Mass number is the number of protons and neutrons in the nucleus of an atom.
Atomic number on the Periodic Table is the number of protons in the nucleus of an atom.
mass number - atomic number = number of neutrons
The atomic number of sodium is 11. Specified mass number is 23. Therefore,
23-11 = 12 neutrons
From the periodic table sodium's atomic number is 11.
The number of protons in sodium is 11. It is equal to its atomic number.
22.99 g
There are 12 neutrons in a Sodium atom. To determine the number of neutrons in a specific element's atom, find the number of protons (its atomic number, which in this case is 11) and subtract it from the mass number (the number below the symbol in a periodic table rounded which in this case is 23).Sodium23 has 12 neutrons.there are 12 neutrons in a sodium atom
Atomic number= number of protons. Hydrogen atomic number=1
The atomic number of fluorine is 9.The atomic number of sodium is 11.
The atomic number is equal to number of protons in the atomic nucleus.
Gold is a metal element. atomic number of it is 79.
There are 12 neutrons in a Sodium atom. To determine the number of neutrons in a specific element's atom, find the number of protons (its atomic number, which in this case is 11) and subtract it from the mass number (the number below the symbol in a periodic table rounded which in this case is 23).Sodium23 has 12 neutrons.there are 12 neutrons in a sodium atom
the answer is that it is called a atomic number.
The atomic number is equal to the number of the protons in the atomic nucleus.
Atomic weight in atomic mass units = the number of protons + the number of neutrons. The number of protons is your atomic number. Subtract that from the atomic weight for the number of neutrons.
this elemnt has an atomic number that is double the atomic number of silicon?
Subtract the atomic number from the atomic weight.
