Electrons in Atoms Review

Front

What is the symbol for wavelength?

Back

The symbol for wavelength is lambda (λ).

Front

What does 'h' represent in physics?

Back

In physics, 'h' represents Planck's Constant.

Front

What principle states that electrons fill the lowest energy orbitals first?

Back

The Aufbau Principle states that electrons fill the lowest energy orbitals/levels first before occupying higher energy levels.

Front

What happens when electrons move from higher to lower energy levels?

Back

When electrons move from higher to lower energy levels, emission spectra (bright line spectra) are created.

Front

What is Hund's Rule?

Back

Hund's Rule states that electrons will occupy degenerate orbitals singly before pairing up.

Front

What is the significance of the Aufbau Principle in electron configuration?

Back

The Aufbau Principle is significant because it helps predict the electron configuration of an atom based on energy levels.

Front

What is the relationship between energy levels and electron configuration?

Back

Energy levels determine the arrangement of electrons in an atom, influencing its chemical properties.

Front

What is the formula for calculating the energy of a photon?

Back

The energy of a photon can be calculated using the formula E = hν, where E is energy, h is Planck's constant, and ν is frequency.

Front

What is the difference between absorption and emission spectra?

Back

Absorption spectra occur when electrons absorb energy and move to higher energy levels, while emission spectra occur when electrons release energy and fall to lower energy levels.

Front

What is the shape of s, p, d, and f orbitals?

Back

s orbitals are spherical, p orbitals are dumbbell-shaped, d orbitals have complex shapes, and f orbitals are even more complex.
