The Periodic Table Part I – Categories of Elements

The Periodic Table H He Li Be B C N O F Ne Na Mg Al Si P S Cl Ar K Ca Sc Ti V Cr Mn Fe Co Ni Cu Zn Ga Ge As Se Br Kr Rb Sr Y Zr Nb Mo Tc Ru Rh Pd Ag Cd In Sn Sb Te I Xe Cs Ba La Hf Ta W Re Os Ir Pt Au Hg Pb Bi Po At Rn Fr Ra Ac Rf Db Sg Bh Hs Mt Ds Rg What do you notice about the way the element groups are arranged in the Periodic Table?
3
Periods Each row is called a “period”
The elements in each period have the same number of shells 1st Period = 1 Shell 2nd Period = 2 Shells 3rd Period = 3 Shells 4th Period = 4 Shells
4
Groups/Families Group 8 = 8 electrons Group 1 = 1 electron
Except for He, it has 2 electrons Group 2 = 2 electrons Each column is called a “group” 3, 4, 5, 6, 7 Each element in a group has the same number of electrons in their outer orbital, also known as “shells”. The electrons in the outer shell are called “valence electrons”

8
Transition Metals Transition Metals have slightly different rules for shells and valence electrons. This is something you will learn about in High School Chemistry.
9
Carbon - C 2nd Period = 2 shells 4th Group = 4 valence electrons
Determine the number of shells and the number of valence electrons for: 2nd Period = 2 shells 4th Group = 4 valence electrons Carbon - C
