The first 30 elements of the periodic table are classified in groups like so;


Group 1A

Hydrogen (H)
Lithium (Li)
Sodium (Na)
Potassium (K)

Group 2A
Beryllium (Be)
Magnesium (Mg)
Calcium (Ca)

Group 3A
Boron (B)
Aluminum (Al)

Group 4A
Carbon (C)
Silicon (Si)

Group 5A
Nitrogen (N)
Phosphorus (P)

Group 6A
Oxygen (O)
Sulfur (S)

Group 7A
Fluorine (F)
Chlorine (Cl)

Group 8A
Helium (He)
Neon (Ne)
Argon (Ar)


Elements Scandium (Sc), Teetanium (Ti), Vanadium (V), Chromium (Cr), Manganese (Mn), Iron (Fe), Cobalt (Co), Nickel (Ni), Copper (Cu), and Zinc (Zn), which are transition metals, are classified under Groups 3B, 4B, 5B, 6B, 7B, 8B, 9B, 10B, 11B and 12B respectively.

Funny, the computer would not let me spell the element after Scandium properly, because it contains what is considered a swear word. The real spelling is T-itanium

Please mark as best answer if you appreciate my efforts.
