∙ 6y agoMagnesium is atomic number 12. Thus, it has 12 protons and 12 electrons in the neutral state. If it becomes an ion, it loses 2 electrons to become Mg^2+. The Mg^2+ ion has 12 protons and 10 electrons.

What are the number of protrons and electrons for magnesium ion?
the number of proton=the number of electron= 12
Is an atoms number of protons is always the same as its number of valence electrons?
For neutral atoms, the electron number is always the same as the proton number.For ions, charged atoms, the proton number is different than the electron number by the charge (e.g. a hydrogen ion, H(+1) has 1 proton and 0 electrons, 1 more proton than electrons).
What does the charge on the magnesium ion have to do with the number of valence electrons that an atom of magnesium has?
The charge on a magnesium ion is +2. This indicates that the two valence electrons present in a magnesium atom have been donated to form one or two anions of some other element.
How many protons and electrons are in a nitrogen ion -3?
3! Electron number always equals the Proton number!
When the proton number and electron number are unequal the atom or molecule what?
has a charge which can be positive (excess protons) or negative (excess electrons). ... becomes an ion - positive ion if deficient in electrons, negative with an excess of electrons.
What are the number of protrons and electrons for magnesium ion?
the number of proton=the number of electron= 12
What do you call an atom where the number of electrons is different from the number of protons?
An ion. If electrons are in excess over proton then it is negative ion. And if less then positive ion
What is the number of electrons and oxidation number of magnesium?
Singl atom has 12 electrons. Oxidation number of it is +2.
Infer Magnesium and sodium atoms are about the same size How does the size of a magnesium ion with a 2 charge compare with that of a sodium ion with a single charge?
The sodium ion will be larger. Because magnesium has one more proton than sodium, its nuclei pull harder on the electrons, reducing the ion's radius. This means that the magnesium ion is smaller.
What is the charge on a magnesium ion that has ten electrons?
The charge on a magnesium ion with 10 electrons (Mg2+) is +2.
How many electrons does the most common ion of magnesium Mg have?
The atomic number of magnesium is 12. The cation loses two electrons for 10.
Is an atoms number of protons is always the same as its number of valence electrons?
For neutral atoms, the electron number is always the same as the proton number.For ions, charged atoms, the proton number is different than the electron number by the charge (e.g. a hydrogen ion, H(+1) has 1 proton and 0 electrons, 1 more proton than electrons).

The charge on a magnesium ion is +2. This indicates that the two valence electrons present in a magnesium atom have been donated to form one or two anions of some other element.
How many protons and electrons are in a nitrogen ion -3?
3! Electron number always equals the Proton number!
What is the total number of electrons in a Mg2 positive ion?
The Magnesium atom will lose 2 of its electrons to become a Magnesium ion with 10 electrons. (Mg2+) How many electrons does a magnesium ion have? How many electrons does a fluoride ion have? How many electrons does a fluoride ion have?
How does the size of a magnesium ion with a 2 positive charge compare with that of a sodium ion with a single positive charge?
A magnesium ion will be smaller because there will be a greater Zeff on the electrons in the magnesium ion due to a greater number of protons in the nucleus.
When the proton number and electron number are unequal the atom or molecule what?
has a charge which can be positive (excess protons) or negative (excess electrons). ... becomes an ion - positive ion if deficient in electrons, negative with an excess of electrons.
