I'd venture to say the electrons themselves. They're so small they don't even exist in a concrete place, they are just in a cloud of places they could be. The nucleus is amazingly small compared to the size of the whole atom, but it still has weight, mostly unlike the electron.
The smallest possible particle of gold that can exist is called a gold atom. Gold atoms are the basic units that make up gold and can exist on their own or be part of larger structures.
The atom is the smallest known particle.
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.
A molecule is the smallest particle of a "compound" being that compounds are made up of more than one atom. The smallest particle of any "chemical element" that retains its properties would be the atom.
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.
An atom is the smallest particle that is still recognisably the element
No, an atom is
The smallest possible particle of gold that can exist is called a gold atom. Gold atoms are the basic units that make up gold and can exist on their own or be part of larger structures.
a subatomic particle
The atom is the smallest known particle.
That's an atom of gold. An atom is the smallest representative particle of an element.
A molecule is the smallest part of a compound that still retains the properties of said compound. As the atom is the smallest particle of an element into which it can be divided and still retain all the properties of that element, the molecule is the atom's analog for a compound.
The smallest possible part of a material such as copper is an atom. Copper atoms are the building blocks of the copper material.
The smallest part of an atom would be a quark. Quarks are either up or down quarks, and have virtually no mass. Neutrinos have even less mass, but are not part of an atom.
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.
A molecule is the smallest particle of a "compound" being that compounds are made up of more than one atom. The smallest particle of any "chemical element" that retains its properties would be the atom.
The electron is actually the smallest particle. The neutron is the largest particle, followed closely by the proton. The electron is much, much smaller.
