Exploring Atomic Structure and Spectra

Front

Bohr model's concept of energy levels in an atom

Back

Electrons orbit the nucleus in fixed energy levels.

Front

What happens when an electron in an atom moves from a higher energy level to a lower energy level?

Back

The atom emits a photon.

Front

Which of the following statements about emission spectra is true?

Back

Emission spectra are unique to each element and consist of discrete lines.

Front

Explain why the energy levels in an atom are quantized according to the Bohr model.

Back

Because electrons can only exist at specific energy levels.

Front

Back

The electron emits a photon.

Front

How can the emission spectra be used to identify elements?

Back

By matching the unique line spectra of the element to known spectra.

Front

Describe the process of photon emission in terms of electron transitions.

Back

Electrons release energy and move to a lower energy level, emitting a photon.

Front

Why do different elements have different emission spectra?

Back

Because they have different arrangements of electrons and energy levels.

Front

What is the significance of the ground state in the context of atomic energy levels?

Back

It is the most stable and lowest energy state of an atom.

Front

Explain how electron transitions between energy levels result in the emission of light.

Back

Electrons release energy as light when they fall to lower energy levels.
