What is the maximum number of s orbitals found in a given electron shell? the maximum number of p orbitals? of d orbitals? of f orbitals? g?

The "s" sublevel has 1 orbital, with a maximum of 2 electrons.
The "p" sublevel has 3 orbitals, with a maximum of 6 electrons.
The "d" sublevel has 5 orbitals, with a maximum of 10 electrons.
The "f" sublevel has 7 orbitals, with a maximum of 14 electrons.
The "g" sublevel has 9 orbitals, with a maximum of 18 electrons.

Looking at this, you can tell that there's a pattern. After s, p, d, and f, the letters continue in alphabetical order. Every following letter has 2 more orbitals than the previous letter. The maximum number of electrons can be found by multiplying that orbital number by 2.

29.1-12=17.1the answer is this one

Copper, silver, aluminum, cobalt, chromium, mercury
