydrogen atom has 1 electron and carbon has 6
To find the number of valence electrons in an atom of a representative element, all you have to do is look at its group number. Ex: Group 1 (Hydrogen, Lithium, Sodium, Potassium, ect.) All have 1 valence electron.
The electron. The electron is has a negative charge. The more electrons that are in a valence shell of the atom the more negative the atom will be.
A calcium atom has two valence electrons.
The most valence electrons an atom can contain is eight.
6 valence electrons
