Question

How periodicity of properties depend upon the number of protons in an atom?

Answer 1

The Periodicity of properties depends upon the number of protons in an atom as a result of physical and chemical properties.

Explanation:

• Atomic weight always depends on the number of protons and neutrons in the nucleus.
• Physical and chemical properties of the elements upon the atomic numbers not on the atomic weight.
• Periodic properties follow a trend.
• These properties are listed in order of increasing atomic number.
• These properties observe cyclical changes.
• Periodic properties of elements having the same properties recur at intervals.

Answer 2

Answer:chemical properties of elements depend upon electronic configuration which is based upon atomic number or number of protons.So arrangement of elements to increasing atomic number shows the periodicity in the electronic configuration of the elements that leads to periodicity in their properties.
