This Russian Chemist and teacher developed a way to classify elements into what is now known as the periodic table.

Who is Dimitri MendeleeV?

100

This is anything with mass and takes up space.

What is matter?

100

The amount of matter in an object.

What is mass?

100

These elements found in Group 17 of the periodic table can form salt when reacting with metals.

What are halogens?

100

The ability of matter to carry along, an electric current.

What is conductivity?

200

Elements were originally organized by this atomic property, in which the amount of matter in an object is measured. 

What is atomic mass?

200

This particular matter can vary in composition.

What is a mixture?

200

The amount of space something takes up.

What is volume?

200

This group 14 non-metal is the only one of its kind. It is solid and found in most of the compounds that make up living things.

What is carbon?

200

The ability of a metal to reflect light.

What is luster?

300

This term related to the periodic table means, "repeating pattern"

What is periodic?

300

This is a substance that has one type of atom.

What is an element?

300

This is known as mass per unit volume of a substance.

What is density?

300

These group 18 elements, are non reactive, and are only reactive under special conditions within a laboratory.

What are noble gases?

300

This property is when a substance conducts electricity at high temperatures, but not at low temperatures.

What is a semiconductor?

400

In the early 1900's Henry Moseley reorganized the periodic table using this number.

What is the atomic number?

400

Matter with a composition that is always the same.

What is a substance?

400

A change in size shape, form or state of matter in which the identity stays the same.

What is a physical change?

400

Silicon is an element found in this group. These elements have physical and chemical properties of both metal and non-metals.

What are metalloids?

400

The ability of a substance to be hammered or rolled into sheets.

What is malleability?

500

After ordering the periodic table by atomic number it was found that elements with the same properties are found to be located in the same column or this.

What is a group?

500

This is a type of substance containing atoms of two or more different elements chemically bonded together.

What is a compound?

500

Chemical changes used to form new substances can be shown using this.

What is a chemical equation?

500

These elements have no metallic properties.

What are non-metals?

500

The ability to be pulled into thin wires.

What is ductility?
