Question

Molecules of a single element

Answer 1

Answer:

A molecule is the smallest particle of a substance that exists independently. Molecules of most elements are made up of only one of atom of that element. Oxygen, along with nitrogen, hydrogen, and chlorine are made up of two atoms

different chemical elements. Examples of diatomic molecules are O2 and CO.

Heteronuclear Diatomic Molecules -- A heteronuclear diatomic molecule consists of two of atoms of the same element combined. There are seven diatomiceElements: Hydrogen (H2), Nitrogen (N2), Oxygen ( O2), Fluorine ( (F2), Chlorine ( (Cl2), --Iodine ( (I2) and Bromine (Br2) . These seven elements are so reactive that they can be found very often bonded with another atom of the same type.

OXYGEN MOLECULE

Homonuclear diatomic molecules --A homonuclear diatomic molecule consists of two atoms of different elements chemically combined. Examples of homonuclear diatomic molecules are: carbon monoxide, hydrocholoric acid (HCl) , and Hydrogen Flouride (HF)

carbon monoxide molecule CARBON MONOXIDE MOLECULE (CO)

WHAT IS THE DIFFERENCE BETWEEN A MOLECULE AND A COMPOUND?

While all compounds are molecules, not all molecules are compounds.

A molecule is formed when two or more atoms of an element chemically join together. If the types of atoms are different from each other, a compound is formed. Not all molecules are compounds, since some molecules, such as oxygen gas (above image of molecule of-O2) or ozone (O3), consist only of one element or type of atom.

Water is also a molecule because it is made from atoms that have been chemically combined. But water is also a compound since the atoms that make water are not all the same. Water (H2O) is made from one oxygen atom (shown in red below) and two hydrogen atoms (shown in white below).

About the Water Molecule

Water is a simple molecule made of one oxygen and two hydrogen atoms covalently bound. Water is also considerd a compound. While the forces that hold the hydrogen and oxyen together are strong forces, water molecules are bound by hydrogen bonds which are bonds between a hydrogen in one polar water molecule and the negatviely charged end of another water molecule. The forces in liquid water are temporary as shown below in the Molecular Dynamics Simulation of water molecules at room temperature. The green dashed lines show the hydrogen bonds which are constantly being broken and reformed over time.
