Question

Part B Identify the sets of quantum numbers that describe all the electrons in the ground state of a neutral beryllium atom, Be. Each set is ordered (n,l,ml, m8). Drag the appropriate items to their respective bins. Quantum Numbers Every electron in an atom is described by a unique set of four quantum numbers: n, l, ml, and m8. The principal quantum number, n, identifies the shell in which the electron is found. The angular momentum quantum number, l, indicates the kind of subshell. The magnetic quantum number, ml, distinguishes the orbitals within a subshell. The spin quantum number, m, specifies the electron spin. Part A Identify which sets of quantum numbers are valid for an electron. Each set is ordered (n, l, ml, m8,). Check all that apply.

Explanation / Answer

Part A. Following set of quantum numbers are valid -

2,1,1,1/2

3,2,-1,-1/2

4,3,2,1/2

3,2,0,1/2

3,0,0,1/2

Quantum numbers that describe all the electrons in the ground state of a neutral beryllium atom -

1,0,0,1/2

1,0,0,-1/2

2,0,0,1/2

2,0,0,-1/2
