Which change makes a new substance?
Chemical change. Physical Change does not change an objects chemical identity.
Name 3 signs of a chemical reaction
Colour Change, Temperature Change, Bubbles form, fizzing, new odour, new substance produced
What is the structure of an atom?
Made up of nucleus, protrons, neutrons and electrons. The protrons and neutrons are inside the nucleus and the electrons orbit it.
What is a chemical formula?
A shorthand of writing the name of a compound
What is a compound?
A compound is formed when two or more different types of atoms are chemically bonded (joined). A compound is a pure substance.
What’s an example of a compound?
Acetic Acid (C2H4O2) and Carbon Dioxide (CO2)
What is a mixture?
A mixture is made up of two or more substances that aren’t joined or bonded together.
What is an example of a mixture?
Honey and Tea, Cereal and Milk, Oil and Water
What are the two types of mixtures?
Homogeneous (of the same kind; alike.) and Heterogeneous (a process involving substances in different phases: solid, liquid, or gaseous).
What is physically mixed together?
Mixtures. Compounds are chemically mixed together.

hey
What is a reactant?
A reactant is a substance that takes part in and undergoes change during a reaction. For example Mageniusm and Carbon
What is an element?
Any substance that cannot be broken down into anything simpler, a similar substance. Made up of only one atom. type.
How many different types of atoms are there?
118
What’s the atomic number determined by?
The number of protons known as the atomic number reveals what type of atom it is and what element it is.
True or False, the number of the neutrons is the number of protons and electrons?
True the number of neutrons is the number of protons and electrons combined.
Which element has the most amount of neutrons?
Aluminium
What is the product?
They are species formed from chemical reactions
What is an example of a word chemical equation?
Magnesium + Oxygen –> MgO
Describe the arrangement of particles for all states of matter
Solid particles are tightly packed and often in a rectangle shape. Liquid particles are close together with no regular arrangement. Gas particles are well separated with no regular arrangement.
Does gas have mass?
No, but liquids and solids do.
Can solids be compressed?
No, but some liquids can and gases can as well.
Do liquids have a fixed shape?
No, but solids do. Gases do not.
Do atoms make up everything?
Everything except energy.
What is energy’s formula?
E = mc2 = Energy equals mass times the speed of light squared
Why is energy not made from matter?
Energy is not made of matter because it is released
How do I identify things on the periodic table?
The centre and the bottom row is dedicated to metals, non-metals are on the outer right side and metalloids are right next to the non-metals.
What is always on the left of an arrow?
Reactant, the product is on the other side
Why isn’t energy made up of matter?
Energy doesn’t have a mass
