Across 3. Most reactive of the first three group 1 elements 4. The number of outer electrons Group 1 elements have. 10. The number of shells indicates the ______________ of the Periodic Table an element is found in. 11. This increases as the Group is descended meaning the outer electrons are further from the nucleus 12. Group 1 elements are all __________________. 13. The _______________ of the outer electrons increases as the Group is descended by the full inner shells of electrons.

Down 1. As Group 1 is descended the lements become ___________ reactive. 2. This decreases as the Group is descended because the electrons wil be further from the nucleus 5. Metal _________________ are made when Group 1 elements react with water 6. Name given to Group 1 7. Li 8. This is where electrons are found. 9. Gas produced when Group 1 react with water
