Atoms and Periodic Table Review

Front

What are non-metals?

Back

Non-metals are elements located on the right side of the zig-zag 'staircase' on the Periodic Table (except for Hydrogen). They typically have properties opposite to metals, such as being poor conductors of heat and electricity.

What are metals?

Back

Metals are elements located on the left side of the zig-zag 'staircase' on the Periodic Table (except for Hydrogen). They are usually good conductors of heat and electricity and are malleable and ductile.

What is the atomic mass of Fluorine (F)?

Back

The atomic mass of Fluorine (F) is 19.

Front

What is the atomic number of an element with three protons?

Back

The atomic number of an element with three protons is 3.

Front

What does ductile mean?

Back

Ductile refers to a material's ability to be drawn into a wire. Ductile materials can be stretched without breaking.

Front

What are metalloids?

Back

Metalloids are elements that have properties of both metals and non-metals. They are located along the zig-zag 'staircase' on the Periodic Table.

Front

What is the Periodic Table?

Back

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

Front

What is an element?

Back

An 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 atomic number?

Back

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

Front

What is atomic mass?

Back

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