Study Notes
Valency
- Valency refers to the combining power of an element, which is the number of electrons an atom of that element can lose, gain, or share to form bonds with other atoms.
Elements with Specific Valency
- An element with a valency of 3 that is commonly found in compounds with oxygen is iron (Fe).
Valency in Compounds
- In the compound NaCl (sodium chloride or common table salt), the valency of sodium (Na) is 1 and the valency of chlorine (Cl) is 1.
Atomic Structure
- The outermost shell of an atom is called the valence shell.
Chemical Bond Formation
- Electrons are the subatomic particles responsible for the formation of chemical bonds.
Chemical Properties
- The chemical properties of an element are determined by the number of electrons in its outermost energy level (valence shell).
