Group 0 Noble Gases
Key knowledge — The Periodic Table
Key facts & rules
- Periods: rows — number of electron shells increases across a period. Group: columns — same number of outer electrons.
- Group 1 (alkali metals): react with water → metal hydroxide + hydrogen. Reactivity increases DOWN the group.
- Group 7 (halogens): diatomic molecules (F₂, Cl₂, Br₂, I₂). Reactivity DECREASES down group. More reactive halogen displaces less reactive one.
- Group 0 (noble gases): full outer shell → very unreactive, exist as single atoms.
- Transition metals: in the middle block. Variable oxidation states, form coloured compounds, good catalysts.
- Metallic character increases down a group and decreases across a period (left to right).
- Across period 3: Na, Mg, Al are metals; Si is metalloid; P, S, Cl, Ar are non-metals.
