What is a Bohr Model?

Back

A Bohr Model is a diagram that represents the structure of an atom, showing electrons in specific energy levels or orbits around the nucleus.

Front

What does the mass number of an atom represent?

Back

The mass number of an atom represents the total number of protons and neutrons in its nucleus.

Front

How do you determine the number of protons in an atom?

Back

The number of protons in an atom is equal to its atomic number, which is unique to each element.

What is the atomic number of Lithium?

Back

The atomic number of Lithium is 3.

Front

What is the significance of energy levels in a Bohr Model?

Back

Energy levels in a Bohr Model indicate the specific distances from the nucleus where electrons can exist without radiating energy.

Front

How many electrons can the first energy level hold?

Back

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

Front

What element has the atomic number 18?

Back

The element with atomic number 18 is Argon.

Front

What is the electron configuration of Carbon?

Back

The electron configuration of Carbon is 1s² 2s² 2p².

Front

What is the relationship between mass number and isotopes?

Back

Isotopes are variants of an element that have the same number of protons but different mass numbers due to varying numbers of neutrons.

Front

What is the mass number of Chlorine?

Back

The mass number of Chlorine is typically 35.
