nswer each of the following questions. Be thorough in your answers, and provide complete support.

Write the ground-state electron configuration for oxygen.

Draw the orbital diagram for the ground state of oxygen. Justify your placement of electrons in the diagram.

Write an electron configuration for oxygen in an excited state. Explain your answer. and show how the orbital diagram would be modified from the one in part b.

When oxygen returns from an excited state to its ground state, explain why we do not see white light.

Interpretation Introduction

(a)

Interpretation:

The ground state electron configuration of oxygen is to be stated.

Concept Introduction:

The distribution of the electrons that exists in the atomic orbital of an atom is collectively known as electron configuration. The description of every electron in an orbital is given by the electron configuration of that atom.

Explanation

Oxygen has an atomic number of 8. The electron configuration of oxygen is 1s22s

Interpretation Introduction

(b)

Interpretation:

The orbital diagram of oxygen is to be drawn.

Concept Introduction:

The distribution of the electrons that exists in the atomic orbital of an atom is collectively known as electron configuration. The description of every electron in an orbital is given by the electron configuration of that atom.

The electrons can also be shown in the form of boxes where the boxes represent the subshells and they are placed one over the other in increasing energy. This diagram is known as orbital diagram.

Interpretation Introduction

(c)

Interpretation:

The excited state electron configuration of oxygen is to be stated and an explanation corresponding to the same is to be given. The modified orbital diagram is to be shown.

Concept Introduction:

The distribution of the electrons that exists in the atomic orbital of an atom is collectively known as electron configuration. The description of every electron in an orbital is given by the electron configuration of that atom.

The electrons that are present in the outermost shell of an atom are known as valence electrons. The outermost shell of an atom is known as valence shell. The valence electrons are more loosely held than the electrons which are closer to the nucleus.

Interpretation Introduction

(d)

Interpretation:

The reason as to why white light is not observed when oxygen returns from excited state to ground state is to be stated.

Concept Introduction:

Electrons get excited from their ground state level to high state level on absorbing energy. When they returning back to their original state, they radiate energy and if this energy falls in visible region, color will be observed.
