Bohr Models

Front

What is a Bohr model?

Back

A Bohr model is a diagram that represents the arrangement of electrons in an atom, showing the energy levels or shells around the nucleus.

Front

What are energy shells?

Back

Energy shells are regions around the nucleus of an atom where electrons are likely to be found, each shell corresponds to a specific energy level.

Front

How many electrons can the first energy shell hold?

Back

The first energy shell can hold a maximum of 2 electrons.

Front

How many electrons can the second energy shell hold?

Back

The second energy shell can hold a maximum of 8 electrons.

Front

How many electrons can the third energy shell hold?

Back

The third energy shell can hold a maximum of 18 electrons, but typically holds 8 in stable configurations.

Front

What is electron configuration?

Back

Electron configuration is the distribution of electrons in an atom's energy levels or shells.

What is the electron configuration for Neon?

Back

The electron configuration for Neon is 2-8.

Front

What is the significance of the atomic number?

Back

The atomic number indicates the number of protons in an atom's nucleus and determines the element's identity.
