Questions & Answers

Q: What is the atomic number?

The atomic number is the number of protons in the nucleus of an atom, and it determines the element.

Q: How is the mass number calculated?

The mass number is the sum of protons and neutrons in the nucleus of an atom.

Q: What is an isotope?

Isotopes are atoms that have the same number of protons but different numbers of neutrons.

Q: How is the isotope symbol written?

The isotope symbol includes the element symbol, atomic number, and mass number.
