What is the name of the state when the electron gains energy and it may move to a higher energy level?

Back

Excited State

Front

Which transition will produce the spectrum line with the lowest wavelength in an atomic spectrum?

Back

Transition D produces the spectrum line with the lowest wavelength.

Front

What happens to energy when an electron moves further from the nucleus in a Hydrogen atom?

Back

Energy is absorbed because the electron moves further from the nucleus.

Front

What is the chemical formula for calcium carbonate?

Back

CaCO₃

Front

What can characteristic spectral lines of the atomic emission spectrum be used to identify?

Back

An element.

Front

What is the ground state of an electron?

Back

The lowest energy state of an electron in an atom.

Front

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

Back

Energy is inversely proportional to wavelength; as energy increases, wavelength decreases.

Front

What is the principle behind the emission spectrum of an element?

Back

Electrons transition between energy levels, emitting light at specific wavelengths.

Front

What is the significance of the atomic emission spectrum?

Back

It can be used to identify elements based on their unique spectral lines.

Front

What does it mean for an electron to be in a higher energy level?

Back

The electron has absorbed energy and is further from the nucleus.
