Multiple Select

How are these atomic models the same? What do all of them have in common?

Choose all correct answers.

• They all have protons

• They all have a nucleus

• They all have neutrons

• They all have electrons

• They all have the same number of protons, neutrons, and electrons.

​How are these models different?

​As the atomic mass increases, the size of the atom increases.

An element with an atomic mass of 10 is much smaller than an element with an atomic mass of 120.

Hydrogen has an atomic mass of 1.

Carbon has an atomic mass of 12.

It would take 12 atoms of hydrogen to equal 1 atom of carbon.
