one valence electron
they all have one valence electron.
To start off, the electrons on the outermost energy level of an atom are called valence electrons. You can tell how many valence electrons an energy level has by finding out its group number. If an element is in group one, than it has one valence electron.
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.
This is a chemical element. You can find the how many electron in a single atom by using a periodic table.
The group of the element indicates the amount of valence electrons. For example, the alkali metals have one valence electron and is in group one whilst the halogens have seven valence electrons and are in group seven.
To determine the number of valence electrons in an element, you look at the group number on the periodic table. The group number tells you how many valence electrons an element has. For example, elements in group 1 have 1 valence electron, elements in group 2 have 2 valence electrons, and so on.
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.

Barium is a group 2 element. All group 2 elements have 2 valence electrons. Thus, barium has 2 valence electrons.
Boron has 3 valence electrons.Boron has 3 valence electrons.

This element is sulfur; the electron configuration of sulfur is [Ne]3s23p4. Sulfur has three electron shells cotaining 2, 8 and 6 electrons. The last six are valence electrons.
This is a chemical element. You can find the how many electron in a single atom by using a Periodic Table.

A cesium atom has 1 valence electron. It is an alkali metal, and all alkali metals have 1 valence electron. The electron configuration for cesium is (Rn)7s1. The single electron in the 7s sublevel is its valence electron.
