What defines the atomic number?
Think about how elements are identified.
True or False: Isobars have the same number of protons.
Remember the difference in their definitions.
Consider the isotopes of carbon, specifically carbon-12 and carbon-14. What are their atomic numbers, mass numbers, and how do they differ in terms of neutrons?
Apply the relationship between protons, neutrons, and mass number.
Imagine an atom with 20 protons and 20 neutrons. If it were found to have an electron configuration of 2-8-10, describe the atomic number, mass number, and its possible uses.
Check the periodic table for its applications in real life.
