Question

why the trend of electron affinity and electronegativity same in period

Answer 1

Answer:

Eea generally increases across a period (row) in the periodic table, due to the filling of the valence shell of the atom. ... However, this trend applies only to Group-1 atoms. Electron affinity follows the trend of electronegativity: fluorine (F) has a higher electron affinity than oxygen (O), and so on.

Electron affinity: the energy change when a neutral atom attracts an electron to become a negative ion. Electronegativity: the ability of an atom in a molecule to draw bonding electrons to itself.

Answer 2

Answer:

Electronegativity is defined as a chemical property which decides the propensity of an atom to attract an electron. ... Electron affinity is defined as the amount of energy liberated when a molecule or neutral atom acquires
