Stable isotopes are 204, 206, 207, and 208. Average is 207.2.

0 is the charge of the isotope because it has 19 electrons and 19 protons but 20 neutrons. Even if the number of neutrons changes it has no effect on the charge of the atom so 19- and 19+ leads to a neutral or no charge. 0 is the answer
The priest leads the Eucharistic prayers, the people at the Mass , as well as the priest off the sacrifice up to God.
The mass number of Am-241 is 241; each isotope has another mass number.
Atomic mass is the number of protons in an atom mass number is the number of protons plus neutrons in an atom the number of neutrons would equal the mass number minus the atomic number.
yes mass can be a number
the mass number of sodium is 23
The atomic weight of uranium is 238,02891(3) atomic mass units. The mass number is the total number of nucleons (protons an neutrons) in the nucleus; the mass number is different for each isotope: 234U: mass number 234 235U: mass number 235 238U: mass number 238
Mass number minus the atomic number equals the number of neutrons. Mass number is the number of particles in an atom that have significant mass. Electrons are assigned a value of 0 since the mass is so much smaller than protons and neutrons. Protons and neutrons are similar in mass and are assigned mass number of 1. The formula for calculating atomic mass atomic mass = # protons + # neutrons.
Mass number = Number of protons + number of neutrons
We can find Atomic Mass and mass number in chemical elements. Atomic mass is about weight of the atom. Mass number is about total of neutrons and protons.
