|
to find # of protons... |
look at atomic # |
|
|
to find # of electons... |
look at atomic # (in a neutral atom, # of electrons = # of protons) |
|
|
# of neutrons = ... |
atomic mass - # of protons (atomic number) |
|
|
valence electrons |
the electrons in the last shell |
|
|
what is the relationship between family/group number and number of valence electrons? |
the group/family number is the amount of valence electrons -all elements in group 3 have 3 valence electrons |
|
|
what are the three types of elements |
metals metalloids non-metals |
|
|
similar physical properties that metals share |
-lustrous (shiny appearance) -malleable (can be hammered into thin sheets) -ductile (can be stretched into wires) -good conductors of heat and electricity -are solid at room temperature (except for mercury-Hg (liquid at room temperature)) |
|
|
similar physical properties that non-metals share |
-at room temperature some are solids, some are gases, and one is a liquid-bromine (Br) -not lustrous -brittle (non-malleable) -not ductile -poor conductors (carbon is the exception) |
|
|
similar physical properties that metalloids share |
-can have properties of both metals and non-metals e.g.) Silicon-Si: shiny and silver, but not malleable, and only a partial conductor of electricity |
|
|
chemical family/group |
set of elements in the same column -have similar physical and chemical properties |
|
|
what group/family are alkali metals in? |
group/family 1 |
