Question

Statement I : An electron in a $3s$ subshell may be excited to jump into the $3p$.
Statement II : The Heisenberg uncertainty principle states that one cannot know what orbital an electron is in.

• A. Statement I is True, Statement II is True and Statement II is correct explanation of Statement I
• B. Statement I is True, Statement II is True and Statement II is not correct explanation of Statement I
• C. Statement I is True, Statement II is False
• D. Statement I is False, Statement II is True
• E. Statement I is False, Statement II is False

Answer 1

The correct option is C Statement I is True, Statement II is False

Statement I : An electron in a 3s subshell may be excited to jump into the 3p. The energy of 3p orbital is higher than the energy of 3p orbital. When an electron absorbs energy, it is excited to higher energy level.
Statement II : The Heisenberg uncertainty principle cannot state that one cannot know what orbital an electron is in.
Statement I is True, Statement II is False.
