What is a building block of matter?

Answer 1

The traditional answer is "atoms". But it really depends on what you mean by a "building block". Atoms are made of protons, neutrons and electrons which are themselves made of more fundamental particles. Atoms combine into molecules. So it depends where you want to draw the line.

Answer 2

Because an atom has characteristics that make it different from other atoms. For example, a carbon atom is uniquely different than, say an oxygen atom. But elections, neutrons, and protons don't define the properties of the substance. The atoms do, though. You might argue that molecules (arrangements of atoms) are basic building blocks, but you'd be wrong because that eliminates substances made of atoms (not having molecular structures), such as aluminum, iron, hydrogen, sulfur, etc. So atoms are the basic building blocks of matter.

Answer 3

atoms
matter exists as solids liquids and gases
all have atoms as their building blocks

an atom cannnot be divided into smaller particle
it can join with others to make molecules

Answer 4

Standard Model: Quarks and electrons

String Theory: Strings of vibrating energy
