Question

You have three elements, A, B, and C, with the following electronegativity values:

A = 3.3
B = 2.9
C = 0.7

You react the elements to form the substances AB, AC, and BC.

- What type of substance is AB? What type of bonds are present? Explain your answer.

- What type of substance is AC? What type of bonds are present? Explain your answer.

- What type of substance is BC? What type of bonds are present? Explain your answer.

Answer 1

#AB

Electronegativity difference=3.3-2.9=0.4.

• It's a covalent bond.
• Gaseous or solid substance.

#AC

Electronegativity difference=3.3-0.7=2.6

• Its an ionic bond.
• Solid substance.

#BC

Electronegativity difference=2.9-0.7=2.3

• It's an ionic bond
• Solid substance
