Bohr Models

Front

What is the Bohr model of the atom?

Back

The Bohr model is a theory that describes the atom as having a small, positively charged nucleus surrounded by electrons that travel in circular orbits around the nucleus, with specific energy levels.

What is the atomic number of an element?

Back

The atomic number is the number of protons in the nucleus of an atom, which determines the element's identity.

Front

How do you determine the mass number of an atom?

Back

The mass number is determined by adding the number of protons and neutrons in the nucleus of an atom.

What is the charge of a neutron?

Back

A neutron has no charge (it is neutral).

Front

What is the charge of an electron?

Back

An electron has a negative charge.

Front

How many electrons can fit in the first energy level of an atom?

Back

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

Front

How many electrons can fit in the second energy level of an atom?

Back

The second energy level can hold a maximum of 8 electrons.

Front

What is the significance of the number of protons in an atom?

Back

The number of protons determines the element's identity and its position on the periodic table.
