Always two or more elements or different types of atoms that are chemically combined. Different properties from elements that make them up.
What is a compound?
This happens because water molecules are very attracted to each other and they stick together. (allows spider to walk on water)
What is Cohesion?
A mixture that does not have a uniform composition.
What is Heterogeneous?
Subatomic particles that have no charge and are found in the nucleus of an atom.
What are neutrons?
Elements that are solid and can be recognized by their luster or shine. Good conductors of electricity and heat. Many are malleable.
What are Metals?
A substance's ability to change into a new substance with different properties.
What is chemical property?
Water molecules are attracted to other surfaces. This allows water drops to spread without running off the surface.
What is adhesion?
Mixtures in which the particles of a material are spread throughout a liquid or gas but are too large to stay mixed without being stirred.
What are suspensions?
A negatively charged subatomic particle found in the electron cloud.
What is and electron?
The amount of protons in the nucleus of one of an elements' atoms.
What is the atomic number?
A characteristic of a substance that can be observed and measured without changing the identity of the substance
What is physical property?
A substance with definite chemical and physical properties.
What is a pure substance?
When one substance is dissolved in another
What are solutions?
A pure substance that is made up of only one type of atom.
What is a element?
An abbreviation that represents an element.
What is a chemical symbol?
Contains a variety of elements and compounds that are not chemically combined with each other.
What is a mixture?
Determines if a compound is an acid, neutral, or base.
What is PH?
When particles are spread within a liquid or gas but the particles are small and don't settle quickly.
What are Colloids?
The basic building blocks of matter because they are the smallest particle that can have the same properties as the stuff they make up.
What is an Atom?
Have some properties of metals and some of non-metals, less malleable than most metals, but not as brittle as nonmetals.
What are Metalloids?
A particle made up of two or more atoms that are joined together chemically
What is a molecule?
A mixture with evenly spread substances.
What is Homogeneous?
Subatomic particles that have a positive electric charge found in the nucleus of an atom.
What is a Proton?
Many of these are gases at room temperature. They lack luster and aren't very good conductors of electricity.
What are non-metals?
Stitch's experiment number
What is 626?
