Which type of orbitals are found in the principle enegery level n=3? a. s, db. s, p,d c. s, p d. s, p,fe. s, d,f

b. s,p,d

Explanation:

The type of orbitals found in the principal energy level n=3 is s, p and d orbitals.

Principal quantum number(n) denotes the energy level in which an orbital is located.

The principal quantum numbers takes values from n = 1, 2,3,4

For example, the orbitals found in the principal quantum number with a value of 1 is s.

For n = 2, we have s and p

For n = 3, it is given as s, p and d

For n = 4, we have s, p, d and f

idk what the question is about

answer: atomic mass was originally used to arrange elements on the periodic table, but is no longer used to organize the modern version.

explanation:

originally atomic mass was used to arrange elements on the periodic table from left to right in a row. each column then shows similar properties of elements of a group.

in modern periodic table, the atoms are arranged in increasing atomic number. as atomic number represents the number of protons in an atom which is unique for every atom.
