| the nucleus of an atom is made up of | protons + neutrons |
| all elements are mixtures of | isotopes |
| the chemical behavior of different elements is determined by the number of electrons in the | outermost |
| solutions characterized by the formation of hydroxide ions are | Acids |
| a combination of two or more components that retain their identity is an | mixture |
| densely packed, ever- changing of state releases thermal energy | condisation |

| glass is an example of | solid + liquid |
| a molecule of chlorine gas is made up of pairs of chlorine atoms in which each atom shares one of its seven electrons to form a | covalent bonds |
| how many physical states is matter found on earth | 4 |
| Tomatoes are ? PH of 4 | acid |
| the basic building blocks of matter | atoms |
| the nucleus of an atom is made up of | protons + neutrons |
| many elements are mixtures of | solids |
| chemical behavior is determined by the number of electrons located in the | outermost layer |

| Increases rate of chemical weathering of rock | increasing toal surface area |
| Happens when a river enters a large body of water | slows down- makes deposits |
| Color of soil is | determined by comp + climate |
