Question

Positions of four elements x y z and p in the modern periodic table of zone given given below which of the following is the correct order of increasing electronic negativity of the elements​

Answer 1

Answer:

p,X, y,z

Explanation:

because down the group the electronegativity increases

Answer 2

The general trend for increase in electronegativity is from left to right in a period, electronegativity increases.

1) This happens because the number of shells remain same along a period in the elements but the number of protons increases which increases the Zeff.

2) The increase in Zeff results in the increase of electronegativity as the electrons are pulled towards the nucleus.

3) Down the group electronegativity decreases as number of shells increase but number of valence electrons remain same.
