The smallest particle of an element that cannot be broken down any further. Positive Atom Solid

## Step 1<br />The problem is asking for the smallest particle of an element that cannot be broken down any further. This is a fundamental concept in chemistry, specifically in the study of atomic structure.<br /><br />## Step 2<br />The smallest particle of an element that cannot be broken down any further is known as an atom. Atoms are the basic building blocks of matter and are the smallest unit of an element that retains the properties of that element.<br /><br />## Step 3<br />Atoms are composed of three types of subatomic particles: protons, neutrons, and electrons. Protons and neutrons are located in the nucleus of the atom, while electrons orbit the nucleus.<br /><br />## Step 4<br />Atoms are not just solid; they are composed of a nucleus (which is solid) and electrons (which are not solid). The electrons are in constant motion around the nucleus, why atoms are not considered solid.<br /><br />## Step 5<br />Atoms are not positive; they are neutral. This is because they contain an equal number of protons (which carry a positive charge) and electrons (which carry a negative charge). The positive and negative charges cancel each other out, resulting in a neutral atom.
