There is no atom with that mass. Even hydrogen, the lightest element, has an atomic mass of 1.674 x 10 ^ -21 g
Isotopes.
To convert from atomic weight to grams, multiply by 1.6605402e-24. For instance, the atomic weight of the most common isotope of Oxygen is 15.9994. In grams, that would be 15.9994 * 1.6605402e-24 = 2.656764688e-23 g.
Since n + p = m, it follows that neutrons = 54 - 24 = 30,because number of protons (p) is the atomic number (34)! That's how the periodic table is organized.
1/(6.02214 x 1023) = 1.66054*10-24 molesC-atoms= 1 C-atom
Chromium (symbol: Cr; atomic number: 24) is in the fourth period, or row, of the periodic table.
Looking at a periodic table, you see Al is number 13. It has 13 protons in the nucleus,so to have a total mass number of 24, it must have 11 nuetrons. Mass number = # protons + # nuetrons
the atomic mass is found mostly in the nucleus since most of the atom's space is empty space and electrons weigh about 0.005 relative to a neutron which weighs about 1.675 multiplied times 10-24 grams
The atomic number of magnesium is 12 and the mass number is 24.305 use the Periodic Table it gives you all the info you need :D
I don't have a periodic table, but round its atomic mass to a whole number and subtract the amount of protons which equal the atomic number. So if the atomic mass is 24 and the atomic number is 12, 24-12=12.- example
