2 electrons are in magnesiums last energy level
How many electrons are in the third energy level of magnesium atom?
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.
How many orbits are in the element magnesium?
The element magnesium has 3 orbits because it is in the third row down from the top of the periodic table.
How many electron levels in magnesium?
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.
How many electrons are in the second energy level of magnesium?
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.
How many numbers of electrons are on the outer ring of magnesium?
Magnesium has 2 electrons on its outer energy level.
How many electrons are in its outer energy level for Magnesium?
