Group 2 - Alkaline Metals

Properties

Atomic Radius: Atomic radius increases as you go down the group as a electron shell is increased

Ionisation Energy: As you go down a group there is an extra shell each time therefore there is increased shielding. Due to extra shell, the outer electrons are further away rom the nuleas therefore less energy is needed to remove the electron as there is less attraction between outer electon and protons from the nucleas

Reactivity: As you go down the group the reactivity increases as due to the extra shell and shielding, electrons are further away from the nucleas therefore it is easier to lose a electron

Melting Point: As you go down the group the melting point decreases, as the atomic radium increases the delocalised electrons become further away from the nucleas therefore less energy is needed to break the…
