Which of the following groups is characterized by both a high ionization energy and a low electron affinity?
A. Alkali metals (group 1)
B. Transition metals (groups 3-12)
C. Halogens (group 17)
D. Noble gases (group 18)

Respuesta :

Answer:

Noble gasses have high ionization energy and low electron affinity.

D is correct option.

Explanation:

Given that,

The following groups is characterized by both a high ionization energy and a low electron affinity

A. Alkali metals (group 1)

B. Transition metals (groups 3-12)

C. Halogens (group 17)

D. Noble gases (group 18)

We know that,

Ionization energy :

In periodic table, the ionization energy increase from bottom to top in a group and left to right in period .

Small atoms have high ionization energy and large atoms have low  ionization energy.

Electron affinity :

In periodic table, the electron affinity decreases from top to bottom in a group and right to left in period .

Large atoms have low electron affinity and small atoms have high electron affinity.  

According to given group,

Alkali metals are present in first column in periodic table.

Noble gases are present at last column in periodic table.

So, according to trend,

Hence, Noble gasses have high ionization energy and low electron affinity.

D is correct option.

The Nobel gases has both high ionization energy and a low electron affinity.

Option D is correct

  • The ionization energy is defined as amount of energy required to remove an electron from an isolated atom or molecule.
  • The electron affinity is defined as the amount of energy liberated when an electron is added to a neutral atom to form a negatively charged ion.
  • The Nobel gases has both high ionization energy and a low electron affinity because noble gases have a full octet, their ionization energies are actually quite high.
  • Noble gases have stable electron configuration, they have very low electron affinities
