Atoms and the Periodic Table

Front

What are metals?

Back

Metals are elements that are typically found on the left side of the zig-zag line on the periodic table. They are good conductors of heat and electricity, have a shiny appearance, and are malleable and ductile.

What is an atom?

Back

An atom is the smallest unit of a chemical element, consisting of a nucleus surrounded by electrons. Each chemical element is made up of only one kind of atom.

What does the Atomic Number indicate?

Back

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

What is the significance of the atomic number in the periodic table?

Back

The atomic number tells us the number of protons in an element, which is crucial for understanding its chemical properties and its position in the periodic table.

Front

What are metalloids?

Back

Metalloids are elements that have properties of both metals and non-metals. They are found along the zig-zag line on the periodic table.

Front

What is a non-metal?

Back

Non-metals are elements that are typically found on the right side of the zig-zag line on the periodic table. They are poor conductors of heat and electricity and are often brittle.

Front

What is a chemical element?

Back

A chemical element is a pure substance that cannot be broken down into simpler substances by chemical means. Each element is defined by its number of protons.

Front

What is a molecule?

Back

A molecule is a group of two or more atoms bonded together. Molecules can consist of the same or different types of atoms.

What are neutrons?

Back

Neutrons are subatomic particles found in the nucleus of an atom. They have no charge and contribute to the atomic mass of an element.

Front

What are isotopes?

Back

Isotopes are variants of a chemical element that have the same number of protons but different numbers of neutrons, resulting in different atomic masses.
