https://session.masteringchemistry.com/myct/itemView?offset-next&assignmentProblemID-92272947; Homework #s Energy Levels in Atoms Energy Levels in Atoms Learning Goal: To understand the energy levels in atoms. In an atom, each electron has a fixed energy known as its energy level. For example, n = 1, n = 2, and n = 3 are energy levels. With certain number of orbitals. Part A What is the maximum number of electrons that can be contained in the first, second, third, and fourth energy levels, respectively? Express your answer as integers separated by commas. Hints Submit My Answers Give Up Part B Enter the maximum number of electrons in each type of sublevel (s. p, d, and f, respectively) Express your answer as integers separated by commas. Hints Submit My Answers Give Up Energy levels and electromagnetic radiation An electron in an atom can be raised to a higher energy level by absorbing energy if the electron falls to a lower energy level, it releases the Part c Rank the following kinds of electromagnetic radiation in order of decreasing wavelength Rank the types of electromagnetic radiation by their wavelength from longest to shortest. To rank items as equivalent overlap

Explanation / Answer

1. No of electrons in the shell = 2n2 ,  n= shell number

1st shell= 2(1)2 = 2

2nd shell = 2(2)2 = 8

3rd shell = 2(3)2 = 18

4th shell = 2(4)2 = 32

2. No of electrons in subshell = No. of subshells x 2(maximum capacity of subshell)

s - orbital = 1x 2 = 2, s orbital is only one type.

p - orbital = 3 x 2 = 6, p orbital has 3 subshells

D - orbital = 5 x 2 = 10, d orbital has 5 subshells

f - orbital = 7 x 2 = 14 , f orbital has 7 subshells
