By finding the atomic number minus the group number
To determine the number of valence electrons, you look at the group number of an element on the periodic table.
To determine the number of electrons for an element on the periodic table, you can look at the element's atomic number. The atomic number represents the number of protons in the nucleus of an atom, which is equal to the number of electrons in a neutral atom.
To determine the number of valence electrons for 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.
To determine the number of valence electrons for an element using 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.

To determine the number of electrons in an element, you can look at the atomic number of the element on the periodic table. The atomic number represents the number of protons in the nucleus of an atom, which is equal to the number of electrons in a neutral atom.
Each group/family on the periodic table can determine valence electrons by the last number of the group/family number, like helium. It's a noble gas that has 8 valence electrons because it's on the 18 family/group
Periodic table lists the elements in the increasing order of atomic number. Atomic number = Number of protons = Number of electrons
