6Group 1,(Alkali Earth Metals) are very [blank_start]reactive[blank_end] because the only have [blank_start]1[blank_end] valence electron and so during a reaction they only need to [blank_start]lose one[blank_end] electron to have a [blank_start]complete[blank_end] outer shell.

13Every [blank_start]substance[blank_end] in the universe is made up of [blank_start]matter[blank_end] that can exist in a number of different forms called states. Almost all matter on Earth exists in three different states: [blank_start]solid[blank_end], [blank_start]liquid[blank_end] and [blank_start]gas[blank_end].
- Asubstance
- Bmatter
- Csolid
- Dliquid
- Egas
14Solids such as ice have a very [blank_start]definite[blank_end] shape that [blank_start]cannot[blank_end] easily be changed. They take up a [blank_start]fixed[blank_end] amount of space and are generally [blank_start]not[blank_end] able to be compressed.
Most solids [blank_start]cannot[blank_end] be poured, but there are some, such as salt, sand and sugar, that can be.- Adefinite
- Bcannot
- Cfixed
- Dnot
- Ecannot
15Water is a [blank_start]liquid[blank_end] and its shape [blank_start]changes[blank_end] to that of the container in which it is kept. Like [blank_start]solids[blank_end], liquids take up a [blank_start]fixed[blank_end] amount of space.
If a liquid is poured into a glass, it will take up the [blank_start]shape[blank_end] of the glass. If you continue to pour, it will eventually overflow onto the bench or floor.- Aliquid
- Bchanges
- Csolids
- Dfixed
- Eshape
16[blank_start]Gases[blank_end] spread out and will not [blank_start]stay[blank_end] in a container unless it has a lid. Gases move around, taking up all of the available space. This movement is called [blank_start]diffusion[blank_end]. In the illustration below, iodine gas is being formed and is spreading, or [blank_start]diffusing[blank_end], throughout the gas jar.
- AGases
- Bstay
- Cdiffusion
- Ddiffusing

18Particle Model: A description of moving particles that make up matter and how they behave.
According to the particle model:- Aall substances are made up of tiny particles
- BThere are 50 particles in one substance
- Cthe particles are attracted towards other surrounding particles
- DParticles always are still.
- EParticles are always moving,
- Fthe hotter the substance is, the faster the particles move.
- GIf the substance is cold it slowly degenerates.
19In solids the particles are very [blank_start]close[blank_end] together, so they [blank_start]cannot[blank_end] be compressed. The attraction between neighbouring particles in a solid is usually [blank_start]strong[blank_end]. Because there are such strong bonds between the particles, solids usually have a [blank_start]fixed[blank_end] shape and a constant [blank_start]volume[blank_end]. The particles in solids [blank_start]cannot[blank_end] move freely; instead they vibrate in a fixed position.
- Aclose
- Bcannot
- Cstrong
- Dvolume
- Efixed
- Fcannot
20In liquids the particles are held together by [blank_start]attraction[blank_end], but the bonds between them are not as [blank_start]strong[blank_end] as those in [blank_start]solids[blank_end]. The weak particle attraction allows the particles to [blank_start]roll[blank_end] over each other, but they can’t ‘[blank_start]escape[blank_end]’. For this reason, liquids have a [blank_start]fixed[blank_end] volume but the rolling motion of the particles allows them to take up the [blank_start]shape[blank_end] of their container. As in solids, the particles in liquids are still very close together; liquids [blank_start]cannot[blank_end] be compressed into smaller spaces.
- Aattraction
- Bstrong
- Csolids
- Droll
- Eescape
- Ffixed
- Gshape
- Hcannot
21The particles in a [blank_start]gas[blank_end] have much more energy than those in solids or liquids, and they are in constant motion. The attraction between the particles in a gas is so [blank_start]weak[blank_end] that they are able to move freely in all directions. They spread out to take up any [blank_start]space[blank_end] that is available. This means that gases have [blank_start]no[blank_end] fixed shape or volume. Because of the large spaces between particles, gases can be [blank_start]compressed[blank_end].
- Agas
- Bweak
- Cspace
- Dno
- Ecompressed
22Diffusion Is
- AThe bonds of an atom
- BThe aftermath of a chemical reaction
- Cthe spreading of one substance through another.
- DThe spreading of one atom through another
23A change of state involves the [blank_start]heating[blank_end] or [blank_start]cooling[blank_end] of matter. As a substance is [blank_start]heated[blank_end], energy is transferred to it. When a substance [blank_start]cools[blank_end], energy moves away from it to another substance or to the environment. The change in [blank_start]energy[blank_end] causes the particles in the substance to move at different speeds.
- Aheating
- Bcooling
- Cheated
- Dcools
- Eenergy
