2024 Honors Unit 3 Review: Atomic Theory

Front

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 calculate the number of neutrons in an atom?

Back

To find the number of neutrons, subtract the atomic number (number of protons) from the atomic mass (rounded to the nearest whole number).

Front

What is the definition of frequency in terms of waves?

Back

Frequency is the number of waves that pass a given point in one second, measured in Hertz (Hz).

Front

Which color of light has the longest wavelength?

Back

Red light has the longest wavelength in the visible spectrum.

Front

What is the relationship between wavelength and frequency?

Back

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

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 many protons does Neon have?

Back

Neon has 10 protons.

Front

What is the mass number of an atom?

Back

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

Front

How many neutrons are in a Sodium-24 isotope?

Back

Sodium-24 has 13 neutrons.

Front

What is the definition of amplitude in wave physics?

Back

Amplitude is the maximum extent of a wave's oscillation, measured from the rest position.
