GCSE Chemistry - Metals & Non-metals: Electron Arrangement & Properties

Подробнее о видео

⭐️ ⭐️

*** WHAT'S COVERED ***
1. Introduction to Metals and Non-metals
* Location on the periodic table.
* Tendency of metals to form positive ions
* Tendency of non-metals to form negative ions or no ions
* The role of electron arrangement in achieving a full outer shell and ion formation.
2. Reactivity Trends in Metals
* How metals become more reactive further down their group.
* Explanation based on the number of electron shells and the ease of losing outer electrons.
3. Physical Properties of Metals
* Overview of metallic bonding and its strength.
* Properties including malleability, good conductivity of heat and electricity, high melting and boiling points, being shiny, and sonorous.
4. Physical Properties of Non-metals
* General characteristics such as being dull in colour, brittle, having low melting and boiling points (many are gases at room temperature), poor conductivity of electricity, and lower densities.
5. Transition Metals
* Location in the centre of the periodic table.
* Possession of typical metal properties.
* Distinctive additional properties:
* Ability to form more than one type of ion.
* Formation of coloured ions.
* Use as effective catalysts, including a definition of catalysts and examples (Iron in the Haber process, Nickel in the hydrogenation of alkenes).
