Final answer:
If the nucleus of an atom was the size of a period, the entire atom would be approximately the size of a football stadium. Atoms are mostly empty space with a small, dense nucleus in the center ensuring electrons stay in orbit.
Step-by-step explanation:
If we use a scale where the nucleus of an atom is the size of a period at the end of a sentence, then the entire atom would be approximately the size of a football stadium. Atoms are mostly empty space with a tiny, densely packed nucleus at the center. This is due to the electromagnetic forces between the positively charged protons in the nucleus and the negatively charged electrons buzzing around the nucleus at relatively large distances. This model of the atom is known as the Rutherford Model.
