Every isotope of magnesium has 12 electrons.
Magnesium has 12 protons and electrons and 12, 13 or 14 neutrons, depending on the isotope.
12
The atomic number of Mg (and not written as mg) is 12. So there are 12 protons and 12 electrons Note: Mg is the symbol for the element magnesium mg generally stands for milli grams
It an atom has 12 electrons and is neutral, then it must be Mg (magnesium), and magnesium has 2 valence electrons which would be used in bonding.
The atomic number of magnesium is 12. The cation loses two electrons for 10.
Magnesium has 12 protons and electrons and 12, 13 or 14 neutrons, depending on the isotope.
The ion Mg(2+) has 12 protons, 10 electrons and 12, 13 0r 14 neutrons depending on the isotope.

Magnesium is a metal element. There are 12 electrons in a single atom.
Magnesium's atomic number is 12. Thus, neutral magnesium would have 12 electrons. Mg2+ therefore has 2 less electrons, or 10.
Any atom of magnesium will have 12 protons.Neutral atoms of Mg-24 will have 12 neutrons and 12 electrons. Mg-25 has 13 neutrons and Mg-26 has 14 neutrons. A magnesium ion will have either 10 or 11 electrons.
Atom Mg-26 in the ground state has 2 valence electrons. Magnesium (Mg) has an atomic number of 12, so it has 12 electrons in total. In the ground state, the electron configuration is [Ne] 3s2, which means it has 2 electrons in the outermost shell (valence electrons).
Magnersium is a non metal element. There are 12 electrons in a single atom.
The atomic number of Mg (and not written as mg) is 12. So there are 12 protons and 12 electrons Note: Mg is the symbol for the element magnesium mg generally stands for milli grams
