how many electrons are in Mg

The atomic number of magnesium (Mg) is 12, which means it has 12 protons in its nucleus. In a neutral atom, the number of electrons is the same as the number of protons. Therefore, there are also 12 electrons in magnesium.

The element symbol 'Mg' represents the element magnesium.

To determine the number of electrons in an atom of magnesium, we can consult the periodic table. Magnesium is located in Group 2 (Group IIA) of the periodic table, which indicates that it has 2 valence electrons.

However, to determine the total number of electrons in a neutral magnesium atom, we need to consider its atomic number. The atomic number of magnesium is 12.

Since atoms are electrically neutral, the number of electrons in an atom is equal to its atomic number. Therefore, a neutral magnesium atom contains 12 electrons.

To determine how many electrons are in an atom of magnesium (Mg), we need to look at its atomic number. The atomic number of an element represents the number of protons found in its nucleus and also the number of electrons that orbit around the nucleus of a neutral atom.

The atomic number of magnesium is 12. Therefore, in a neutral atom of magnesium, there are also 12 electrons.
