There are 2 energy levels in a Carbon atom. The first energy level consists of '1s' orbital, and the second energy level consists of the '2s' orbital and the '2p' orbital.
In a neon atom, the first energy level or orbit can hold up to 2 electrons, the second energy level can hold up to 8 electrons, and the third energy level can hold up to 8 electrons. Therefore, a neon atom would have 2 electrons in the first energy level, 8 electrons in the second energy level, and 8 electrons in the third energy level, totaling 18 electrons.
An atom in which an electron has moved to a higher energy level is in an excited state. This can happen when the electron absorbs energy from its surroundings, such as from light or heat. The electron will eventually return to its original energy level, releasing the absorbed energy as light.
The atom will have 3 energy levels. The first energy level can hold up to 2 electrons, the second level can hold up to 8 electrons, and the third level can hold the remaining electron.
well, on the periodic table of elements a chlorine atom has 17 electrons, usually the first level holds up to two electrons and the second level holds up to 8. so if my figuring is correct there should be fifteen electrons on the second energy level.
the largest number of electrons an atom of helium can have is 2, because it is in the first period, which means it can only have one energy level, which has a maximum capacity of two electrons
In the ground state, the outermost principle energy level of an argon atom is the third energy level. This energy level contains the 3s and 3p sublevels. The 3s sublevel can hold up to 2 electrons, while the 3p sublevel can hold up to 6 electrons.
K (potassium) has 2 electrons the the 1st energy level, 8 each in the 2nd and 3rd, and 1 electron in the 4th.
The first principle energy level of the hydrogen atom contains only one orbital, which is called the 1s orbital. This orbital can hold up to 2 electrons.
When a sodium atom is heated and gives off a line spectrum, the outermost electron absorbs energy and gets excited to a higher energy level. As the electron returns to its original energy level, it releases this energy in the form of light, creating the characteristic line spectrum of sodium.
An atom of oxygen has 2 energy levels that are occupied - the first energy level (K shell) can hold up to 2 electrons, and the second energy level (L shell) can hold up to 6 electrons. Oxygen has a total of 8 electrons.
The electrons move up to a higher energy level.
