Bohr’s Atomic Model

Front

What are the building blocks of matter?

Back

Atoms are the building blocks of matter that make up everything we encounter every day.

Front

What is the atomic number used for?

Back

The atomic number is used to determine the number of protons and electrons in an atom.

Front

How do you calculate the number of neutrons in an atom?

Back

Number of neutrons = Mass number - Atomic number.

Front

Who proposed the quantized shell model of the atom?

Back

Niels Bohr proposed the quantized shell model of the atom.

Front

What did Bohr's model explain about electrons?

Back

Bohr's model explained how electrons have stable orbits around the nucleus.

Front

What is the main feature of the Rutherford model?

Back

The Rutherford model had orbiting electrons moving around a massive nucleus.

Front

What concept did Sommerfeld introduce to Bohr's model?

Back

Sommerfeld introduced the concept of elliptical orbits.

Front

What are the three refinements in Bohr’s atom worked out by Sommerfeld?

Back

1. Introduction of elliptical orbits 2. Allowance for orbiting motion of electrons 3. Consideration of relativistic mass effects.

Front

What is the purpose of the educational links provided in the lesson?

Back

The educational links provide additional resources for learning about atomic models.

Front

What materials can be used to create a replica of atomic models?

Back

Plain cookies, candies, chocolates, sprinkles, creams, and fillings can be used to create replicas of atomic models.
