What is the smallest thing in the universe?

As far as we can tell, quarks can’t be broken down into smaller components, making them the smallest things we know of.

Is nanometer The smallest unit?

A nanometer (nm) is 1,000 times smaller than a micrometer. It is equal to 1/1,000,000,000th or one-billionth of a meter. … Atoms are smaller than a nanometer. One atom measures ~0.1-0.3 nm, depending on the element.

What is the smallest particle of an element?

atomsAn atom is the smallest particle of an element, having the same chemical properties as the bulk element. The first accurate theory explaining the nature of matter was Dalton’s Atomic Theory: 1. All matter is composed of atoms, and atoms are indivisible and indestructible.

What is the basic unit of matter?

Different elements are different kinds of matter distinguished by different physical and chemical properties. In turn, the atom is the fundamental unit of matter…, that is, of an element. The number of positively charged protons and neutral neutrons in an atomic nucleus account for most of the mass of an atom.
