Question

a substance that consists of just one type of atom
a small particle that is a building block of matter
a combination of two or more substances physically blended together
anything that has mass and takes up space

1. what is a colloid?

a mixture where components are evenly distributed
a mixture where substances are not evenly spread out
a mixture where small particles remain dispersed throughout
a mixture where larger particles settle out over time

1. what is an element?

a substance with fixed composition

Explanation:

1. For the unlabeled matching terms:

• "a substance that consists of just one type of atom" defines an element.
• "a small particle that is a building block of matter" defines an atom.
• "a combination of two or more substances physically blended together" defines a mixture.
• "anything that has mass and takes up space" defines matter.

1. For question 6: A colloid is a type of mixture where small particles remain dispersed throughout the medium and do not settle out, distinguishing it from solutions (fully evenly distributed) and suspensions (particles settle over time).
2. For question 7 (partial): An element is defined as a substance that consists of just one type of atom, which matches the top unlabeled term.

Answer:

1. Matching terms:

• Element: a substance that consists of just one type of atom
• Atom: a small particle that is a building block of matter
• Mixture: a combination of two or more substances physically blended together
• Matter: anything that has mass and takes up space

1. Question 6: A mixture where small particles remain dispersed throughout
2. Question 7: A substance that consists of just one type of atom
