Periodic Table - History and Format Revision

The Periodic Table is organised into rows and columns called:

• Periods and Families

• Metals and Non-metals

• Periods and Groups

• Groups and Families

The elements are organised by:

• increasing atomic mass

• increasing atomic number

• alphabetical order

• number of neutrons

John Dalton created a periodic table of elements. He organised them based on:

• number of electrons

• number of protons

• atomic mass

• year of discovery

Mendeleev's Periodic Law states:

• the properties of an element are a function of their atomic mass

• the properties of an element are a function of their atomic number

• groups have similar properties

• elements have repeating properties

Metals are found on the right side of the periodic table.

• True

• False

K is the chemical symbol for

• Krypton

• Potassium

• Kentuckium

• Kalcium

Non-metals are found on the right side of the Periodic Table.

• True

• False

Henry Moseley developed the modern Periodic Table. He organised elements based on their:

• atomic masses

• number of neutrons

• atomic number

• relative abundance

Metals have many properties. Which of the following is NOT a property of a metal?

• Ductile

• Malleable

• Gains electrons when bonding

• Conducts heat and electricity

You are investigating a substance which is brittle, and a poor conductor. This substance is likely to be a:

• Metalloid

• Metal

• Non-metal
