Why is it called diatomic?

Diatomic molecules are molecules composed of only two atoms, of the same or different chemical elements. The prefix di- is of Greek origin, meaning “two”. If a diatomic molecule consists of two atoms of the same element, such as hydrogen (H2) or oxygen (O2), then it is said to be homonuclear.

Which gas is not diatomic at STP?

Only H, N, O, F and Cl are diatomic elemental gases under STP. Br and I are diatomic liquid and solid respectively, under STP. Oxygen remains diatomic in liquid state, while nitrogen and all halogens(F, Cl, Br, I) are diatomic in all three classical physical states.

What are the 2 polyatomic elements?

definition. …than two atoms are termed polyatomic molecules, e.g., carbon dioxide (CO2) and water (H2O). Polymer molecules may contain many thousands of component atoms.

Why is methane bad?

When methane is produced from non-fossil sources such as food and green waste , it can literally take carbon out of the air. However, methane that is released into the atmosphere before it is burned is harmful to the environment. Because it is able to trap heat in the atmosphere, methane contributes to climate change.
