The atomic number and mass number are really important for understanding elements on the periodic table! Let’s break it down:
Atomic Number: This is just how many protons are in the center of an atom. For example, carbon has an atomic number of 6. This means carbon has 6 protons.
Mass Number: This tells us the total number of protons and neutrons in the atom’s center. For carbon, since it has 6 protons and usually 6 neutrons, the mass number is 6 + 6 = 12.
So, here’s a simple way to remember:
