Valence Electrons in Metals
Metallic elements generally have a smaller number of valence electrons compared to nonmetals. Valence electrons are the electrons in the outermost shell of an atom that are involved in chemical bonding. In metals, these electrons are loosely held by the nucleus, allowing them to move freely and conduct electricity.
Option A: 1, 2 or 3
- Metals typically have 1, 2, or 3 electrons in their valence shell.
- For example, Group 1 elements like sodium have one valence electron, Group 2 elements like magnesium have two valence electrons, and Group 13 elements like aluminum have three valence electrons.
- These few valence electrons make metals more likely to lose electrons and form positive ions in chemical reactions.
In conclusion, metals generally have a small number of valence electrons, typically 1, 2, or 3, which contribute to their physical and chemical properties such as conductivity and reactivity.
