Topic Summary: Atomic Structure
Sample Flashcards
What are isotopes?
Isotopes are atoms of the same element (same number of protons) with different numbers of neutrons. This means they have the same atomic number but different mass numbers.
Why are atoms electrically neutral?
Atoms are electrically neutral because the number of protons (positive charges) equals the number of electrons (negative charges). The positive and negative charges cancel out.
Sample Questions
What does the atomic number of an element tell you?
Describe the structure of an atom. Include the location and charge of the three main subatomic particles.
