| 1 |
Can particles in a liquid flow? |
They can because particles can slide and move. |
| 2 |
Can the particles in a liquid move? |
The particles are touching, but can slide around. |
| 3 |
Can the particles in a solid be compressed? |
They cannot be compressed. |
| 4 |
Can the particles in a solid flow? |
It cannot flow either. |
| 5 |
Can the particles in gas be compressed? |
They can be compressed. |
| 6 |
Can the particles in gas flow? |
They can flow because they aren’t touching each other. |
| 7 |
Can the particles in gas move? |
Yes they spread out. |
| 8 |
Can the particles in the liquid be compressed? |
They cannot be compressed. |
| 9 |
Do the particles in a solid move? |
They don’t move around, but vibrate. |
| 10 |
How do you name a compound? |
Any compound made of a metal and a non-metal the name of the metal comes first, e.g. iron bromide. |
| 11 |
How many types of atom are there? |
There are 100 types of atom one for each of the 100 elements that exist naturally. |
| 12 |
How quickly diffusion happens depends on? |
Temperature particle size and state of matter. |
| 13 |
What are compounds made out of? |
Two or more different atoms strongly joined together and can be broken down into other substances. |
| 14 |
What are elements of the periodic table group in? |
Their group together by their properties. |
| 15 |
What are some example of elements? |
Hydrogen= H sodium=Na magnesium=Mg nitrogen=N. |
| 16 |
What can molecules be made of? |
Several of the same type of atom elements or two or more types of atoms compounds. |
| 17 |
What do the properties of a substance depend on? |
The shape and size of his particles, the arrangement of them how they move and how strong the force is between them are. |
| 18 |
What does a chemical formula tell you? |
The relative number of atoms of each element that is in the compound. |
| 19 |
What does density depend on? |
The massive particles and how closely they are together. |
| 20 |
What does density tell us? |
How heavy something is for its size. |
| 21 |
What does each type of atom have? |
A different property. |
| 22 |
What is a melting point? |
The temperature at which a substance melts. |
| 23 |
What is a molecule? |
More than one atom chemically joined together. |
| 24 |
What is a substance most dense at? |
A solid because the particles are compact. |
| 25 |
What is an atom? |
The smallest part of an element that can exist. |
| 26 |
What is an element? |
Cannot be broken down to other substances and is made of one type of atom only. |
| 27 |
What is boiling point? |
The temperature at which a substance boils. |
| 28 |
What is diffusion? |
Particles move about randomly in liquids and gases and spread out through mixtures. This process is called diffusion. |
| 29 |
What is H2O? |
Two hydration atoms for every oxygen atom. |
| 30 |
What is it called for every 10 atom? |
Monoxide. |
| 31 |
What is it called for every 2 atom? |
Dioxide. |
| 32 |
What is it called when a liquid turns into a gas? |
Evaporation. |
| 33 |
What is it called when gas turns into liquid? |
Condensation. |
| 34 |
What is MGCL2? |
Two chlorine atoms for one magnesium atom. |
| 35 |
What is NAOH? |
One sodium atom for oxygen and hydrogen atom. |
| 36 |
What is sublimation? |
Some substances don’t exist as liquids, but instead directly change state from solid to gas in a process called sublimation. |
| 37 |
What is the formula for calculating density? |
Density= mass/volume |
| 38 |
What is volume? |
It is the amount of space an object takes up measured in centimetres squared. |
| 39 |
What’s it called when solid becomes a liquid? |
Melting |
| 40 |
What’s it called when the liquid becomes a solid? |
Freezing. |
| 41 |
Where can names and symbols of elements be found? |
On the periodic table of elements. |
