Question

The electronegative values of given elements in the table represents
a) Decreases from top to bottom in a group
b) Decreases from left to right in a period
c) Increases from top to bottom in a group d) Decreases from right to left in a period​

Answer 1

Answer:

a is correct Electronegativity decrease from top to bottom

Explanation:

as we move down the group the atomic size increases so the distance from the centre of nucleus to the outermost valence shell electron goes far away and hence the ability to attract the electron degrees

Answer 2

Answer:

option a) Decreases from top to bottom in a group

Explanation:

This is because atomic number increases down a group, and thus there is an increased distance between the valence electrons and nucleus, or a greater atomic radius.
