हिन्दीConsider the following statements about quantum rules and orbitals:\n(A) The principal quantum number \( n \) defines the main shell and size of the orbital.\n(B) For a given value of \( n \), there are \( n \) allowed values of \( l \).\n(C) The number of \( m_l \) values for a given \( l \) is \( 2l + 1 \).\n(D) The total number of electrons in a given subshell is \( 2l + 1 \). \nWhich of the above statements are correct?
Correct answer · Option 2
(A), (B) and (C) only
Explanation
Statements (A), (B), and (C) are correct. Statement (D) is incorrect because total electrons in a subshell is \( 2(2l+1) \), not \( 2l+1 \).
