Counting Numbers of Protons, Neutrons, and Electrons

What is a positive particle in an atom?

• Protons

• Neutrons

• Electrons

• nucleus

What is the neutral particle in an atom

• protons

• neutrons

• electrons

• nucleus

What is the negative particle in an atom?

• proton

• neutron

• electron

• nucleus

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?!?

How do you calculate the number of electrons in an atom?

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

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

• Atomic mass-Atomic number

• Oh geesh...really?

How do you calculate the number of neutrons?

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

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

• atomic mass-atomic number

• Neutrons too?!? Oh good grief!
