- This number is how many different kinds of atoms make up an element.
- One
- A group of symbols and numbers that shows what elements make up a compound.
- Chemical Formula
- H2SO4
- 2 hydrogen atoms, 1 sulfur atom, 4 oxygen atoms
- These are the properties of metals.
- Usually shiny, can be formed into sheets and wire and are good conductors of heat and electricity.
- This part of a solution makes up the smallest part.
- Solute
- The four groups all elements are sorted into.
- Metals, nonmetals, semimetals, noble gases.
- These particles of an atom swarm around the nucleus like a swarm of bees.
- Electrons
- One or two letters used to stand for the name of an element.
- Chemical Symbol
- A substance that cannot be broken down into any other substance by ordinary chemical means is this.
- element
- This is one way that compounds and mixtures are alike.
- They are both made up of different kinds of matter.
- These two particles are located in the center or nucleus of an atom.
- Protons and neutrons
- This is one way atoms can be joined together to form a compound.
- Two different kinds of atoms may share electrons.
- This is one way atoms may be joined together to form a compound.
- A positively charged atom and a negatively charged atom are attracted to each other and become chemically bonded.
- This part of an atom has a neutral charge.
- Neutron
- This is the center of an atom.
- Nucleus
- This part of a solution is the largest part.
- Solvent
- This describes how many different kinds of atoms make up a compound.
- Two or more
- A substance made up of two or more elements that are chemically combined.
- Compound
- This is one way that compound and mixtures are different.
- The parts of a mixture can be physically separated; a compound cannot.
- a mixture in which the different particles or kinds of matter are spread evenly throughout the mixture.
- Mixture
- This part of an atom has a positive electrical charge.
- Proton
- These are examples of mixtures.
- glass, air, brick, cement, asphalt, blood sweat, tears, saliva
- This is a particle made up of a group of atoms that are chemically bonded, or joined.
- Molecule
- This is one way that compounds and mixtures are different.
- The parts that make up a compound lose their original properties; the parts that make up a mixture keep their original properties.
- This is a way that compounds and mixtures are different.
- A compound can be written as a chemical formula; a mixture cannot.
- This part of an atom has a negative electrical charge.
- Electron
- This is a liquid mixture is which some particles are temorarily suspended in the mixture. Example salad dressing
- Suspension
