Our expert Chemistry tutor, Jules took 2 minutes and 43 seconds to solve this problem. You can follow their steps in the video explanation above. So, these orbitals are one 3 s -orbital, three 3 p -orbitals and five 3 d -orbitals.

In chemistry, the principal energy level of an electron refers to the shell or orbital in which the electron is located relative to the atom’s nucleus. This level is denoted by the principal quantum number n. The first element in a period of the periodic table introduces a new principal energy level. The highest number of orbitals in the principal energy level three is FIVE.

The total possible occupying electrons in this orbital is 18 (10+6+2 from lower energy levels). Writing out the number of electrons in all the energy levels and sublevels of an atom produces the electron configuration of the atom. The third principal energy level has one s orbital, three p orbitals, and five d orbitals, which can each hold up to 10 electrons. The first principal energy level has one sublevel that contains one orbital, called the s orbital.

In this sense the third shell can hold a total of 18 electrons. So the third shell can be considered to hold 8 or 18 electrons but in total the third shell can hold 18 electrons. The third electron shell has #3# subshells, which are #3s#, #3p#, and #3d#. draw the alkane formed when 4,5,5-trimethyl-1-hexyne is treated with two equivalents of hbr. Dr. Helmenstine holds a Ph.D. in biomedical sciences and is a science writer, educator, and consultant. She has taught science courses at the high school, college, and graduate levels. 2) Orbitals are combined when bonds form between atoms in a molecule.

The next principal energy level contains one s orbital and three p orbitals. The set of three p orbitals can hold up to six electrons. Thus, the second principal energy level can hold up to eight electrons, two in the s orbital and six in the p orbital. In atomic theory and quantum mechanics, an atomic orbital is a mathematical function that describes the wave-like behavior of either one electron or a pair of electrons in an atom.
