Periodic Table Test

Front

What is the periodic table?

Back

A tabular arrangement of chemical elements, organized by increasing atomic number, electron configuration, and recurring chemical properties.

Front

What are metals?

Back

Elements that are typically shiny, good conductors of heat and electricity, malleable, and ductile.

Front

What are nonmetals?

Back

Elements that are generally poor conductors of heat and electricity, and are not malleable or ductile.

Front

What are metalloids?

Back

Elements that have properties of both metals and nonmetals, often found along the zigzag line on the periodic table.

Front

What are halogens?

Back

A group of nonmetals in Group 17 of the periodic table, known for their reactivity and tendency to form salts.

Front

What are protons?

Back

Positively charged particles located in the nucleus of an atom.

Front

What are neutrons?

Back

Neutral particles located in the nucleus of an atom, contributing to the atomic mass.

Front

What are electrons?

Back

Negatively charged particles that orbit the nucleus of an atom.

Front

What is atomic number?

Back

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

Front

What is atomic mass?

Back

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