Atoms / Structure of Atoms 8th Grade Science

What is an Atom?

• The pure substance of an element made of subatomic particles

• Atoms are made of small molecules all tied together with string

• Atoms make up the subatomic particles of life

• Large particles that you can see on a microscope

Atomic Mass of an element contains what?

• Protons+Neutrons+Electrons=Atomic Mass

• Protons Only

• Protons + Neutrons

• Neutrons + Electrons

What does the Atomic Number of an Element tell us?

• How many Electrons are present in its atom

• How many Neutrons are present in its atom

• How many Protons are present in its atom

• How many AMU's are in the atom

What is the Mass of ONE Proton?

• 1 g (Gram)

• 1 Ug (Microgram)

• 1 Pg (Picogram)

• 1 AMU (Atomic Mass Unit)

What is the mass of ONE Neutron?

• 2 AMU (Atomic Mass Units)

• 1 AMU (Atomic Mass Unit)

• zero

• Same as an Electron

What is the Mass of ONE Electron?

• About Zero

• Same as Protons

• Same As Neutrons

• 1 AMU (Atomic Mass Units)

What are the Subatomic Particles?

• Protons

• Neutrons

• Electrons

• All of the above

What Electrical Charges do the Subatomic Particles have?

• Protons=(+) / Neutrons=(-) / Electrons= (Neutral)

• Protons=(-) / Neutrons=(Neutral) / Electrons= (+)

• Protons=(+) / Neutrons=(Neutral) / Electrons= (-)

Where are Protons Located?

• In the Middle

• In the Nucleus

• Same place as Neutrons

• All of the above

Where are Neutrons Located in the Atom?

• In the brain

• Same place as Electrons

• In the Nucleus

• In the Electron Cloud Orbitals
