Review for Atomic Structure Quiz - Rebecca Barry | Laabri

1

The Atomic Number is also known as what?

Number of Protons

Number of Neutrons

Number of Electrons

Mass Number

1

If the number of protons and the number of electrons in an atom are EQUAL, the atom is said to be what?

Positively Charged

Neutral

Negatively Charged

An Isotope

1

What is the correct equation to calculate the Mass Number of an atom?

Mass Number= Atomic Number + Number of Neutrons

Mass Number = Atomic Mass + Number of Neutrons

Mass Number = Electrons + Neutrons

Mass Number = Charge + Neutrons

1

What is the correct equation to calculate the number of neutrons?

Number of Neutrons = Mass Number - Atomic Number

Number of Neutrons = Mass Number + Atomic Number

Number of Neutrons = Atomic Mass + Atomic Number

Number of Neutrons = Electrons + Charge

1

What is the correct equation to calculation the charge of an atom?

Charge = Protons + Electrons

Charge = Protons - Electrons

Charge = Protons + Neutrons

Charge = Protons - Neutrons
