Question

Ionis atom energy of F- is equal in magnitude with the electron affinity of
a) F- b) F c) F+ d) F+2

Answer 1

Answer:

opition f f+ is the answer

Answer 2

Ionis atom energy of F- is equal in magnitude with the electron affinity of F

Explanation:

Ionisation energy:

• The energy needed to liberate an electron from a gaseous atom or ion is known as ionisation energy.
• The energy needed to remove one mole's worth of electrons from one mole of isolated gaseous atoms or ions is known as the first or initial ionisation energy, or Ei, of an atom or molecule.

$F^{(-)} - > F + e^{(-)} ;$

ΔH = +ve ⇔ $(IP)_{F^{-} }$

$F + e^{(-)} - > F^{(-)}$

ΔH = -ve  ⇔ $(EA)_{F}$

In madnitude

$(EA)_{F} = (IP)_{F^{-} }$

Final answer:

Ionis atom energy of F- is equal in magnitude with the electron affinity of F
