What is the electron configuration of the second excited state of lithium?

Short Answer

Expert verified

The electronic configuration of second excited state for lithium atom is1s23s1

Step by step solution

01

Step 1. Given information

The number of possible electrons in sorbital (or shell) is 2 ,

the number of possible electrons in porbital (or shell) is 6 ,

the number of possible electrons in orbital (or shell) is 10,

and the number of possible electrons in gorbital (or shell) is 14 .

02

Step 2. Explanation

We must determine the electron configuration of lithium's second exited state.

In the ground state, the lithium atom (Z= 3) contains two electrons in the 1s shell and one electron in the 2s shell.

For the first excited state of lithium, the electron configuration is:

1s22p

As a result, the electron configuration for lithium's second excited state is:

1s23s

Three electrons are in a one-dimensional rigid box (i.e., an infinite potential well) of length 0.50nm. Two are in the n = 1 state and one is in the n = 6 state. The selection rule for the rigid box allows only those transitions for which n is odd.

a. Draw an energy-level diagram. On it, show the filled levels and show all transitions that could emit a photon.

b. What are all the possible wavelengths that could be emitted by this system?

In a multielectron atom, the lowest-lstate for eachn2s,3s,4s,etc.is significantly lower in energy than the hydrogen state having the same n. But the highest-l state for each n(2p,3d,4fetc) is very nearly equal in energy to the hydrogen state with the same n. Explain.

Consider the three hydrogen-atom states 6p,5d and 4f. Which has the highest energy?

Show that hc=1240eVnm.
