Q

What happens with electrons during ionic, polar covalent, and non polar covalent bonds?

A

Electrons are shared differently in ionic and covalent bonds. Covalent bonds can be non-polar or polar and react to electrostatic charges. Ionic bonds are due to electrostatic attractive forces between their positive and negative charged ions.

Q

Differentiate between a polar and nonpolar covalent bond

A

Polar covalent bonds result when electrons are unequally shared between atoms, while nonpolar covalent bonds result when electrons are more equally shared between atoms.

Q

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

A

Covalent, because it holds two atoms together as a molecule.

Q

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

A

In general, large differences in electronegativity result in ionic bonds, while smaller differences result in covalent bonds.

Q

Comparing how ionic and covalent substances dissolve in water

A

When ionic compounds dissolve in water they go through a process called dissociation, splitting into the ions that make them up. However, when you place covalent compounds in water, they typically do not dissolve but form a layer on top of the water.
