5.2 Study Guide

Question 1

What happens during Polar Covalent Bonds?

Answer 1

One atom is significantly higher in electronegativity than the other and the high atom pulls a lot harder for the lower atom’s electrons. The relationship is unequal.

Question 2

What happens during Nonpolar Covalent Bonds?

Answer 2

Both atoms have the same electronegativity and their relationship is equal. Equal pull on one another.

Question 3

What happens during Covalent Bonds?

Answer 3

Valence Electrons are shared or fought over therefore bonding the two together.

Question 4

What happens during Ionic Bonds?

Answer 4

One atom has significantly higher electronegativity and instead of sharing like in covalent bonds the high atom just takes the electron it needs to have an outer ring. Therefore bonding the two atoms.

Question 5

Differentiate between a polar and nonpolar covalent bond?

Answer 5

Nonpolar has equal electronegativity while polar relationships do not they have opposite endpoints.

Question 6

When given two atoms, what type of bond will form between them and why?

Answer 6

It depends on the electronegativity of the atoms involved. If one atom has significantly higher electronegativity and instead of sharing like in covalent bonds the high atom just takes the electron it needs to have an outer ring. Therefore bonding the two atoms. Or valence electrons are shared/fought over therefore bonding the two together.

Question 7

Explain how electronegativity determines what type of bond two atoms will form?

Answer 7

One way to determine the type of bond that forms between two elements is to compare the electronegativities of the elements. Large differences in electronegativity result in ionic bonds, while smaller differences result in covalent bonds.
