What is the relationship between the period number and the energy level of the f-orbitals?

Answer 1

The number of each period correspond to the outermost energy level that contain electrons for elements in that period. Those in period 1 contain electron only in energy level 1 while those in period 2 contain electron in level 1 & 2. In period 3, electrons are found in level 1, 2, and 3 AN SO ON.....

Answer 2

In a period where the d orbitals are filling, their energy level is 1 less than the period number. For example, in period 4, the 3d orbitals fill from left to right starting with scandium in group 3.

Answer 3

A period determines which energy level the element is in. For instance, Carbon 6C is found in the Period 2, therefore is in the 2nd energy level, and in its electron configuration, no electrons fill past the 2nd energy level. [He]2s22p2.

Answer 4

The period number tells you the energy level of the valence electrons.
