What is the atomic number of magnesium- 28?
The atomic number of Magnesium is 12.
What is the atomic number of Mg?
The atomic number of Mg (Magnesium) is 12.
What the atomic mass and the mass number of Mg?
The atomic number of magnesium is 12 and the mass number is 24.305 use the Periodic Table it gives you all the info you need :D
What elements have the atomic number 12 and atomic mass 8?
There is no element with an atomic number of 12 and an atomic mass of 8. Atomic number corresponds to the number of protons in an atom, while atomic mass is the sum of protons and neutrons. The atomic number of an element cannot be smaller than its atomic mass.
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.

What metal has an atomic number 12?
Mg- Magnesium
If an Atom has an atomic number of 12 What is the atomic number?
Atomic number depends on the number of protons and it doesn't matter how many neutrons there are in that case. Neutrons only contribute to the atomic weight. The atomic number is the same as any other atom of carbon: 6.
What is the atomic number for an abundant element with mass number 12?
The element with mass number 12 is carbon. The atomic number for carbon is 6.
How do you tell how many neutrons are in an atom with the atomic number of 12?
To find the number of neutrons in an atom with an atomic number of 12 (which is the number of protons), you would subtract the atomic number from the atomic mass number. The atomic mass number is the sum of the protons and neutrons in the atom. For an atom with an atomic number of 12, the number of neutrons can be calculated by subtracting 12 from the atomic mass number given for that specific atom.
An atom that has twelve protons in its nucleus has an atomic number of?
An atom with twelve protons in its nucleus has an atomic number of 12. The atomic number represents the number of protons in an atom's nucleus, which determines the element. In this case, the element with 12 protons is magnesium.
What the atomic number for an abundant element with mass number 12?
The atomic number is 6.
What the atomic mass and the mass number of Mg?
The atomic number of magnesium is 12 and the mass number is 24.305 use the Periodic Table it gives you all the info you need :D
What elements have the atomic number 12 and atomic mass 8?
There is no element with an atomic number of 12 and an atomic mass of 8. Atomic number corresponds to the number of protons in an atom, while atomic mass is the sum of protons and neutrons. The atomic number of an element cannot be smaller than its atomic mass.
What is the number of neutrons in an atom with atomic number 12 and mass number 22?
Number of neutrons = Mass number - Atomic number = 22 - 12 = 10
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.
