Determination of atomic number and mass number (Chemistry Form2)
Every element in the universe has its own identity card and scientists have found a way to read it. The atomic number tells you exactly how many protons are inside an atom, making it unique to that element. The mass number tells you how heavy it is. Put them together, write them in nuclide notation, and you can unlock the complete picture of any atom: its protons, neutrons, and electrons. Today you'll learn to read and write every atom's identity code! Let's decode the language of elements!
