1What is the size of an atom's radius?
- A0.01 nanometers
- B0.1 micrometers
- C0.1 nanometers
2What is that in meters?
- A1 x 10 (to the -10) m
- B1 x 10 (to the -1) m
- C1 x 10 (to the -11) m
3Where is the nucleus?
- AOn the left
- BIn the center
- CAt the bottom
4Which two are in the nucleus?
- AProtons and Electrons
- BElectrons and Neutrons
- CNeutrons and Protons
5What is the size of a nucleus' radius?
- A1 x 10 (to the -15) m
- B1 x 10 (to the -14) m
- C1 x 10 (to the -16) m
6Which is what of the radius of an atom?
- A1/1000
- B1/100000
- C1/10000
7What charge does the nucleus have?
- APositive
- BNegative
- CNeutral
8Why is the nucleus this charge?
- ABecause it contains protons
- BBecause it contains electrons
- CBecause it contains only neutrons
- DBecause it does not contain any sub atomic particles
9How much of the mass of the atom is concentrated in the nucleus?
- ANone
- BAlmost the whole mass
- CThe whole mass
- DBarely any
10What move around the nucleus?
- AElectrons
- BProtons
- CNeutrons
11And what do they move around in?
- AElectron cirlcles
- BElectron shells
- CProton shells
- DProton circles
- ENeutron shells
- FNeutron circles
12What is the charge of electrons?
- APostitive
- BNegative
- CNeutral
13Electrons are...
- ALarge but cover a small amount of space
- BTiny and cover a small amount of space
- CLarge and cover a lot of space
- DTiny but cover a lot of space
14Electrons have mass
- AVerdadero
- BFalso
15Label the following diagram of an atom with:
~ Electron
~ Proton
~ Neutron
~ Electron Shell
~ Nucleus
- AElectron
- BProton
- CNeutron
- DElectron Shell
- ENucleus
16Fill in the blanks using the drop downs with the correct answer to complete the table.
- A1
- BVery small
- C1
- DVery small
- E1
- FVery small

- H-1
- I0
- J+1
- K-1
- L0
- M+1
- N-1
- O0
17The [blank_start]volume[blank_end] of electron orbits determines the size of the atom.
- Avolume
18Atoms are [blank_start]neutral[blank_end] - they have [blank_start]no charge[blank_end] overall (unlike ions).
- Aneutral
- Bno charge
19This is because they have the [blank_start]same number[blank_end] of [blank_start]protons[blank_end] as [blank_start]electrons[blank_end].
- Asame number
- Bprotons
- Celectrons
20The [blank_start]charge[blank_end] on the electrons is the [blank_start]same[blank_end] size as the charge on the [blank_start]protons[blank_end], but [blank_start]opposite[blank_end] - so the charges [blank_start]cancel out[blank_end].
- Acharge
- Bsame
- Cprotons
- Dopposite
- Ecancel out
21In an ion, the number of protons [blank_start]doesn't equal[blank_end] the number of [blank_start]electrons[blank_end]. This means it has an [blank_start]overall charge[blank_end]. For example, an ion with a 2 - charge, has [blank_start]two more[blank_end] electrons than protons.
- Adoesn't equal
- Belectrons
- Coverall charge
- Dtwo more
