Question

How does the chemical reactivity of elements vary in a

Period

Answer 1

Along a period, the chemical reactivity varies as:

• The chemical reactivity of an element refers to an ease in forming a bond with other elements by forming an ionic or covalent bond.
• The elements react to complete their octets.
• Along a period, the size of an element decreases and the increase in effective nuclear charge which makes it difficult for an element to react.
• So, along a period the chemical reactivity decreases.
