Alenkasestr [34]

The chemical properties of an atom are determined by the number of the electrons while bonding is determined by the arrangement and the valency of the electrons.

<h3>What is an Atom?</h3>

The smallest component of ordinary stuff that makes up a chemical element is an atom.  Atoms that are neutral or ionized make up every solid, liquid, gas, and form of plasma. Atoms are incredibly tiny, measuring typically 100 picometers across. Due to quantum effects, they are so small that it is impossible to predict their behavior with sufficient accuracy using classical physics, as would be the case, for example, if they were tennis balls.

Each atom is made up of a nucleus and one or more electrons that are linked to it. One or more protons and a significant number of neutrons make up the nucleus. Only the most prevalent type of hydrogen is neutron-free. The nucleus of an atom contains more than 99.94% of its mass.
