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.
Answer: 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
