Elements, Compounds, Mixtures Milestone Review

• a substance that cannot be broken down into any other substance by physical or chemical means

• a substance that appears to be a single substance, but actually composed of two or more substances that are distributed evenly among each other

• a single kind of matter that is pure meaning it always has the same formula

• a mixture of different elements and compounds all together

• a mixture of protons and electrons that have no meaning

• a mixture of protons, neutrons and electrons that can be broken down further

• the basic particle from which all elements are made

• the largest substance which makes up elements

• It is only an element

• It is an elements, but also a molecule when two or more oxygens are bonded together

• It is only a molecule

• It is a molecule only because when two or more oxygen atoms are bonded together is makes an element

• A single kind of matter that is not pure, the make up is not specific

• A kind of matter that has a specific make up but it is not the same composition each time

• A single kind of matter that has a specific making; meaning it always has a specific makeup or composition

• No elements are the only pure substances

• No compounds are the only pure substances

• Yes compounds and elements are each a single type of matter with specific makeup and specific properties

• Yes compounds and elements are many different types of matter without specific makeup or properties

• During physical bonding, elements keep their properties when compounds are formed.

• During chemical bonding, new substances with different properties are formed.

• During physical bonding, new substances with different properties are formed.

• During chemical bonding, elements keep their properties when compounds are formed.
