Atomic Structure Vocabulary Quizs

What is an Atom?

• The smallest particle of an element that retains the chemical properties of that element, consisting of a nucleus and electrons.

• A large structure made up of multiple molecules.

• A type of chemical bond between two elements.

• A collection of similar cells that perform a specific function.

What is an Orbital?

• A two-dimensional shape representing electron paths

• A three-dimensional region around the nucleus of an atom that describes the probable location of an electron.

• A type of chemical bond between atoms

• A particle that orbits the nucleus of an atom

Isotope

• Atoms of different elements that have the same number of protons but a different number of neutrons.

• Atoms of the same element that have the same number of protons but a different number of neutrons.

• Atoms of the same element that have a different number of protons and neutrons.

• Atoms that have the same mass but different chemical properties.

What is the Atomic Number?

• The number of neutrons in an atom

• The number of protons in the nucleus of an atom

• The total number of electrons in an atom

• The mass of an atom in atomic mass units

What is an Anion?

• A positively charged ion formed when an atom loses electrons.

• A negatively charged ion formed when a neutral atom gains one or more valence electrons.

• An atom that has no charge at all.

• A type of molecule that contains both positive and negative ions.

What is the Average Atomic Mass?

• The total mass of an atom's protons and neutrons

• The weighted average mass of all naturally occurring isotopes of an element, as shown on the periodic table.

• The mass of a single isotope of an element

• The mass of an atom in grams

Element Noun

---

[el-uh-muhnt]

• A pure substance consisting of only one type of atom, which is distinguished by its unique, identifying atomic number.

• A mixture of two or more substances that can be separated by physical means.

• A compound formed by the chemical combination of two or more different elements.

• A solution that contains a solute dissolved in a solvent.

What is a Photon?

• A discrete particle of light or electromagnetic radiation emitted when an electron moves from a higher to a lower energy level.

• A type of wave that travels through a vacuum without any medium.

• A subatomic particle that carries a negative charge.

• A form of energy that can be converted into mass.

What are valence electrons?

• Electrons in the innermost energy level of an atom.

• Electrons that are involved in forming chemical bonds and located in the outermost energy level of an atom.

• Electrons that do not participate in chemical reactions.

• Electrons that are found in the nucleus of an atom.

Cation

• A negatively charged ion formed when an atom gains electrons.

• A positively charged ion formed when a neutral atom loses one or more of its valence electrons.

• An atom that has an equal number of protons and electrons.

• A neutral atom that has no charge.
