Chemistry Review 1st Semester SPLP

Front

Why do atoms bond?

Back

To have a full valence shell.

Front

When the volume of a gas increases, what happens to the pressure?

Back

The pressure will decrease.

Front

What does VSEPR stand for?

Back

Valence Shell Electron Pair Repulsion.

Front

Covalent bonding occurs between which types of elements?

Back

Nonmetal and nonmetal.

Front

How many significant figures are in the number 100000000?

Back

1.

Front

What is the octet rule?

Back

Atoms tend to bond in such a way that they have eight electrons in their valence shell.

Front

What is the difference between ionic and covalent bonds?

Back

Ionic bonds involve the transfer of electrons, while covalent bonds involve the sharing of electrons.

Front

What is a molecule?

Back

A molecule is a group of two or more atoms bonded together.

Front

Define the term 'valence electrons'.

Back

Valence electrons are the electrons in the outermost shell of an atom that are involved in chemical bonding.

Front

What is the ideal gas law?

Back

The ideal gas law is PV=nRT, where P is pressure, V is volume, n is the number of moles, R is the gas constant, and T is temperature.
