Atom Word Search

ATOM – The smallest unit of matter that retains the properties of an element, consisting of a nucleus surrounded by electrons in orbital shells.

ATOMIC – Relating to atoms or the energy released from splitting or combining atomic nuclei; pertaining to the fundamental building blocks of matter.

BOHR – Niels Bohr, Danish physicist who developed the Bohr model of the atom, showing electrons orbit the nucleus in specific energy levels or shells.

BOND – A chemical connection between atoms formed by sharing or transferring electrons, creating molecules and compounds through attractive forces holding atoms together.

CHARGE – An electrical property of matter that can be positive or negative, caused by an excess or deficiency of electrons in an atom or particle.

ELECTRON – A negatively charged subatomic particle that orbits the nucleus of an atom, responsible for chemical bonding and electrical conductivity in materials.

ELEMENT – A pure substance consisting of only one type of atom, characterized by its unique number of protons, and cannot be broken down chemically.

ENERGY – The capacity to do work or cause change, existing in various forms including kinetic, potential, thermal, and released during atomic reactions.

FISSION – Nuclear reaction where a heavy atomic nucleus splits into smaller fragments, releasing massive amounts of energy used in nuclear power and weapons.

FUSION – Nuclear process where light atomic nuclei combine to form heavier nuclei, releasing tremendous energy, powering stars and experimental reactors on Earth.

ION – An atom or molecule with a net electrical charge due to the loss or gain of one or more electrons during chemical reactions.

ISOTOPE – Variant forms of the same element having identical proton numbers but different neutron counts, resulting in different atomic masses and stability.

MASS – The amount of matter in an object, measured in units like grams or kilograms, representing the object’s resistance to acceleration or movement.

MATTER – Anything that has mass and occupies space, composed of atoms and molecules, existing in solid, liquid, gas, and plasma states.

MOLECULE – A group of two or more atoms bonded together chemically, representing the smallest unit of a chemical compound maintaining its properties.

NEUTRON – An electrically neutral subatomic particle found in the atomic nucleus, with mass similar to protons, determining isotopes and contributing to atomic stability.

NUCLEAR – Relating to the nucleus of an atom or the energy produced from splitting or fusing atomic nuclei in reactions and power generation.

NUCLEUS – The dense central core of an atom containing protons and neutrons, holding most of the atom’s mass and maintaining a positive charge.

ORBITAL – A region of space around an atom’s nucleus where electrons are most likely to be found, having specific shapes and energy levels.

PARTICLE – A tiny piece of matter, including subatomic particles like protons, neutrons, and electrons, or any small discrete unit of physical substance.

PROTON – A positively charged subatomic particle located in the atomic nucleus, determining the element’s identity through its atomic number and chemical properties.

QUANTUM – The smallest discrete unit of energy or matter, fundamental to quantum mechanics describing atomic and subatomic behavior at microscopic scales.

RADIATION – Energy transmitted as electromagnetic waves or moving subatomic particles, emitted from radioactive materials or nuclear reactions, potentially harmful in large doses.

SUBATOMIC – Referring to particles smaller than an atom, including protons, neutrons, electrons, and other fundamental particles comprising atomic structure and behavior.
