Some characteristics of a atom are they take on part of chemical reactions independently. Atom can be divided into sub-atomic particles and the main particles of a atom are the electron, proton and neutron.
Valence electrons are the electrons in the outermost shell of an atom.
They help to determine the reactivity of certain elements because certain numbers and configurations of valence electrons are more energetically stable than other.
Paired valence electrons are more stable than nonpaired and a valence shell with 8 electrons is most stable.
Valence electrons may reside in a number of configurations, known as orbitals. Orbitals may be designated as s, p, d, or f.
The smallest particle of any substance that maintains elemental characteristics and identity is an atom. Conversely a pure elemental sample if divided indefinitely into smaller pieces would ultimately yield the atom.
Ions carry positive or negative charges.
The atom is the smallest particle of an element that retains it's characteristics. Sub-atomic particles such as protons, neutrons and electrons form the atom and it is the amount of each of these sub-atomic particles that make the element that element.

A radioactive atom is an atom of an element with an unstable nucleus.
The smallest particle that has characteristics of that element is the atom. The atom is made up of a certain amount of protons, electrons and (neutrons) and those are what give the characteristics of that element to that atom.
That would be an atom. Atoms go down to protons, neutrons and electrons, but these do not have unique characteristics. So, the smallest particle with unique characteristics is an atom.
The number if electrons in an atom is limited.
I'm Doing chemistry I'm my class and the textbook says its made of protons and neutrons.

This particle is the atom.
These are the electrons.
An atom of that element has all the properties of that element.
