---|---|
how are elements arranged on the periodic table | They are arranged in increasing atomic number, the atomic radius increses, and physical and chemical properties |
where are metals, nonmetals, and metaloids located on the periodic table | metals are on the right, the nonmetals are on the left, and the metaloids are in middle |
how do properties change across the periodic table | elements gain more electrons and protons as you move up the table, the atomic number also increases. |
what properties do metals share | shiny,luster,ductility,malleability, and conductivity |
what properties do metalloids share | bad conductors, most are gas at room temperature, can be solid but are dull in color, and have no luster |
what properties do halogens share | low melting and boiling points, they can be solid, liquids, and gases. |
what are Alkali Metals | an element in group one on the periodic table |
what are alkali earth metals | an element on group 2 of the periodic table |
what is a group | a column on the periodic table |
what are metals | an element that is genrally shiny, is easily pulled into wires or hammered into thin sheets, and is a good conductor of electricity and thermal energy |
what is a period | a row on the periodic table |
