Covalent Bond

Question 0

Bond length

Answer 0

Distance between two bonded atoms at their minimum potential energy

Question 1

Molecular orbital

Answer 1

The overlapping space between two atoms where the shared electrons orbit

Question 2

Bond energy

Answer 2

Energy required to break a chemical bond. It relates to the energy released when forming the bond

Question 3

Bond strength is _____ proportional to bond energy

Answer 3

Directly ( +bond energy +bond strength / -bond energy -bond strength)

Question 4

What is a covalent bond?

Answer 4

When two atoms that have similar electronegativity values and are close in the periodic table bond.

Question 5

Nonpolar covalent bond

Answer 5

When atoms share electrons equally
Similar or the same electronegativity values
Mostly diatomic molecules (C2)

Question 6

Polar covalent bond

Answer 6

When the shared electrons are not equally shared. When one atom has higher electronegativity than the other.
One atom tends to be slightly positive and other slightly negative.
