Question 1

The image above illustrates the formation of a covalent bond between two hydrogen atoms. Which of the following statements best describes what is happening in this process?

Accepted Answer

The two hydrogen atoms share a pair of electrons, resulting in a stable molecule with a helium-like electron configuration.

Question 2

Which of the following best represents the electron configuration of each hydrogen atom in the H$$_2$$ molecule after bond formation?

Accepted Answer

Each hydrogen atom has two electrons in its 1s orbital, achieving the configuration of helium.

Question 3

What is the significance of the shared electron pair shown in the hydrogen molecule (H$$_2) in $$the image?

Accepted Answer

It creates a region of negative charge that holds the two nuclei together through electrostatic attraction.

Question 4

Which of the following is NOT a correct way to represent the hydrogen molecule as shown in the image?

Accepted Answer

$$\mathrm{H=H}$$

Question 5

Based on the image, what type of orbitals are overlapping to form the covalent bond in H$$_2$$?

Accepted Answer

Two 1s orbitals
