3 levels (shells) which contain 2,8,2 electrons.
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
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?
An atom of magnesium has 3 energy levels - the first energy level can hold up to 2 electrons, the second can hold up to 8 electrons, and the third can hold up to 18 electrons.
Magnesium has 3 electron orbits. The first orbit can hold up to 2 electrons, the second orbit can hold up to 8 electrons, and the third orbit can hold up to 8 electrons.
no. of electrons to fill an energy level = 2n2. = 2x32 = 18
Magnesium has two electrons in its first energy level, eight electrons in its second energy level, and two electrons in its third energy level, for a total of 12 electrons.
2 electrons are in magnesiums last energy level
There are 2 electrons in the first energy level, 8 electrons in the second energy level, and 2 electrons in the third energy level of a magnesium atom, as it has an atomic number of 12 with electron configuration 2-8-2.
The element magnesium has 3 orbits because it is in the third row down from the top of the periodic table.
Magnesium has three electron levels, also known as energy levels or shells. The electron configuration of magnesium is 2-8-2, indicating that it has two electrons in its first energy level, eight electrons in its second energy level, and two electrons in its third energy level.
There are 8 electrons in the second energy level of magnesium. This can be determined because magnesium has an atomic number of 12, meaning it has 12 electrons in total. The first energy level is filled with 2 electrons, leaving 10 electrons to distribute in the remaining energy levels, with 8 of those in the second level.
Magnesium has 2 electrons on its outer energy level.
There are 2 outer shell electrons in Magnesium. Remember, it's in the "s" orbital, which can only accomodate 2 electrons.
In the second energy level of an atom, there can be a maximum of 8 electrons. Magnesium has 12 electrons in total, with 2 electrons in the first energy level and 8 electrons in the second energy level.
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
A neutral atom of magnesium has 2 electrons in its outermost energy level. Magnesium has a total of 12 electrons, with 2 electrons in the first energy level and 8 electrons in the second energy level. The outermost energy level is the second energy level in the case of magnesium.
Beryllium and magnesium have two electrons in their outermost energy level, as do all Group 2 elements.
