Atom Practical Review

Name the subatomic particles? Protons, Neutron, and Electrons.

What two subatomic particles belong in the nucleus? Protons and Neutrons

Which subatomic particle has a positive charge? Protons

Which subatomic particle has a negative charge? Electrons

Which subatomic particle has a neutral charge? Neutrons

Subatomic Particle Charges Positive Proton Neutral Neutron Negative Electron

Where are the electrons located? Outside the nucleus in the Electron Cloud.

What is the atomic number? The number of protons in the nucleus.

What is the atomic mass? The number of protons and neutrons in the nucleus.

How do we find/calculate the number of neutrons in an atom? Subtract the number of protons from the atomic mass. (#neutrons = mass - # protons)

How many electrons can go in the 1 st energy level in the electron cloud? 2

How many electrons can go in the 2 nd energy level in the electron cloud? 8
