Chem 511 Unit 3 Review: Atomic Structure

Front

What is the atomic structure of Chlorine?

Back

Chlorine has 17 protons, 18 neutrons, and 17 electrons. It is represented in the Bohr model with 3 energy levels.

Front

What is a Lewis Dot Structure?

Back

A Lewis Dot Structure is a diagram that shows the bonding between atoms of a molecule and the lone pairs of electrons that may exist in the molecule.

Front

How many valence electrons does Carbon have?

Back

Carbon has 4 valence electrons.

Front

What is the net charge of an atom with 7 protons, 8 neutrons, and 7 electrons?

Back

The net charge is 0, as the number of protons equals the number of electrons.

Front

Which of the following is not a colorless, odorless gas: Helium, Radon, Iodine, Krypton?

Back

Iodine is not a colorless, odorless gas; it is a purple solid at room temperature.

Front

What is the significance of protons in an atom?

Back

Protons determine the atomic number and identity of an element.

Front

What is the role of neutrons in an atom?

Back

Neutrons contribute to the atomic mass and stability of the nucleus but do not affect the charge.

Front

What is the charge of an electron?

Back

Electrons have a negative charge.

Front

What is the maximum number of electrons in the first energy level of an atom?

Back

The first energy level can hold a maximum of 2 electrons.

Front

What is the Bohr model of the atom?

Back

The Bohr model depicts electrons orbiting the nucleus in fixed paths or energy levels.
