Nearly all sodium found in nature has a mass number of 23, so it is 23Na. There are traces in nature of 22Na, which is radioactive and has a half life of 2.6 years. In addition, there are 20 known synthetic isotopes of sodium (two are metastable and have the same mass numbers as two others), with mass numbers ranging from 18 to 37.

What is the atomic mass number of sodium?
Sodium is a meta element. Atomic mass of it is 23.
What is the atomic number and atomic mass of Sodium?
The atomic number of Sodium is 11, which means it has 11 protons in its nucleus. The atomic mass of Sodium is approximately 23 amu (atomic mass units), which is the weighted average of all the isotopes of Sodium found in nature.
What is the atomic mass number of an sodium that contains 12 neutrons?
The atomic mass number of an atom is the sum of its protons and neutrons. Sodium (Na) has an atomic number of 11, meaning it has 11 protons. If it contains 12 neutrons, its atomic mass number would be 11 protons + 12 neutrons = 23. Therefore, the atomic mass number of this sodium atom is 23.
How many neutron in sodium element?
Subtract the atomic # from the atomic mass. Atomic number = number of Protons. Atomic mass = total nucleons (Protons + Neutrons).Atomic # = 11 and Atomic Mass = 23. So 23-11 = 12 Neutrons.
What is the Atomic number of Sodium-23?
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

The atomic number of Sodium is 11, which means it has 11 protons in its nucleus. The atomic mass of Sodium is approximately 23 amu (atomic mass units), which is the weighted average of all the isotopes of Sodium found in nature.
What is the explanation of the atomic mass of Sodium?
Sodium is a meta element. Atomic mass of it is 23. Atomic number of it is 11.
How many neutron in sodium element?
Subtract the atomic # from the atomic mass. Atomic number = number of Protons. Atomic mass = total nucleons (Protons + Neutrons).Atomic # = 11 and Atomic Mass = 23. So 23-11 = 12 Neutrons.
What is the Atomic number of Sodium-23?
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
