Bohr Models, Isotopes, & Ions Review

Front

What is a Bohr model?

Back

A Bohr model is a representation of an atom that shows electrons orbiting the nucleus in defined paths or energy levels.

Front

What does the atomic number represent?

Back

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

Front

What is an isotope?

Back

An isotope is a variant of a chemical element that has the same number of protons but a different number of neutrons.

Front

How do you determine the number of neutrons in an isotope?

Back

To find the number of neutrons, subtract the atomic number from the mass number (Neutrons = Mass Number - Atomic Number).

Front

What is the charge of a neutral atom?

Back

A neutral atom has no charge, meaning the number of protons equals the number of electrons.

Front

What is a cation?

Back

A cation is a positively charged ion that occurs when an atom loses one or more electrons.

Front

What is an anion?

Back

An anion is a negatively charged ion that occurs when an atom gains one or more electrons.

Front

What is the mass number of an atom?

Back

The mass number is the total number of protons and neutrons in the nucleus of an atom.

Front

How many protons does Carbon have?

Back

Carbon has 6 protons.

Front

What is the charge of a carbon ion with 4 electrons?

Back

The charge of a carbon ion with 4 electrons is -2, as it has lost 2 protons.
