The concept of the atom was proposed by ancient Greek philosophers Leucippus and Democritus in the 5th century BCE, suggesting that matter is composed of indivisible particles. The modern definition of an atom, as the smallest unit of a chemical element, was further developed by scientists like John Dalton, J.J. Thomson, and Ernest Rutherford in the late 19th and early 20th centuries.
An atom is the smallest unit of matter that retains the properties of an element. It consists of a nucleus containing protons and neutrons, surrounded by electrons in orbitals.
A bonded atom is an atom that is linked to another atom or atoms through the sharing or transfer of electrons, forming a chemical bond. These bonds can be covalent, where electrons are shared, or ionic, where electrons are transferred from one atom to another. Bonded atoms together form molecules or compounds.
Neutrons are neutral particles found in the nucleus of an atom. Protons are positively charged particles also found in the nucleus. Electrons are negatively charged particles that orbit the nucleus of an atom. Together, these three subatomic particles make up an atom.
The nucleus of an atom only makes up a tiny fraction of the total volume of the atom, typically less than 1%. The majority of an atom’s volume is composed of the electron cloud surrounding the nucleus.
In science, an element is a substance made up of only one type of atom. Each element is defined by the number of protons in the nucleus of its atoms, which determines its unique chemical properties. The periodic table organizes all known elements based on their atomic number and properties.

Niels Bohr
A thing which is made up of more than one type of atom. Something which is made up of just one atom is called an element.
No, a drawing of an atom is not a scientific definition. A scientific definition of an atom would describe it as the smallest unit of matter that retains the properties of an element.

A super condensed primeval atom where the laws of physics dont apply and the speed of light can be exceeded thats the idiots definition does that answer your question?
