To find the number of valence electrons of an element using the periodic table, you can look at the group number of the element. The group number indicates the number of valence electrons. For example, elements in Group 1 have 1 valence electron, elements in Group 2 have 2 valence electrons, and so on.
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.
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.

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.
There are only one electron. They are called alkaline metals.
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 Elements have a different Total Number of Electrons, but the same number of Valence Electrons.

This group has the electron configuration of sulfur. The element sulfur has 16 electrons, and its electron configuration is 1s2 2s2 2p6 3s2 3p4.
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.
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 identify the valence electrons of an element on the periodic table, look at the group number of the element. The group number indicates the number of valence electrons. For example, elements in Group 1 have 1 valence electron, elements in Group 2 have 2 valence electrons, and so on.
Boron has 3 valence electrons.Boron has 3 valence electrons.
