Ans. Protons and neutrons are located in the nucleus of an atom, while electrons orbit around the nucleus in specific energy levels or shells.
3. What is the atomic number of an element and how is it related to the number of protons?
Ans. The atomic number of an element is the number of protons in the nucleus of an atom of that element. It is unique to each element and determines its chemical properties.
4. What is an isotope and how does it differ from a regular atom?
Ans. Isotopes are atoms of the same element that have the same number of protons but different numbers of neutrons. This results in variations in atomic mass for isotopes of the same element.
