Question

An element having low value of ionization energy and low value of electron affinity is likely to belong to



(a) group 1

(b) group 15

(c) group 16

(d) group 18

​

Answer 1

Answer:

Group 18

Explanation:

An element that has low Ionisation energy(ie the possibility to form a cation) and low Electron Affinity(ie the possibility to form an anion) is most definitely a part of group 18 composed of stable noble gas elements...Thank you

Answer 2

An element having a low value of ionization energy and a low value of electron affinity is likely to belong to group 1 (OPTION A).

ALKALI METALS -

• Metals that belong to group 1 a are known as alkali metals.
• Metals react with water to form hydroxide which is basic in nature.
• The metals considered as alkali metals are - lithium, sodium, potassium, Rubidium, Cesium, and Francium.
• The valence electrons in the element are +1.
• They have the tendency to lose one electron so have the lowest ionization energy.
• They do not have the affinity to gain electron so show lowest electron affinity.
