Science Chemistry
I'm filling out those missing value charts with atomic numbers, protons, charge, etc. The info i've been given is protons (4), neutrons (5), electrons (2). I got 4 for th eatomic number, and 2 for the charge. The problem is the atomic mass. Once I got 6, the other time I got 9. Which is correct? Thanks for explaining.
The atomic mass number is equal to the sum of the (number of protons) + ( number of neutrons). Which of your two numbers is equal to that?
