U5 Molecular Geometry & IMF Practice Test

Front

Which types of compounds dissolve easily in water?

Back

Polar and Ionic compounds dissolve easily in water due to their ability to form hydrogen bonds with water molecules.

Front

What are the characteristics of metals?

Back

Metals are typically shiny, malleable, ductile, and good conductors of heat and electricity.

Front

What is a polar molecule?

Back

A polar molecule has a net dipole moment due to the presence of polar bonds, where electrons are shared unequally between atoms.

Front

What is electronegativity?

Back

Electronegativity is the measure of an atom's ability to attract and hold onto electrons in a covalent bond.

Front

According to the octet rule, how many valence electrons do most elements need?

Back

Most elements need 8 valence electrons to achieve a stable electron configuration.

Front

What is the difference between polar and nonpolar molecules?

Back

Polar molecules have a partial positive charge on one end and a partial negative charge on the other, while nonpolar molecules have an even distribution of charge.

Front

What is the significance of hydrogen bonding in water?

Back

Hydrogen bonding in water leads to its unique properties, such as high surface tension, high specific heat, and the ability to dissolve many substances.

Front

What is the octet rule?

Back

The octet rule states that atoms tend to gain, lose, or share electrons to achieve a full outer shell of 8 electrons.

Front

What are ionic compounds?

Back

Ionic compounds are formed when electrons are transferred from one atom to another, resulting in the formation of positively and negatively charged ions.

Front

What is a covalent bond?

Back

A covalent bond is formed when two atoms share one or more pairs of electrons.
