Year 10 Revision

Atomic Structure

100

Name the three types of subatomic particles.

protons

neutrons

electrons

200

What charge does a group 2 metal have as an ION?

2⁺

300

If an element has an atomic number of 7 and a mass number of 15, how many protons, neutrons and electrons does it have?

7 protons

7 electrons

8 neutrons

400

How many valence electrons does Neon have (group 18)?

Neon has 8 valence electrons which makes its outer shell full. This is significant as it means the element is unreactive - it does not need to bond with another atom to be stable.

500

Identify an element with similar chemical properties to fluorine and explain what it is about their atomic structure that explains these similarities.

Any element from the same group (group 7 - halogens) would have similar chemical properties as its the number of valence shell electrons that determines how elements react. This could be Cl, Br, I

Periodic Table

100

The periodic table is arranged in order of increasing....?

Atomic number

200

Describe what happens to atomic radii as you move down a group of the periodic table.

atomic radius increases (because extra electron shells are added - the period represents the number of electron shells)

300

Group 16 consists of metals or non-metals?

Non-metals

400

What are the two ways we organise the Periodic Table?

Groups (vertical) and Periods (horizontal)

500

An atom has an electron configuration of 2,8,3. What group does it belong to?

Group 3.

Ions

100

Explain WHY ions form?

The Octet rule, atoms want a FULL valence shell of electrons to be stable.

200

Describe 2 properties of ionic compounds like salt (NaCl)

hard

high melting point

brittle

conducts electricity only when molten or aqueous

300

Write the ion to represent Nitrogen (N). You may use your periodic table.

N^3-

400

Write the ionic formula for the compound formed between the ions Ba²⁺ and F^-

BaF₂

500

Determine the correct ionic formula for potassium sulfate 

Sulfate = SO₄^2-

K₂SO₄

Bonding

100

What are three types of bonds?

Ionic, Covalent and Metallic.

200

Explain two properties of a covalent bond.

Low melting and boiling point

Poor conductors

Usually insoluble

Typically gas or liquid at room temp.

300

Explain how a covalent bond forms?

Covalent bonding occurs between two non-metals when a pair of SHARED electrons creates the bond.

400

Give two examples of a covalent compound.

H20 or CO2 or H2 or O2

500

You find an unknown substance. It does not conduct electricity other than when it is in water. If you hit it with a hammer it will shatter. What bond does the substance have? 

Ionic Bond

Random

100

What is a group of Panda's called?

An Embarrassment.

200

What was Pixar's first feature length movie?

Toy Story (1995)

300

What was Disney's first film?

Snow White (1937)

400

What colour does Red + Green make?

Brown

500

What does the “G” in 5G stand for?

Generation.
