Key Questions: |
- What is the common name given to the group 1 elements?
- Give 4 common properties of transition metal elements.
- Heat conductor, Electrical conductor, Lustrous (shiny), Dense, High melting and boiling point, High tensile strength, Strong, Hard
- Write a word equation for the reaction of sodium with chlorine.
- Sodium + Chlorine -> Sodium Chloride
- Describe the trend in reactivity in group 1 as you go down the group
- Reactivity of elements in group 1 increases as you go down the group (Lithium = least reactive, Francium = most reactive)
- For elements in Group 1, what do the properties depend on?
- Properties of the elements in Group 1 depend on the outer shell of electrons of the atoms
- Explain why elements become more reactive the further you go down group 1
- Elements in group 1 react by giving up their outermost electron. The further down the group you go the weaker the attraction between the nucleus of the atom and the outermost electron, as well as a greater amount of shielding. Therefore the electron is given up more easily.
- What are the transition elements?
- Metals with similar properties which are different from those of the elements in Group 1.
- Compare the properties of transition metal elements with those of the group 1 elements.
- Group 1 metals are soft, highly reactive to oxygen and water, form alkali solutions, are less dense than group 2 metals. Group 2 metals are harder, less reactive.
- Give examples of 3 transition metals
- Any three from the transition block eg. Cr, Mn, Fe, Co, Ni, Cu.
