What is the charge of a neutron

• Negative

• No charge

• Positive

• I don’t know

What is the mass of a proton or neutron

• No mass

• 1 amu

• Less than 1 amu

If an atom has 2 valence electrons in its first shell is the atom least reactive or most reactive?

• least reactive

• Neither

• least reactive and most reactive

• most reactive

What is the charge of a proton and electron

• Negative and no charge

• No charge and negative

• Positive and negative

• Both same charges

What is the number of protons or electrons on this atom and how do you know?

• 7, because of the atomic mass

• 3, because of the atomic number

• 10, because you add the atomic mass and atomic number together.
