Question

Give Reasons:1.Halogens have high electron affinity. 2.Anion is larger than parent atom. 3.The size of the atoms of inert gases is bigger than Halogens of the same period. 4.Atomic number is the fundamental property of an element.

Answer 1

Answer:

1.halogens have high electron affinity, because unstable electronic configuration to gain stable form.

2.because of they gain electrons.

3.because of, along the period inert gases are stable element.either gain not lose.

4.atomic number is about the protons and electrons.

Answer 2

Answer:

1) as their effective nuclear charge is more

2) as repulsion increases due to extra electron

3) as config. is complete octet and vanderwaals radius

4) on it properties of an element depends
