The small, positively charged center of an atom, contains protons and neutrons

A positively charged subatomic particle, located in the nucleus and with an electric charge of 1+

A subatomic particle inside the nucleus with a neutral charge

A subatomic particle with a negative electric charge, that surrounds the nucleus

Particle of matter that makes up protons and neutrons

The particles that make up a atom: protons, neutrons, and electrons

This term describes the fuzzy, cloud-like area where electrons exist and move within an atom, rather than following specific paths.

It's the space around an atomic nucleus where electrons move, forming a kind of "cloud" due to their rapid and unpredictable motion.

A atom of an element that has a specific number of neutrons

A table of the chemical elements arranged in order of increasing atomic number and in changes in chemical and physical properties

A horizontal row that organizes elements based on the number of energy levels (shells) in their atoms

A vertical column that organizes elements with similar properties and the same number of electrons in their outermost energy level

A pure substance consisting of only one type of atom, characterized by a unique atomic number and chemical properties
