Electronegativity

[AlyssaBei_1F]

Does electronegativity have the same trend as electron affinity on the periodic table?

[Sara Flynn 2C]

yes, both decrease down a group and increase moving to the right in a period.

[Catly Do 2E]

Electronegativity is how efficient an atom can attract electrons and electron affinity is the energy released when an electron is added in the gaseous state to form an anion. Electronegativity increases and electron affinity gets more negative from left to right, and from bottom to top.

[Abhi4F]

Yes electronegativy and electron affinity both increase across due to a stronger nuclear attraction and decrease down as the number of shells increase making electrons further away from the nucleus.

Yes, I believe they are the same trends. However, I think that electron affinity is greater on the top right of the periodic table (like near the Nobel gases).
