6. What is the process one would go through when figuring
out how many valence electrons an element (not transition metals) has?
Reference the periodic table in your explanation.
In order to figure out the number of
valance electrons an element has one would simply use the periodic table. There
are trends and patterns that hold for figuring out how many valance electrons
each element has so the periodic table is a great tool in figuring this out.
The columns represent the group of elements and there are 18 groups. Group 1
has 1 valance electron. Group 2 has 2 valance electrons. Skipping over
transition metals, group 12 has 3 valance electrons while group 13 has 4
valance electrons and so on. Group 18, with the exception of Helium, have 8
valance electrons.
