• nucleus
• neutron
• electron
• proton

Multiple Choice

What subatomic particles can you find in the nucleus?

• neutrons and electrons
• electrons and protons
• protons and electrons
• protons and neutrons

Multiple Choice

Where are electrons located in atom?

• nucleus
• proton shells
• neutron shells
• Electron cloud

Atomic Structure

Protons- Positive Charge
Neutrons- Neutral Charge
Electrons- Negative Charge

The Nucleus is in the center of the atom

Protons and Neutrons are located in the nucleus
Electrons orbit around the atom in the electron cloud

*Remember there are always the same amount of protons and electrons because atoms have a neutral charge.

How do you find the number of neutrons in the atomic mass?

Math Response

Calculate the number of neutrons in this element

Show your work!!!!!!!!

___ -___ = ___

Type answer here

Correct Answer: 16-8=8

Deg^°

Rad

To find the protons and electrons, look at the atomic number

To find the neutrons, round to the nearest whole number on the atomic mass, then subtract atomic number from the atomic mass.

On this element, we round up the atomic mass to 16, subtract the atomic number 8, and get the number of neutrons is 8.

​16-8=8
