What is an element?

Back

An element is a pure substance that cannot be broken down into simpler substances by chemical means, consisting of atoms with the same number of protons.

Front

What is the atomic number of an element?

Back

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

Front

What is a compound?

What is the significance of the groups in the Periodic Table?

Back

Groups (columns) in the Periodic Table contain elements with similar chemical properties and the same number of valence electrons.

Front

What is the significance of the periods in the Periodic Table?

Back

Periods (rows) in the Periodic Table indicate the number of electron shells in the atoms of the elements.

Front

What is a metal?

Back

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

Front

What is a non-metal?

Back

Non-metals are elements that are generally poor conductors of heat and electricity and can be gases, liquids, or brittle solids.

Front

What is a metalloid?

Back

Metalloids are elements that have properties of both metals and non-metals, often used in semiconductors.

What is the role of noble gases in the Periodic Table?

Back

Noble gases are elements in Group 18 that are inert and do not readily react with other elements due to their full valence electron shell.
