Some natural chemical elements are stable, some are not stable; all the artificial elmemets are unstable. Also be sure that several natural elements have stable and unstable isotopes.
Atoms are neutral on the Periodic Table. Ions consist of more or less electrons than atoms.
All the atoms are neutral. Only ions have an electrical charge.
An atom of an element for example Neon (Ne) is neutral (no positive or negative charge as it has 8 electrons in the outer shell) and is very stable. It is a noble gas because the outer electron shell is filled which makes it largely chemically inert, and it is stable because it's usual isotope does not undergo nuclear decay. Most of the 92 naturally occurring elements, in their most abundant isotope, are stable.
Group 18, starting with Helium
All stable Atoms have the same neutral charge, and cannot be divided into smaller units while retaining their chemical identity

For the atom to be neutral, the positive and negative charges must cancel each other out.
In the Periodic Table of elements you have elements, these elements represent neutral atoms of elements, ions are just like neutral atoms, the only difference is the have less or more electrons in the orbital. So Na is sodium atom and Na+ is sodium ion
Unless it is an element that has a full valence shell naturally - like neon, krypton, etc. - atoms are incredibly unstable. When a compound is formed the atoms either share or exchange electrons in order to completely fill their valence shells.

A neutral atom of silicon will have 4 valence electrons. The amount of valence electrons that a neutral atom will have can be found by the atoms group number in the periodic table.
Zinc has 5 stable isotopes (64, 66, 67, 68, and 70), all of which are neutral atoms at standard temperature and pressure. Zinc has many more isotopes that are radioactive, but these too are usually neutral atoms.
