This Russian scientist is considered to be the father of the periodic table.

Who is Mendeleev?

100

Where neutrons and protons are located in an atom

What is the nucleus?

100

The outermost occupied energy shell of an atom

What is the valence shell?

100

The type of compound made up of a cation and an anion

What is an ionic compound?

200

These are made up of one type of atom and cannot be broken down into simpler substances

What is an element?

200

A vertical column of elements in the periodic table

What is a group?

200

The modern periodic table is organized based on this property of each element.

What is atomic number? Or, what is number of protons?

200

The element found in group 17, row 3.

What is chlorine?

200

The charge of an iron (III) ion

What is 3+?

300

These are pure substances that consist of two or more elements and can be broken down chemically, but not physically

What are compounds?

300

The most stable (non-reactive) group of elements on the periodic table

What are the noble gases?

300

What a neutral atom becomes when it gains or loses electron(s)

What is an ion?

300

The number of electrons in a sodium atom

What is 11?

300

The chemical formula of dioxygen pentafluoride.

What is O2F5?

400

The type of reaction in which energy is released from the system.

What is an exothermic reaction?

400

Group 2 metals

What are the alkaline-earth metals?

400

Atoms in the same group have the same number of these.

What are valence electrons?

400

These type of elements become more reactive as you move down the periodic table

What are metals?

400

The chemical formula of magnesium nitrate.

What is MgNO3?
500

Colour, malleability, texture, boiling point, melting point, hardness, and solubility are all examples of this type of property.

What are physical properties?

500

Elements that are shiny and solid at room temperature, but also brittle and poor conductors of heat and electricity.

What are semi-metals?

500

A magnesium ion has the same electron arrangement as this element

What is neon?

500

The reason why atomic size decreases moving left to right across a period

What is the number of valence electrons increase but the number of valence shells stays the same. More protons in the nucleus results in a stronger positive charge that pulls the electrons closer to the nucleus.
