there are two electrons in the first energy level of every element except for hydrogen which only has one electron in the first energy level.
Two electrons can be housed in the first energy level.
The first energy level can hold up to 2 electrons.
Zinc has 2 electrons on its first energy level.
Two electrons can be housed in the first energy level.
Lithium has a total of 3 electrons. The first energy level of an atom can hold a maximum of 2 electrons, so the first energy level of lithium will have 2 electrons.
Argon has 2 electrons in the first energy level, 8 electrons in the second energy level, and 8 electrons in the third energy level.
The first energy level can take a maximum of two electrons.
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.
Oxygen has 2 electrons in its first energy level.
An argon atom has 2 electrons in its first energy level, 8 electrons in its second energy level, and 8 electrons in its third energy level.
there are 2 electrons in potassium's innermost energy level
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.
