Front

What is an element with the number of protons equal to the number of electrons called?

Back

Neutral Elements are elements that have no overall charge because the number of protons equals the number of electrons.

Front

What are the simplest molecular compounds that consist of two atoms, such as oxygen (O2) and nitrogen (N2)?

Back

Diatomic Molecules are molecules that contain two atoms, which can be of the same or different elements.

Front

What is the name of the table that organizes all known chemical elements?

Back

The Periodic Table is a tabular arrangement of the chemical elements, organized by their atomic number, electron configuration, and recurring chemical properties.

Front

What do you call a solution that contains more solute than it can normally dissolve?

Back

A Supersaturated Solution is a solution that has more dissolved solute than it can normally hold at a given temperature.

Front

What is the term for one or two letters that represent an element?

Back

A Chemical Symbol is a notation of one or two letters representing a chemical element.

Front

What is the term for a charged particle that has either lost or gained electrons?

Back

An Ion is a charged particle that results from the loss or gain of electrons.

Front

What is the term for a molecule that consists of three or more atoms?

Back

A Polyatomic Molecule is a molecule that contains three or more atoms.

Front

What is the term for a solution that contains less solute than it can dissolve?

Back

An Unsaturated Solution is a solution that can still dissolve more solute at a given temperature.

Front

What is the term for the number of protons in the nucleus of an atom?

Back

The Atomic Number is the number of protons in the nucleus of an atom, which determines the element's identity.

Front

What is the term for the average mass of an element's isotopes?

Back

The Atomic Mass is the weighted average mass of an element's isotopes, measured in atomic mass units (amu).
