Question: What Are Some Examples of Atoms?
Atoms are fundamental units of matter that cannot be broken down using any chemical means. Here are some examples of atoms.
Many atoms consist of a positively-charged nucleus of protons and neutrons surrounded by a negatively-charged cloud of electrons. At its most basic level, an atom is any matter that contains at least a proton. Atoms may be neutral or electrically charged. A single particle of any element listed in the periodic table
is an atom. Here are some examples of atoms:
- neon, Ne
- hydrogen, H
- plutonium, Pu
- protium, an isotope of hydrogen
- a calcium ion, Ca2+
