Why should a student nurse study chemistry?

here are the answers to your next set of questions:

1. Why should a student nurse study chemistry?
A student nurse should study chemistry to understand the fundamental chemical processes occurring in the human body, such as metabolism and respiration. This knowledge is crucial for comprehending how medications work, interpreting diagnostic tests, understanding fluid and electrolyte balance, and ensuring safe and effective patient care.

2. What are atoms?
Atoms are the basic building blocks of all matter. They are the smallest unit of an element that retains the chemical identity of that element. Atoms consist of a central nucleus containing protons and neutrons, surrounded by electrons orbiting the nucleus.

3. Which of the following elements exist as diatomic molecules?
The elements that exist as diatomic molecules are those that naturally occur as two atoms bonded together (e.g., $\text{H}_2, \text{N}_2, \text{O}_2, \text{F}_2, \text{Cl}_2, \text{Br}_2, \text{I}_2$).
From the given options:

• a. helium (He) - Noble gas, exists as a single atom.
• b. hydrogen ($\text{H}_2$) - Exists as a diatomic molecule.
• c. iodine ($\text{I}_2$) - Exists as a diatomic molecule.
• d. gold (Au) - Metal, exists as individual atoms.

Therefore, the correct options are:

• b. hydrogen
• c. iodine

4. Which of the following elements exist as diatomic molecules?
From the given options:

• a. chlorine ($\text{Cl}_2$) - Exists as a diatomic molecule.
• b. potassium (K) - Metal, exists as individual atoms.

Therefore, the correct option is:

• a. chlorine
