Question

Hey all, I'm having some trouble with numbers 3 & 4. I feel like I'm missing something and need some help. Thanks!!

3. Give the quantum number designations of n, l, m, of the following orbitals and list the possible m values. 40 n. 2s n, 1 5dn, mi mi 4. Draw out approximate shapes of the following atomic orbitals indicating locations of planar and radial nodes. 4 dx2-y2 3py

Answer 1

An electron in an atom can be described by four quantum numbers. Principal quantum number (W): Represents main energy level in which election is present value of n = 1, 2, 3 ... Example : I an electron is present in 4s orbital 'n? will be 4. (b) Azimuthal Quantum number w: This gives description orbital angulae momentum. value of l ranging from o to not I l = 0 1 2 3 S P d f Subshell If an election is present in 4d, then n = 4 l = 0 to 4 1 1=2 for 4d. o 1,2,3 (C) S pdf Magnetic quantum number (me): me has (21 + 1) values ranging from -l to tla Each value of in represent particular orbital. for up : n = 4 l = 0, 1, 2, 3 . S pdf. of l=1 me = -1,0, +1, means p-subshell have three orbitals. Page No.
