Maximum number of orbitals in an energy level (n2)
| Principal Energy Level (n) | sublevels | total electrons |
|---|---|---|
| 2 | 2s 2p | 8 |
| 3 | 3s 3p 3d | 18 |
| 4 | 4s 4p 4d 4f | 32 |

Which element has a total of 5 valence electrons present in the fifth energy level?
antimony
There are five electrons in the outermost energy level, so it has 5 valence electrons. The element is antimony, a metalloid. 2.
What element has 7 valence electrons and 5 energy levels?
Chlorine is a member of the group of atoms on the periodic table called the halogens. They are all one electron away from the noble gases which are highly stable compounds. Chlorine has 7 valence shell electrons, 2 in the 3s orbital and 5 in the 3p orbital.
Which element has 5 electrons in highest energy level?
Nitrogen, with its 5 outermost electrons, interacts with hydrogen atoms in a ratio of 1:3, forming ammonia (NH3). Oxygen and sulfur, with their 6 outermost electrons react with hydrogen to form water (H2O) and hydrogen sulfide (H2S).
What comes after 5s in electron configuration?
The 4d sublevel is filled next, after the 5s sublevel.
What is the 5th energy level?
The fifth energy level contains: 5s (which holds 2 electrons), 5p (which holds 6), 5d (holds 10), and 5f (holds 14) for a total of 32 electrons.
How many orbitals are in the 5th energy level?
25
l=0 to l=(n−1) . For each of the orbital states we have a different number of total orbitals which is increasing as the azimuthal number increases. Hence, the total number of orbitals in the fifth energy level is 25.
Which is element has 3 energy levels and 5 valence?
Educators go through a rigorous application process, and every answer they submit is reviewed by our in-house editorial team. The element that has three energy levels and five valence electrons in its outer level is phophorous, atomic number 15. Each row or period of the periodic table corresponds to a principal energy level.
What makes up the third period of an element?
All elements in the third period have three electron energy levels and have their valence electrons in the third level. Orbitals are sub-levels within the principal energy level, so the word orbital isn’t used interchangeably with energy level.
How many valence electrons does chlorine have?
Chlorine has 7 valence electrons in its third energy level. Based on this, does chlorine tend to lose its electrons? Why or why not?Note, the third energy level can hold up to 18 electrons (4…
How many valence electrons does phosphorous have?
Group 1 elements have one valence election, Group 2 elements have two, Group 13 (also known as IIIA) have three, Group 14 (IVA) have four, Group 15 (VA) have five and so on. Phosphorous is the 5th element from the left in the third period so it has five valence electrons.
