Web4f= (4+3)= 7. 5p= (5+1) = 6. Solution: 4s<4d<5p<4f. Even though 4d and 5p have the same "n + l " value, the subshell with the lowest "n" value will have the lower energy level. Notice that even though the 5p subshell has an n=5 value, it has a lower energy level than 4f because overall "n + l " is lower for 5p than for 4f. WebThe shell closest to the nucleus (first shell) has 2 dots representing the 2 electrons in 1s, while the outermost shell (2s) has 1 electron. Figure 2. 6.1 Shell diagram of lithium (Li) …
