Question

A molecule of oxygen consists of how many atoms of oxygen?

A.

Eight

B.

Six

C.

Four

D.

Two

Correct option is D

The correct answer is (D) Two.

A molecule of oxygen (O₂) consists of two oxygen atoms. Oxygen is a diatomic molecule, which means that it naturally exists as two atoms bonded together. This is true for several gases, including hydrogen (H₂), nitrogen (N₂), and others.

The two oxygen atoms in an O₂ molecule are held together by a double bond, which means that they share two pairs of electrons. This double bond makes the oxygen molecule stable under normal conditions.

The O₂ molecule is essential for respiration in most living organisms, and it also plays a critical role in combustion reactions.

Information Booster:

● Oxygen in its molecular form (O₂) is essential for respiration in animals and many other organisms.
● Oxygen is the most abundant element in the Earth's crust, and it also makes up about 21% of the Earth's atmosphere.
● While oxygen exists as O₂, ozone (O₃) is another form, where three oxygen atoms are bonded together. Ozone plays a critical role in protecting the Earth from ultraviolet radiation.
● Oxygen is highly reactive and can form compounds with almost all other elements.
● Oxygen was first discovered by Carl Wilhelm Scheele and Joseph Priestley independently in the 1770s.
