Define an atom and describe the function of protons, neutrons, and electrons within it.
Understand the Problem
The question asks for a definition of an atom and a description of the roles of its constituent particles: protons, neutrons, and electrons. This requires providing a basic understanding of atomic structure and the function of each subatomic particle within the atom.
Answer
An atom comprises protons, neutrons, and electrons. Protons and neutrons form the nucleus, while electrons orbit the nucleus. Protons determine the element, neutrons affect stability, and electrons dictate chemical behavior.
An atom is the basic building block of matter, consisting of protons, neutrons, and electrons. Protons (positive charge) and neutrons (neutral charge) form the nucleus, while electrons (negative charge) orbit the nucleus. Protons determine the element, neutrons contribute to the atom's mass and stability and electrons dictate chemical behavior.

More Information
Atoms are the smallest unit of matter that retains an element's chemical properties. Atoms can combine to form molecules.
Tips
It's easy to confuse the charges of protons and electrons. Remember, protons are positive, and electrons are negative.
