Answer:

Explanation:

If an electron is in an excited state it can return to a lower energy level. When it does this, it loses energy. The amount of energy it loses will be equal to the difference in the energy levels it moves between. This energy is released as a photon.

for each pair of compounds below , identify the one that would be expected to have more ionic character.explain you choice. (a)N

Tju [1.3M]

Answer:

a)NaBr

b)FCl

Explanation:

To identify which compound is more ionic we will calculate the electronegativity difference.

A) NaBr

Electronegativity of Na = 0.93

Electronegativity of Br = 2.96

Electronegativity difference = 2.96- 0.93 = 2.03

HBr

Electronegativity of H = 2.2

Electronegativity of Br = 2.96

Electronegativity difference = 2.96 - 2.2 = 0.76

NaBr have more ionic character because of large electronegativity difference.

B) BrCl

Electronegativity of Cl = 3.16

Electronegativity of Br = 2.96

Electronegativity difference = 3.16 - 2.96 = 0.2

FCl

Electronegativity of F = 3.98

Electronegativity of Br = 2.96

Electronegativity difference = 3.98 - 2.96 = 1.02

FCl have more ionic character because of large electronegativity difference.
