An atom of sodium with mass number 23 has 12 neutrons. This can be calculated by subtracting the atomic number (which is 11 for sodium) from the mass number (which is 23).
12 neutrons are in the element sodium.
Atoms of the same element usually have the same number of protons but differ slightly in the number of neutrons. The number of neutrons are usually about the number of protons so it can be estimated as so. For example, there are two relatively common isotopes of sodium: sodium 22 and sodium 23, where the number is the total number of protons and neutrons. Sodium 22 has 11 neutrons and sodium 23 has 12 neutrons but the sodium atom has 11 protons. For further information, look up isotopes.
The mass number of an atom is the sum of its protons and neutrons. In this case, sodium has 11 protons and 12 neutrons, so the mass number is 11 + 12 = 23.
Sodium has 11 protons and 11 electrons. The number of neutrons in a sodium atom can vary depending on the isotope, but the most common isotope (sodium-23) has 12 neutrons.
12 neutrons
The number of neutrons in an atom is calculated by subtracting the atomic number from the mass number. Sodium has an atomic number of 11. So, for an isotope of sodium with a mass number of 25, the number of neutrons would be 14 (25 - 11).
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
Sodium has 11 electrons and protons; the number of neutrons is specific for each isotope. Number of neutrons in a sodium isotope = Mass number - 11
Because atoms can be isotopes or ions, protons are the only stable identifier for an element (Sodium can have more or less than normal number of electrons or neutrons and still be sodium). Sodium has 11 protons.
An atom of sodium with mass number 23 has 12 neutrons. This can be calculated by subtracting the atomic number (which is 11 for sodium) from the mass number (which is 23).
In Sodium there are 1 amu of protons and neutrons. There are also 11 protons and 11 electrons. There are 11 neutrons in Sodium 22.
