Then, subtract the atomic number.
Answer in your notebook! 1. How do you find the atomic number? The atomic number is the number at the top of the box. 2. How do you find the atomic mass of the element? The atomic mass is the number at the bottom of the box. We usually round the atomic mass to the whole number. 3. How do you find the number of protons in the element? The number of protons is the same as the atomic number. 4. How do you find the number of neutrons in the element? The number of neutrons is the atomic mass (rounded to the nearest whole) minus the atomic number. 5. How do you find the number of electrons in the element? The number of electrons is the same number as the atomic number.
