FAQs

Question: What is the difference between atomic number and mass number?
Answer: The atomic number is the number of protons in an atom, while the mass number is the total number of protons and neutrons.

Question: How do I determine the electron configuration of an element?
Answer: The electron configuration can be determined using the Aufbau principle, Hund's rule, and the Pauli exclusion principle to fill the orbitals in order of increasing energy.
