States of Matter
The state of matter that has a definite shape and closely packed particles
What is a solid?
A substance with compounds, molecules and atoms.
What is a mixture?
The graphic organiser of all the elements.
What is the periodic table?
The positive particles in the nucleus of an atom.
What are protons?
The name of the substances that are combined to make a reaction.
What are reactants?
The temperature where a liquid becomes a gas.
What is boiling point?
A substance that contains atoms of multiple different elements, shown by joined dots of different sizes or colours.
What is a compound?
The element on the periodic table with an atomic number of 6.
What is Carbon?
The layers of electrons on an atom.
What are electron shells?
When a substance is reacted with oxygen under heat.
What is burning?
When particles start to move more freely and spread apart on the bottom of the container.
What is melting? (solid to liquid)
A drawing of joined circles of the same size and colour.
What is the particle model of a molecule?
The way to show an element using the particle model.
What is a single dot?
The number of protons in the nucleus of an atom.
What is atomic number?
Three of the signs of a chemical change.
What is: Light/Sound/Smell/Gas/Precipitate/Temperature/Colour?
To change a solid to a liquid, this needs to be decreased.
What is pressure?
Is HCl a compound or a molecule?
compound
Two properties of metals.
What is: Lustrous/Malleable/Hard/Ductile/Sonorous/Conductive
The stabilising particle in an atom allowing for higher atomic numbers.
What is a neutron?
Boiling water.
What is physical change?/What is NOT an example of chemical change?
Explain why a solid might increase in size as the temperature changes.
Heating a solid causes the space between the particles to increase, making the solid expand slightly.
Does a compound share the same properties as the elements it is made of?
No.
Elements that are found to the top and right of the periodic table.
What are non-metals?
This is the way we calculate the atomic mass of an atom.
The combined number of protons and neutrons in the nucleus.
What is chemical change?
When two or more substances combine to create new substances.
