What element made of molecules with two atoms?

Answer 1

A molecule made of two identical atoms is called diatomic.

Five diatomic elements exist as gases at room temperature (25oC/298K) and atmospheric pressure:

• Hydrogen, H2
• Nitrogen, N2
• Oxygen, O2
• Fluorine, F2
• Chlorine, Cl2

One diatomic element is a liquid at room temperature and atmospheric pressure:

• Bromine, Br2

One diatomic element is a solid at room temperature and atmospheric pressure:

• Iodine, I2

Answer 2

There are seven elements that are diatomic molecules. The majority of them are gases, two are not. The easiest way to remember the seven elements that come as diatomic molecules is: HOFBrINCl. The five that are gases are: Hydrogen, Oxygen, Fluorine, Nitrogen and Chlorine. (Bromine is a liquid and Iodine is a solid at room temp.)

Answer 3

Elements are not made of molecules. Molecules are made of elements.

There are a number of elements which form molecules consisting of two atoms. Oxygen, nitrogen, hydrogen, chlorine, etc., all form gases composed of diatomic molecules.

Answer 4

Air consists of two main ingredients, nitrogen and oxygen, and both of those form molecules with two atoms (formally known as diatomic molecules). Carbon dioxide has three atoms per molecule.

Answer 5

Oxygen (O2) is an element composed of molecules with two atoms. These oxygen molecules are diatomic, meaning they exist as pairs of atoms bonded together.

Answer 6

Carbon Dioxide ( 1 Carbon 2 Oxygen)
