ATOMS AND MOLECULES
-
-
Isotopes are atoms of the same element while the same number of protons but different number of neutrons
same proton number, different nucleon number
Periodic table
Elements in the same group have similar chemical properties and will undergo the same type of chemical reactions
Group I Alkali metals
-
-
-
They all have one valence electron, and therefore can form ions of +1 charge
Group VII Halogens
-
-
-
They all have 7 valence electrons, and therefore can form ions fo -1 charge
Group 0 Noble gases
-
-
They all have fully filled electron shells. their atoms are said to have stable electronic configuration and therefore they are unable to react, bond, or form ions
