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 covalent bond that forms a stable H$$_2$$ molecule.

Question 2

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

Accepted Answer

$$\mathrm{H^+H^-}$$

Question 3

What is the main driving force for the formation of the H$$_2$$ molecule from two hydrogen atoms, as depicted in the image?

Accepted Answer

The need for each hydrogen atom to achieve a noble gas electron configuration by sharing electrons.

Question 4

According to the image, what type of orbitals overlap to form the covalent bond in H$$_2$$?

Accepted Answer

Two 1s orbitals

Question 5

Which of the following best explains why the H$$_2$$ molecule is more stable than two separate hydrogen atoms?

Accepted Answer

The shared electron pair allows each hydrogen atom to achieve the electron configuration of helium.
