Question

Which of these dose not reflect the periodicity of the elements [UPSEAT 2001; BIT 1990; MP PMT 2001]
A) Bonding behaviour B) Electronegativity C) Ionization energy D) Neutron/proton ratio

Answer 1

the answer to your question is option A

Answer 2

Answer:

Option D

Explanation:

The neutron/proton ratio does not reflect the periodicity of elements. Rest are all periodic properties of elements. The neutron-proton ratio (N/Z ratio or nuclear ratio) of an atomic nucleus is the ratio of its number of neutrons to its number protons. It basically increases with the increase in atomic number unevenly.
