Electrons and Atomic Structure

Front

What happens to an electron's energy level as it moves further away from the nucleus in the Bohr model?

Back

The higher its energy level.

Front

Who is best associated with the statement, 'electrons orbit the nucleus in specific energy levels'?

Back

Niels Bohr.

Front

Which model of the atom is best associated with Quantum Mechanics?

Back

Quantum Mechanics.

Front

Who proposed that 'the atom has a solid nucleus at its center'?

Back

Ernest Rutherford.

Front

What is energy?

Back

The ability to do work.

Front

What is the significance of the Bohr model in atomic structure?

Back

It introduced the idea of quantized energy levels for electrons.

Front

What did Ernest Rutherford's gold foil experiment demonstrate?

Back

The existence of a dense, positively charged nucleus in the atom.

Front

What is the main difference between the Bohr model and the Quantum Mechanical model of the atom?

Back

The Bohr model describes electrons in fixed orbits, while the Quantum Mechanical model describes electron positions in terms of probabilities.

Front

What is an electron cloud?

Back

A region around the nucleus where electrons are likely to be found, according to Quantum Mechanics.

Front

Define atomic number.

Back

The number of protons in the nucleus of an atom, which determines the element's identity.
