Sodium is a metal element. Atomic Mass of it is 23.
where was sodium found and when
.Cause is a metal that come in lots of food
B. a soudium-potassium pump.
Sodium is a element it's a pure substance
yes
yes. an element on the peridioc table. Na 11 protons and 23.0 electrons it is a solid
no because if you put the sodium chlorider in the sea it will kill the fish and it will not be nice
Soudium acetate/Sodium ethanoate, water and carbon dioxide.
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 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
