Unit 1 Experience 3 - Atomic Emission & the Bohr Model

Front

Atomic Emission Spectrum

Back

The pattern formed when light emitted by an element is separated into the different wavelengths it contains

Front

Why is atomic emission spectrum called the elemental fingerprints of an element?

Back

No two elements have the same atomic emission spectrum similar to how no two people have the same fingerprints.

Front

The fixed energies an electron can have.

Back

Energy Levels

Front

The amount of energy required to move an electron from one energy level to another.

Back

Quantum

Front

The lowest possible energy level.

Back

Ground State

Front

Excited State

Back

When electrons gain energy, they move to higher energy levels.

Front

A simplified picture of an atom.

Back

Bohr Model

Front

Which energy state will have the lowest/shortest wavelengths and why?

Back

The excited state(s) because there is more energy in motion (kinetic).

Front

Which energy state will have the longest/biggest wavelengths and why?

Back

The ground state because energy is being stored (potential).

Front

Which transition requires the greatest input of energy?

Back

Ground state to excited state. This is like moving from energy level 1 to energy level 3.
