Atomic Structure/Bohr Models

Front

What are valence electrons?

Back

Valence electrons are the electrons in the outermost shell of an atom that are involved in forming bonds with other atoms.

How many valence electrons does carbon have?

Back

4

Front

What is the mass number of an atom?

Back

The mass number is the total number of protons and neutrons in an atom's nucleus.

Front

If an atom has 10 protons and 15 neutrons, what is its mass number?

Back

25

Front

What is the atomic number of an element?

Back

The atomic number is the number of protons in the nucleus of an atom, which determines the element's identity.

Front

How many protons does sulfur have?

Back

16

Front

What is a Bohr model?

Back

A Bohr model is a diagram that represents the structure of an atom, showing electrons in circular orbits around the nucleus.

Front

What element is represented in this Bohr Model? (Assuming a model with 3 electrons in the first shell and 1 in the second)

Back

Lithium

Front

What are subatomic particles?

Back

Subatomic particles are the particles that make up an atom, including protons, neutrons, and electrons.

Front

What charge do electrons have?

Back

Electrons have a negative charge.
