What particles are found in the nucleus?

• Protons

• Protons and electrons

• Protons and neutrons

• Electrons

What particles are found outside of the nucleus?

• Protons

• Protons and Electrons

• Protons and Neutrons

• Electrons

Where is the atomic number found on an element square?

• top of the square

• bottom of the square

• middle of the square

• what is an atomic number?

Where is the atomic mass(mass number) found on the element square?

• at the top of the element square

• at the bottom of the element square

• in the middle of the element square

• now there is an atomic mass too? what is that?

How do you calculate the number of protons in an element?

• Look at the atomic number-it is the same number

• look at the atomic mass-it is the same number

• Atomic mass-Atomic number

• Ugh, now we have to do math in science?!?
