The number of protons in an element is always the same as the atomic number, which is 12 in this case. In a neutral atom (no charge), the number of electrons equals the number of protons, so it will be 12 electrons also. However, the number of neutrons will vary depending on the isotope (atoms of the same element with different numbers of neutrons). There are three isotopes of Magnesium, 24Mg, 25Mg, 26Mg, having 12, 13, and 14 neutrons respectively (12 is the most abundant).
See link below for more information on Magnesium, as well as the related question below that will show you how to find the number of each subatomic particle in any atom.
What else can I help you with?
Is an atom with 12 protons 12 neutrons and 12 electrons an isotope?
No, an atom with 12 protons, 12 neutrons, and 12 electrons is not an isotope. Isotopes are atoms of the same element with different numbers of neutrons. Since this atom has the same number of protons, neutrons, and electrons, it is a stable and neutral atom of magnesium.
Element whose neutral atoms have 12 electrons?
Atoms of Magnesium have 12 electrons. Elements in the periodic table with a neutral charge must all have a number of electrons equal to the number of protons in the nucleus. Since Magnesium has an atomic number of 12, and the atomic number is also known as the PROTON number, then it must also have 12 electrons to balance out the charge. Magnesium has an atomic mass of about 24 - the other 12 units of mass being made up of neutrons.
What are the number of protrons and electrons for magnesium ion?
the number of proton=the number of electron= 12
A neutral atom must have the same number of neutrons and electron true or false?
FALSE!!!! A neutral atom must have the same number of protons and electrons. The number of neutrons can vary, to form isotopes. When the number of protons and electrons are different, they are no longer atoms but IONS. If we take hydrogen as an example, it forms three isotopes. #1 ; protium ; 1 proton, 0 neutrons and 1 electrons #2 ; deuterium ; 1 proton , 1 neutron and 1 electron #3 ; tritium ; 1 proton , 2 neutrons and 1 electron Notice the protons and electrons are the same number, but the number of neutrons varies, between isotopes.
How many neutrons protons and electron are in the following elements manganese magnesium Argon Potassium Gold Hydrogen Fluorine Silicon Boron Bromine?
Manganese: 25 protons, 30 neutrons, 25 electrons. Magnesium: 12 protons, 12 neutrons, 12 electrons. Argon: 18 protons, 22 neutrons, 18 electrons. Potassium: 19 protons, 20 neutrons, 19 electrons. Gold: 79 protons, 118 neutrons, 79 electrons. Hydrogen: 1 proton, 0 neutrons, 1 electron. Fluorine: 9 protons, 10 neutrons, 9 electrons. Silicon: 14 protons, 14 neutrons, 14 electrons. Boron: 5 protons, 6 neutrons, 5 electrons. Bromine: 35 protons, 45 neutrons, 35 electrons.
Why are electrons number the same as neutrons number?
They are NOT. The number of electrons and the number of neutrons are not linked at all - for instance, an atom of Hydrogen has one proton and one electron and NO neutrons.
Is an atom with 12 protons 12 neutrons and 12 electrons an isotope?
No, an atom with 12 protons, 12 neutrons, and 12 electrons is not an isotope. Isotopes are atoms of the same element with different numbers of neutrons. Since this atom has the same number of protons, neutrons, and electrons, it is a stable and neutral atom of magnesium.
What is the number of protons neutrons and electrons does helium have?
1 Proton and 1 electron but no neutrons.
How many proton and electrons does the element magnesium have?
Magnesium has an atomic number of 12, therefore it has 12 protons, and therefore 12 electrons.
What element has 12 electrons and 12 protons?
Magnesium (Mg) Bottom number is the proton number. Top number is mass number = Protons + Neutrons Therefore no. of neutrons = Top - Bottom number In atom proton number = electron number. However if it was an ion of Mg e.g. Mg+ then its electron number would be 13 and its proton number would be 12. Hope this will help. P.S I gave you the extra info as you will now be able to work out WHY! :D

What are the number of protrons and electrons for magnesium ion?
the number of proton=the number of electron= 12
What is the proton neutrons and electrons of hydrogen?
1 proton and 1 neutron
Where are proton neutrons electrons found on the nucleus?
Electrons are around the nucleus. Protons and neutrons are in the middle.
Atomic mass is number of protons added to the number of neutrons. Why is number of electrons not included in it?
Because electrons are very light particles and do not effect the mass, if proton and neutrons are elephant then electrons are ants , how ants effect the mass and weight of elephant ?

There are only one proton and electron. But it contains 2 neutrons.
