- Group 1 (Alkali Metals)
- Sodium (Na)
- Lithium (Li)
- Potassium (K)
- Rubidum (Rb)
- Caesium (Cs)
- Francium (Fr)
- Physical Properties & Facts
- Highly Reactive
- Reactivity increases down Group 1
- They need to be stored in oil to avoid vigorous reactions with
- Oxygen
- Oxides
- Peroxides
- Superoxides
- Halogens
- Ionic Salts
- Oxygen
- Low density
- Silvery Colour
- Soft texture
- Low melting and boiling point
- They decrease down Group 1
- Atomic size increase down the group
- Larger atomic radius
- Weak Metallic Bonds
- Delocalised electrons further away from the nucleus
- Only have one electron to contribute to the 'sea' of delocalised electrons
- Weak Metallic Bonds
- They decrease down Group 1
- Highly Reactive
- The outermost valence electron is more likely to be removed
- Electron donors (during reactions)
- Cations
- Low ionisation energy
- Highly Reactive
- Reactivity increases down Group 1
- They need to be stored in oil to avoid vigorous reactions with
- Oxygen
- Oxides
- Peroxides
- Superoxides
- Halogens
- Ionic Salts
- Oxygen
- Highly Reactive
- Electron donors (during reactions)
- Great distance between neighboring atoms in a metallic lattice
- Lower termal energy needed to separate the atoms
- Atomic size increase down the group
