Atomic Theory, Atomic Math, & Bohr Models

Front

What is the Bohr model of the atom?

Back

The Bohr model is a representation of the atom where electrons orbit the nucleus in defined paths or shells, similar to planets orbiting the sun.

Front

Where are protons and neutrons located in an atom?

Back

Protons and neutrons are found in the nucleus of an atom.

Front

What is the significance of the atomic number?

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

Isotopes are variants of a particular chemical element that have the same number of protons but different numbers of neutrons.

Front

Which type of electromagnetic radiation has the highest energy?

Back

Gamma rays have the shortest wavelength and therefore the highest frequency and energy.

Front

What term did Democritus coin to describe the smallest unit of matter?

Back

Democritus coined the term 'atom' to describe the smallest indivisible unit of matter.

Front

What color of light has the shortest wavelength?

Back

Violet light has the shortest wavelength in the visible spectrum.

Front

What is the relationship between wavelength and frequency?

Back

Wavelength and frequency are inversely related; as wavelength decreases, frequency increases.

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 do you calculate the number of neutrons in an atom?

Back

To calculate the number of neutrons, subtract the atomic number (number of protons) from the mass number.
