SNC2D - Chapter Five

Periodic Table

100

This element is a halogen in the second period

What is Lithium

200

This element is the unreactive gas of the second period

What is Neon

300

Going down the groups of the periodic table, this trend is evident

What is increased reactivity 

OR

What is increase number of orbitals

400

This chemical family on the periodic table is the most reactive of them all.  Identify the family and explain why they are the most reactive

Alkali Metals, because they only have one valence electron

500

In the land of imagination there is an element that has an atomic number 135.  Which chemical family is this element apart of and how many valence electrons does it have?

Halogens, 7

Atoms & Ions

100

This is the main difference between an atom and an ion

An atom is neutral whereas an ion is charged

200

This is the main difference between a cation and an anion

What is a positive ion and a negative ion

300

Justify why the ion K²⁺ could not exist under normal conditions

Potassium is an Alkali Metal, therefore it favours losing only 1 electron, not 2

400

Provide 2 examples of atoms or ions with the same number of electrons as P^3-

The answer must have 18 electrons

Options are: 

Cl^-, Ar, or S^2-

500

This is the ion that is present in our tap water to help strengthen our teeth

What is fluoride

Ionic Compounds

100

These are the two types of elements that combine to form ionic compounds

What are metals and non-metals

200

This explains how an ionic bond is formed

What is the transfer of electrons from a metal to a non-metal

300

This is the ionic formula for Aluminum oxide

What is Al₂O₃

400

This is the reason why two metals are not likely to form an ionic bond

Both metals will want to give away electrons

500

When comparing salt water and tap water, this is the better conductor because of all of the electrolytes present

What is salt water

Molecular Compounds

100

This is an explanation of what composes a molecular compound

What are two non metals combined

200

This is the name of the following polyatomic ion: 

OH^-

What is hydroxide

300

This is the name of the following compound

Na₂CO₃

What is Sodium carbonate

400

This molecule made of two of the same atoms joined by a covalent bond is often present as a gas

What is a diatomic molecule

500

This is the name of the following compound:

PCl₃

Phosphorous trichloride

Transition Metals

100

This is the explanation of a multi-valent transition metal along with an example

Metals that can exist as more than one stable ion

ex. Copper, Iron, Lead, Manganese, Tin

200

This is what we always include when naming a compound with a multi-valent transition metal

What is a roman numeral

300

This is the reason why we do not use roman numerals when naming all ionic compounds

Most ions exist in one form, whereas multi-valent ions have more than one form

400

This is the name of the following compound:

NiO

What is Nickel (II) oxide

500

This is the chemical formula of iron (III) chloride

What is FeCl₃
