Valence electrons are in the outer shell of the atom. The first column (group 1)has a +1 valence, which means that it has an extra electron it can 'lose' when bonding with other atoms. The 2nd column (group 2) has +2. The same goes for groups 3. Group 4 can gain 4 and lose 4. Group 5 can 'gain' 3 electrons, group 6 can gain 2 electrons etc.

How do you work out the number of valence electrons in a substance?
Just get to know the periodic table of the elements; that is the key to understanding valence electrons.

They follow a pattern for valence electrons.
In an periodic table dots around an elements symbol indicate the number of valence electrons in an atom?
yes, the number of dots represent the number of valence electrons in the periodic table.
What type of elements have valence electrons?
Elements in every group of the periodic table has some number of valence electrons. The exception is, when it comes to group 18, the number of valence electrons might be considered as either 0 or 8.
