Elements found in small amounts in living things are called trace elements. Among the trace elements that have vital functions in humans and plants are boron, chromium, selenium, and molybdenum. Of course, the natural element present in the smallest amount (not at all), which is not necessary, is francium.
The smallest unit of an element that is still that element is an atom. Some elements normally exist as molecules, but under some circumstances these can be broken down to individual atoms.
An atom is the smallest building block of matter that retains the characteristics of that matter.
The smallest particle of an element that can exist and still retain the properties of the element is an atom. Atoms are composed of a nucleus containing protons and neutrons, surrounded by electrons. The number of protons in the nucleus determines the element's identity.
Quarks are the smallest parts of an element that have been discovered so far.
The smallest part of any chemical element that can exist is an atom of that element. The smallest part of a chemical compound that can exist is a molecule of that compound.
The smallest amount of an element is called an atom. Atoms are the basic building blocks of matter and consist of a nucleus containing protons and neutrons, surrounded by electrons. Elements are made up of one kind of atom.
The smallest particle of matter is called an atom. It is the basic unit of a chemical element and retains the properties of that element.
The smallest unit of Matter that retains the property of an element is the atom.

An atom is a unit of matter that has all the properties of an element. It is the smallest unit of an element that retains the chemical properties of that element.
