The first energy level can contain 2 electrons. The second energy level can contain 8 electrons. The third energy level can contain 18 electrons.
The maximum number of electrons that can be found in the first energy level (or inner level) of an element is 2 electrons. This is because the first energy level only has one subshell, which can accommodate a maximum of 2 electrons.
At energy level n=1, the total number of electrons that could be found is 2, as the first energy level can hold a maximum of 2 electrons.
Two electrons can be housed in the first energy level.
Two (in the case of helium).
The first energy level can hold up to 2 electrons.
Valence electrons are found in the outermost energy level of an atom, also known as the highest principal energy level. These are the electrons involved in chemical bonding and determining the reactivity of an element.
Zinc has 2 electrons on its 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.
the first energy levels hold 2, 8, and 18 a total of 28 electrons
There are no noble gases in the first energy level. Noble gases are found in the last (highest) energy level of an atom. The first energy level can only hold a maximum of 2 electrons, while the noble gases have completely filled outermost energy levels.
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.
