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 electron. It is found within energy levels called orbits. They are denoted by K,L,M,N,O,......
Chlorine-35 has three full shells of electrons. It has two electrons in the first energy level, eight electrons in the second energy level, and seven electrons in the third energy level, making a total of 17 electrons.
Chloride is an ion, not an atom. It has 18 electrons which are 2, 8, 8 in the first three quantum levels respectively.
The first element with an electron in the second energy level is lithium. Lithium has three electrons, with two in the first energy level and one in the second energy level.
The three main components of an atom are protons, neutrons, and electrons. Protons and neutrons make up the nucleus at the center of the atom, while electrons orbit around the nucleus in energy levels.
the first energy levels hold 2, 8, and 18 a total of 28 electrons
Lithium is an atom that has three electrons. It has an electron configuration of 2-1, with two electrons in the first energy level and one electron in the second energy level.
Sulfur has three energy levels, which can accommodate up to 16 electrons. The first energy level can hold a maximum of 2 electrons, the second energy level can hold up to 8 electrons, and the third energy level can hold up to 6 electrons.

The electrons in the first energy level have lower energy than the electrons in the second energy level. Electrons closer to the nucleus have lower energy levels as they experience stronger electrostatic attraction. In this case, the electrons in the second energy level are higher in energy because they are further from the nucleus and experience weaker attraction.
Chlorine-35 has three full shells of electrons. It has two electrons in the first energy level, eight electrons in the second energy level, and seven electrons in the third energy level, making a total of 17 electrons.
The electronic structure of sulfur is 2-8-6, which means it has 16 electrons arranged in three energy levels - 2 electrons in the first energy level, 8 electrons in the second energy level, and 6 electrons in the third energy level.
2, 8, 8
Lithium has three electrons, two in the inner shell and a single one ouside that, so there are two energy levels. See the link below
