Subtract the proton number or atomic number (11) from the nucleon number or the Atomic Mass (23) and you get the number of neutrons = '''12'''.

How many neutrons does sodium have in its nucleus?
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
How do you determine neutrons in an atom of sodium-20?
the atomic mass
An atom of sodium has 11 protons 11 electrons and 12 neutrons What is its atomic number and its mass number?
The atomic number of an atom is the number of protons it has, so in this case, the atom of sodium has an atomic number of 11. The mass number of an atom is the sum of its protons and neutrons, so the mass number of this sodium atom is 23 (11 protons + 12 neutrons).
If a sodium atom has 11 protons and 12 neutrons what is its mass number?
The mass number of an atom is the sum of its protons and neutrons. In this case, the mass number of the sodium atom with 11 protons and 12 neutrons would be 23.
How many nuetrons in a sodium atom?
there are 11.99 neutrons in an atom of sodium
How many neutrons are in an atom of sodium with mass number 23?
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).
What is the atomic mass number of an atom of sodium that contains 12 neutrons?
The atomic mass number of an atom is the sum of its protons and neutrons. Sodium typically has 11 protons, so if the atom has 12 neutrons, the atomic mass number would be 23 (11 protons + 12 neutrons).
What do we do to determine the number of neutrons in a atom?
atomic number
How do protons neutrons and electrons determine the properties of an atom?
the number of electron can determin if the element is very reactive or not eg sodium has 11 electrons. sodium is very reactive because of its eletron arangement.
What does the number of neutrons determine?
The number of neutrons in an atom determines the isotope of the element. Isotopes of an element have the same number of protons but differing numbers of neutrons. This affects the stability and nuclear properties of the atom.
If the sodium atom contains 11 electrons 11 protons and 12 neutrons what is the mass number of sodium?
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.
What characteristic of an atom is NOT used to determine the number of neutrons in an atom?
The characteristic of an atom that is not used to determine the number of neutrons is its atomic number. The atomic number indicates the number of protons in an atom, while the number of neutrons is derived from the difference between the atomic mass (which is the total number of protons and neutrons) and the atomic number. Therefore, only the atomic mass and the atomic number are needed to calculate the number of neutrons.
