Quantum Chemistry

Quantum chemistry deals with the properties of chemical systems and their reactions. The branch of chemistry which is more concerned with quantum chemistry is physical chemistry. It is a more sophisticated field of theoretical physics which is concerned towards the application of physical concepts towards various chemical aspects such as, formation of atoms, chemical structure descriptions, chemical bond strength, hybridization, conjugation etc. Quantum chemistry mainly studies the various states i.e., ground state, excited state, transition states of the individual atoms or molecules taking place during any chemical reaction. The laws of motion explained by various scientists, which are termed as “classical mechanics” were not acceptable in terms of electrons, protons, atoms, light etc. Thus, a new theory named “quantum mechanics” emerged to understand the basic framework of various atomic and subatomic particles.

Question

## Understanding Effective Nuclear Charge (Z*) for Valence Electrons

### Task:
Rank the effective nuclear charge $ Z^* $ experienced by a valence electron in each of these atoms:

#### Table:

| **Atom** | **$ Z^* $ experienced by a valence electron** |
|--------------------|-------------------------------------------------|
| An atom of oxygen. | (pick one) |
| An atom of carbon. | (pick one) |
| An atom of lithium.| (pick one) |
| An atom of boron. | (pick one) |

#### Explanation:

In chemistry, the effective nuclear charge $ Z^* $ is the net positive charge experienced by valence electrons. It largely influences the atom's chemical properties and trends across the periodic table. Students are required to rank these atoms based on the $ Z^* $ value for a valence electron.

**Note:** Use the dropdown selections to rank the effective nuclear charge experienced by each atom.
