Question

Put the pairs of atoms in order, with the pair that has the biggestelectronegativity difference between the two atoms at the top of your list.| Oxygen and strontiumt Aluminum and oxygent Chlorine and cesium11 Phosphorus and lithiumf Bromine and bromine

Answer 1

Step-by-step explanation:

We have to order some pair of atoms. We have to look for the electronativity difference between them. We can look for the electronagitivity difference of each pair and then compare them.

Oxygen and strontium:

Electronegativity of O = 3.44

Electronegativity of Sr = 0.95

ED O-Sr = 3.44 - 0.95

ED O-Sr = 2.49

Oxygen and aluminum:

Electronegativity of O = 3.44

Electronegativity of Al = 0.95

ED O-Al = 3.44 - 1.61

ED O-Al = 1.83

Chlorine and cesium:

Electronegativity of Cl = 3.16

Electronegativity of Cs = 0.79

ED Cl-Cs = 3.16 - 0.79

ED Cl-Cs = 2.37

Phosphorus and lithium:

Electronegativity of P = 2.19

Electronegativity of Li = 0.79

ED P-Li = 2.19 - 0.98

ED P-Li = 1.21

Bromine and bromine:

Electronegativity of Br = 2.96

ED Br-Br = 0

Answer:

ED O-Sr = 2.49

ED Cl-Cs = 2.37

ED O-Al = 1.83

ED P-Li = 1.21

ED Br-Br = 0
