Homework Answers
Q1) All these belong to 2nd period and Ne has the highest as it
has octet(completed shell) of electrons.
So the order is
Ne > N > O > Be > B
N and Be have more than their following elements (not following the
trend) due the stable half filled (2p3 for N )and filled (2s2 )for
Be.
OPTION 4
Q2)
OPTON 2
In ground state the electrons follow Aufbau, Hund's and Pauli principle and second one follows all these.
First one violates Pauli rule
3rd one violates aufbau rule
fourth one is in excited state
fifth one violates Hund's rule.
Q3)
All the orbitals in a given shell of an atom have same (n) principal quantum number .
Like in 3rd shell 3s, 3p and 3d.

Quantum Number Rules Learning Goal: To learn the restrictions on each quantum number. Quantum numbers can be thought of as labels for an electron. Every electron in an atom has a unique set of four quantum numbers. The principal quantum number n corresponds to the shell in which the electron is located. Thus n can therefore be any integer. For example, an...

Which of the following statements is TRUE? The angular momentum quantum number (1) describes the orientation of the orbital. The magnetic quantum number (mi) describes the size and energy associated with an orbital. The principal quantum number (n) describes the shape of an orbital. O An orbital is the path that an electron follows during its movement in an atom. The spin quantum number (ms) describes the orientation of the spin of the electron.

No Brief illustration 90.3 Spin-orbit coupiny The unpaired electron in the ground state of an alkali metal atom has l=0, so j=1. Because the orbital angular momen- tum is zero in this state, the spin-orbit coupling energy is zero (as is confirmed by settingj=s and 1=0 in eqn 9C.4). When the electron is excited to an orbital with I=1, it has orbital angular...
