Question 1
1.
The Atomic Number is also known as what?
Number of Protons
Number of Neutrons
Number of Electrons
Mass Number
Question 2
2.
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
Question 3
3.
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
Question 4
4.
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
Question 5
5.
What is the correct equation to calculation the charge of an atom?
Charge = Protons + Electrons
Charge = Protons - Electrons
Charge = Protons + Neutrons
Charge = Protons - Neutrons
