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.
Sodium has an atomic mass of 23 and an atomic number of 11 so the number of neutrons must be?
Sodium does have an atomic number of 11, and if the isotope's atomic mass is 23, the atom would have 11 protons (the atomic number) and 12 neutrons (the atomic mass minus the atomic number). The atom would have 11 electrons, and when ionized it would lose one and take on a charge of +1.
Na-23 has 12 neutrons what is its atomic number?
11
When Na-23 has 12 neutrons what is its atomic number?
11
How many neutrons and protons does a neutral atom of sodium with an atomic mass number of 23 have?
Every sodium atom has 11 protons, the atomic number of sodium. The isotope with mass number 23 has (23 - 11) or 12 neutrons, because the mass number of an isotope is defined as the sum of the numbers of protons and neutrons in the isotope.
What atom has an atomic number of 23 12 neutrons and how many electrons?
Vanadium has an atomic no. of 23 and mass number of 51. But it has 28 neutrons and 23 electrons
Sodium has an atomic mass of 23 and an atomic number of 11 so the number of neutrons must be?
Sodium does have an atomic number of 11, and if the isotope's atomic mass is 23, the atom would have 11 protons (the atomic number) and 12 neutrons (the atomic mass minus the atomic number). The atom would have 11 electrons, and when ionized it would lose one and take on a charge of +1.
How do you the get neutrons?
Neutrons in an atom Equation Atomic Weight - Atomic Number = The neutrons of an element Round for the final answer Example: Sodium (Na) Atomic Number: 11 Atomic Weight: 23 23-11= 12 neutrons so therefore sodium has 12 neutrons
Na-23 has 12 neutrons what is its atomic number?
11
When Na-23 has 12 neutrons what is its atomic number?
11
An element has of atomic number of 11 and atomic weight of 23 what is the number of neutrons in the nucleus of this atom?
23 - 11 = 12
How many neutrons are in a neon 23 atom?
It depends on which isotope you are talking about. The stable form of sodium is 23Na, which has 11 protons and 12 neutrons. Isotopes of sodium range from 18Na, with 7 neutrons, to 37Na, with 26 neutrons.
What is the atomic number of Na 23?
atomic weight - protons = neutrons, Na-23 has an atomic weight of 23 amu, and 11 protons so 23-11=12 neutrons
How many neutrons and protons does a neutral atom of sodium with an atomic mass number of 23 have?
Every sodium atom has 11 protons, the atomic number of sodium. The isotope with mass number 23 has (23 - 11) or 12 neutrons, because the mass number of an isotope is defined as the sum of the numbers of protons and neutrons in the isotope.
An atom has 11 protons and 12 neutrons Its atomic mass is?
The atomic mass of an atom with 11 protons and 12 neutrons is calculated by adding the number of protons and neutrons together. In this case, the atomic mass would be 11 (protons) + 12 (neutrons) = 23 atomic mass units.
What is atomic number of 12 neutron?
12 neutrons has nothing to do with atomic number. Atomic number is the number of protons. You might mean sodium. Sodium has an atomic number of 11, and an atomic mass that rounds to 23, so 23 -11 = 12 neutrons in some isotopes of sodium. but some atoms of magnesium atomic number 12 also have 12 neutrons with a mass number of 24, and probably some other element, but those are all I can think of now.
How do you determine the number of neutrons for a sodium atom?
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'''.
