There are rows labeled in the periodic table. Look at the first digit of the row number Ex: 1 or 18, the numbers determine the valence electrons (1-8)
The first energy level has a maximum of two valence electrons. The second and third energy levels have a maximum of 8 valence electrons.
Aluminum (Al) will have 3 electrons in its valence shell, which is the outermost electron shell.
An easy way to determine how many valence electrons an atom has is by looking at the periodic table. The first two columns on the left of the periodic table and the last six on the right are the elements which have valence electrons. Each column represents 1 valence electron. So column one has one valence, column two has two valence. Only counting the first 2 and the last 6 six columns, Carbon is is column four, which means it has four valence electrons.
Look what column it is in within the Periodic Table. The first column has 1 valance electron. The second column has 2 valence electrons. The entire section of shorter columns (all metals) also have two valence electrons. The tall column after that (with Boron ) has three valence electrons. The tall column after that (with carbon) has four valence electrons. This pattern continues until you reach the final column, the noble gasses (eg. Neon, argon, xenon); these all have 8 valence electrons.
His name is Charles Barkley.
Frances Barkley was the 17-year-old wife of Captain Charles William Barkley. She is considered to be the first European woman to have ever visited Canada's west coast.

The first great awakening of the US was in the1730s-1740s.

Where did gene Barkley go after the first season
Barkley, also known as "the round mound of rebound" went to Auburn University for three years. He was drafted in the first round of the NBA draft in 1984.
The first energy level has a maximum of two valence electrons. The second and third energy levels have a maximum of 8 valence electrons.

It is the instrumental of 'Run' by Gnarls Barkley.
