• 10.811

What is matter made of?

• Matter is made from small particles called Atoms

• Atoms are made from smaller particles called Subatomic Particles.

• 3 Subatomic particles are Protons, Neutrons, and Electrons

Multiple Select

What are the 3 Subatomic Particles?

(Choose all that apply)

• nucleus

• neutrons

• protons

• electrons

• isotopes

Protons

Charge of a proton is Positive

Location of a proton is in Nucleus

Size of a proton is 1 AMU

Multiple Choice

Which statement is correct?

• Protons are located outside the nucleus and have a positive charge.

• Protons are located inside the nucleus and have a positive charge.

• Protons are located outside the nucleus and have no charge.

Neutrons

Charge of the neutron is Neutral

(No Charge)

Location of the neutron is in the Nucleus

Size of the neutron is 1 AMU

Multiple Choice

Which statement is correct?

• Neutrons are located outside the nucleus and have a positive charge.

• Neutrons are located inside the nucleus and have a positive charge.

• Neutrons are located inside the nucleus and have no charge.

Electrons

Charge of the electrons in Negative

Location of an electron is Outside the Nucleus

Size of an electron is so small that it adds no mass to the atom .

Multiple Select

Check all that are correct about an electron.

• Electrons are positive

• Electrons are negative

• Electrons are inside the nucleus

• Electrons are outside the nucleus

• Electrons are very small

Nucleus

• Nucleus contains protons and neutrons

• Nucleus has a positive charge

• Nucleus contains the mass of the atom

• Nucleus is surrounded by the electron cloud

Electron Cloud

• Surrounds the nucleus

• Contains electrons that are on energy shells

• Has a negative charge

Multiple Choice

True or False: The electron cloud contains electrons and has a negative charge.

• True

• False

Energy Levels (Shells)

• Energy levels/shells make up the electron cloud

• Each energy level/shells holds a certain amount of electrons

• We study the first 3 levels/shells

288 Rule

• 2 electrons on first energy level/shells

• 8 electrons on second energy level/shells

• 8 electrons on third energy level/shells

Atomic Mass/ Mass Number

• Protons and Neutrons contribute to the mass of the atom

• Electrons DO NOT contribute to the mass of the atom BECAUSE they are TOO SMALL

• PROTONS + NEUTRONS = Atomic Mass/ Mass Number

Neutral Atoms

Neutral atoms have to have the SAME number of protons and electrons because the (+) and (-) charges will cancel out.
