Question

An element belongs to 3rd period. The (n + 1) value of its outer most subshell is 4. How many orientations are there for the given subshell?

• A. 1
• B. 3
• C. 5
• D. 7

Answer 1

Answer:

B. 3

• The problem states the element belongs to the 3rd period. Therefore, the principal quantum number for its outermost shell is n = 3 • We are given that the (n + l) value of the outermost subshell is 4 • .Using the value of n we just identified:3 + l = 4 • l = 4 - 3 • l = 1is the p subshell. • the outermost subshell is 3p.
