Question

The periodic table of elements tells you how many __________ each atom has. (Choose all that apply)


colors


protons


neutrons


electrons

Answer 1

The periodic table of elements tells you how many **protons** each atom has.

Additionally, with an understanding of the atomic number (which equals the number of protons), you can also infer the number of **electrons** in a neutral atom, since they are equal in number to protons.

The number of **neutrons** is not directly indicated on the periodic table, as it depends on the isotope of the element, which can vary.

So, the correct answers would be **protons** and **electrons** (for neutral atoms).
