Groups of Elements

Groups and Periods Groups (families): the vertical columns of the periodic table. Elements in the same group share chemical properties. What do the elements in the groups all have in common?

Groups and Periods Periods: One of seven horizontal rows in the periodic table. What do the elements in the periods all have in common?

Which atoms are these? Group 1, Period6 Group 16, Period 4

Chemical Families There are 4 main families of the periodic table. They are: Alkali Metals Alkaline Earth Metals Halogens Noble Gases

Alkali Metals Properties: Silvery grey, malleable, soft, conduct electricity and heat. Most reactive metals, react violently with water. Lithium, Sodium, Potassium, Rubidium, Cesium, Francium https://www.youtube.com/watch?v=m55kgyApYrY

Alkali metals

Alkaline Earth Metals Silvery-grey, malleable, slightly harder than alkali metals, conduct electricity and heat. Reactive, but not as reactive as the alkali metals Beryllium, Magnesium, Calcium, Strontium, Barium, Radium

Alkaline Earth Metals

Halogens Non-metals Solid, liquid and gases Brightly coloured Most reactive non-metals Fluorine, Chlorine, Bromine, Iodine,

Halogens

Noble Gases All Gases All non-metals Not Reactive Helium, Neon, Argon, Krypton, Xenon, Radon
