Front

What is one difference between the atomic structures of Carbon-12 and Carbon-13?

Back

Different number of neutrons.

Front

Define an isotope.

Back

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

Front

What is the atomic number of an element?

Back

The atomic number is the number of protons in the nucleus of an atom.

Front

Explain the concept of atomic mass.

Back

Atomic mass is the weighted average mass of an element's isotopes, measured in atomic mass units (amu).

Front

What is the relationship between wavelength and energy in electromagnetic waves?

Back

Longer wavelengths correspond to lower energy, while shorter wavelengths correspond to higher energy.

Front

What is the mass of a neutron compared to a proton?

Back

A neutron has a mass similar to that of a proton, but slightly greater.
