litmus test | solutions react chemically with paper -acids turn red on blue paper -bases turn bule on red paper |
pH test paper | solutions react chemically with the paper; color will indicate the level of acidity or alkalinity |
acids and bases are ________ that seperate into ________ when disoloved in water | 1.) ionic compounds 2.) ions |
when both acids and bases disollve in water they... | conduct electricity |
tHE STRENGTH OF ELECTRICITY DEPENDS ON | THE AMOUNT OF IONS |
acids are | acidic solutions |
bases are | alkiline solutions |
Acid- | taste sour, (examples are fruit juices and sodas,react with metals and other substances. They are corrosive and "eat away" at materials |
Acids produce____ions when dissolved in water | Hydrogyen (H+) |
Bases- | taste bitter and feel slippery, (examples:soaps and shampoos)bases do not react with metals in the same way. they can corrode with other substances |
bases produce_____ when dissolved in water | hydroxide (OH-) |
when acids and bases mix they | nuetralize! |
Acid+base= | water+ a "salt" |

in chemical formuls what item is written first? | the positive ion |
what particles of the atom are located in the nucleaus? | protons and neutrons |
durring a chemical reaction | matter cannot be created nor destroyed |
an ionic bond is the attraction between | Oppisitley charged ions |
what is the total number of valence electrons an atom needs to become happy | 8 |
the atomic number is the number of | protons in the nucleus of an atom |
when alkili metal in group 1 forms an ionic bond it | loses one electron |
an ionic bond must contain | a metal and a nometal |
an extremely reactive family; gains one valence electron when bonding | halogen family(group 17) |
an extremly reactive family ; each loses one valence electron when bonding | Alkili metals(group one) |
a family of non reactive elements ; each have already a complete outer ring of valence electrons | nobel gases (group 18) |
