Atomic Structure, EMS, and Trends 1.0

Front

What is the mass number?

Back

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

Front

What determines the color of visible light?

Back

The wavelength determines the color of visible light.

Front

What does the atomic number represent?

Back

The atomic number represents the number of protons in an element.

Front

How many protons does indium have?

Back

Indium has 49 protons.

Front

What is the difference between atomic mass and mass number?

Back

Atomic mass is the weighted average mass of an element's isotopes, while mass number is the total number of protons and neutrons.

Front

What are valence electrons?

Back

Valence electrons are the electrons in the outermost shell of an atom that are involved in chemical bonding.

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

What is the significance of the periodic table?

Back

The periodic table organizes elements based on their atomic number, electron configuration, and recurring chemical properties.

Front

What is the relationship between wavelength and frequency?

Back

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

Front

What is an electron configuration?

Back

An electron configuration is the distribution of electrons in an atom's electron shells and subshells.
