Magnesium has an atomic number 12 and an atomic mass number 24 how many electrons are in its third energy shell?
Magnesium has 12 protons and electrons and its electronic configuration is 2.8.2, therefor it has 2 electrons in its 3rd energy level or elcectron outer shell
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?
Why does magnesium have an ionization number of 2?
Magnesium is in group 2 of the Periodic table, and so has 2 electrons in its outermost energy level. Therefore, its outermost energy level is full once 2 electrons are removed, and so it has an ionisation number of 2
Does argon has the same number of electrons in its outer shell as magnesium metal?
No. Argon has eight electrons in its outer shell and magnesium has two electrons in its outer shell.
What can be said of the number of electrons of the one element can have?
A neutral atom of an element will have the same number of electrons as protons (atomic number). For example, the element magnesium has the atomic number 12, which means that a neutral magnesium atom will have 12 protons and 12 electrons.
What is the number of electrons in the 1st energy level of magnesium?
All elements except hydrogen have two electrons in the first energy level.

What is the number of electrons and oxidation number of magnesium?
Singl atom has 12 electrons. Oxidation number of it is +2.
How electrons does magnesium have?
12 electrons in total as the atomic number of magnesium is 12
What is the valency number of magnesium?
Valency is not a word... but if you want to know the number of valence electrons that Magnesium has, it is 2. Magnesium's atomic number is 12.
Describe the correct arrangement of electrons in an atom that contains twelve electrons.?
The atomic number is equivalent to an atom's total number of electrons. The element with 12 electrons in magnesium. It has two valence electrons and in group 2.
What on the periodic table has 12 electrons?
Magnesium, Mg, atom number 12, 12 protons and 12 electrons.
How many valence electrons does a neutral magnesium atom have?
12, the same as the number of protons indicated by magnesium having an atomic number of 12.
What is the atomic number of magnesium what does the number tell you?
The atomic number of magnesium is 12. The atomic number is equivalent to the number of protons and electrons in the atom.
Does argon has the same number of electrons in its outer shell as magnesium metal?
No. Argon has eight electrons in its outer shell and magnesium has two electrons in its outer shell.
