2. Groups/Families on the Periodic Table
Elements on the periodic table can be grouped into families bases on their chemical properties.
Each family has a specific name to differentiate it from the other families in the periodic table.
Elements in each family
react differently with
other elements.

3. ALKALI METALS Group 1: Alkali Metals
Group Contains: Metals
Electrons in the outer level: 1 (valence electron)
Reactivity: VERY reactive
**Hydrogen is NOT part of this group
Image:

4. Alkali Metals - cont. Sodium (Na) Atomic # 11 11 P 11 E 12 N
1 Valence Electron

5. ALKALINE EARTH METALS Group 2: Alkaline-Earth Metals
Group Contains: Metals
Electrons in the outer level: 2
Reactivity: VERY reactive,
but less reactive
than alkali metals

6. Alkaline-Earth Metals - cont.
Magnesium (Mg)
Atomic # 12
12 P
12 E
12 N
12 P
12 N
2 Valence Electrons

7. Alkaline-Earth Metals - cont.

8. TRANSITION METALS Groups 3-12: Transition Metals
Group Contains: Metals
Electrons in the outer level: 1 or 2
These elements make the
transition from metals to
metalloids

9. BORON FAMILY Group 13: Boron Group Group Contains: 1 metalloid &
4 metals
Electrons in the outer level: 3

10. CARBON FAMILY Group 14: Carbon Group Group Contains: 1 non metal,
2 metalloids & 2 metals
Electrons in the outer level: 4

11. NITROGEN FAMILY Group 15: Nitrogen Group Group Contains: 2 non metals,
2 metalloids & 1 metal
Electrons in the outer level: 5

12. OXYGEN FAMILY Group 16: Oxygen Group Group Contains: 3 non metals,
1 metalloid & 1 metal
Electrons in the outer level: 6

13. Halogens Group 17: Halogens Group Contains: Nonmetals
Electrons in the outer level: 7
These elements will be VERY REACTIVE nonmetals

14. Noble Gases Group 18: Noble Gases Hjhhhhhhjmhh
Group Contains: NonMetals
Electrons in the outer level: 8
(2 for Helium)
Reactivity: UNREACTIVE
**These elements do not
need to bond with other elements

15. TRANSITION METALS – Cont.
Lanthanides & Actinides
From periods 6 & 7
Placed at the bottom of the
bottom of the periodic table
to keep the table from being
too wide
They get their name from the
two elements that precede their
rows

16. Hydrogen Group: Hydrogen Stands Alone
Electrons in the outer level: 1 (valence electron)
Reactivity: VERY reactive
Colorless, odorless gas at room temperature
Reacts violently with oxygen
Most abundant element in the universe
**Hydrogen’s properties do not match any one group, so it is in a group by itself

17. Hydrogen Group – cont. Similar to Group 1 (Alkali Metals)
(Halogens)
Only have 1 valence electron
Colorless, odorless gas
Very reactive
Nonmetal
