Front

According to the Bohr Model, electrons are only found in specific orbits around the nucleus called _____________.

Back

Energy Levels

Front

What atom matches the electron configuration 1s² 2s² 2p⁶ 3s² 3p⁴?

Back

Sulfur

Front

Which state has higher energy: Ground State or Excited State?

Back

Excited State

Front

What happens during a line emission spectrum?

Back

Electron transition from higher to lower energy level.

Front

Define 'Energy Level' in the context of atomic structure.

Back

Energy levels are the fixed distances from the nucleus of an atom where electrons can be found.

Front

What is the significance of the ground state of an atom?

Back

The ground state is the lowest energy state of an atom, where electrons are in the closest possible orbits to the nucleus.

Front

Explain the term 'excited state' in atomic physics.

Back

An excited state occurs when an electron absorbs energy and jumps to a higher energy level.

Front

What is the relationship between electron transitions and light emission?

Back

When electrons transition from a higher energy level to a lower one, they emit light in the form of photons.

Front

What does the term 'line emission spectrum' refer to?

Back

A line emission spectrum is a series of specific wavelengths of emitted light from an atom, corresponding to electron transitions.
