What is the maximum number of f orbitals that are possible?

7 Orbitals

Explanation:

The number of subshell present are s, p, d, and f

The number of orbitals in each are as follows -

The s subshell - 1 orbital consists of 2 electrons The p subshell - 3 orbitals consists of 6 electrons The d subshell - 5 orbitals consists of 10 electrons The f subshell - 7 orbitals consists of 14 electrons

The number of orbitals can be calculated by the degeneracy,  2 l + 1 , where l denoted is angular momentum quantum number that determines the shape of an orbital. For s, p, d, and f the angular momentum quantum number is 0, 1, 2 3 respectively.

So, maximum number of f orbitals that are possible can be calculated as -

2 ×  l + 1  =  2  × 3  + 1  =  7

Neptune is the eighth planet from the sun. it was the first planet to get its existence predicted by  mathematical calculations  before it was actually seen through a telescope on sept. 23, 1846. irregularities in the orbit of  uranus  led french astronomer alexis bouvard to suggest that the gravitational pull from another celestial body might be responsible. german astronomer johann galle then relied on subsequent calculations to   spot neptune via telescope. previously, astronomer galileo galilei sketched the planet, but he mistook it for a star due to its slow motion. in accordance with all the other planets seen in the sky, this new world was given a name from greek and roman mythology — neptune, the roman god of the sea.
