Reactivity
elements tend to be more reactive the farther they are from the centre of the Periodic Table (and the closer to the bottom left and upper right corners)
what are the metal groups
alkali metals, alkali earth metals, transition metals, and the two bottom row
alkili metalsk properties?
he most reactive metals (react rapidly with water)
silver in colour, are soft, and have low densities
alkili earth metal properties
somewhat reactive (less than Alkali metals) silver in colour, are soft, and have low densities
transitional metal properties
not as reactive as Alkali and Alkali Earth Metals
different colours, varying hardness, and have high densities
Non metals group properties
poor conductors of electricity and heat
some are solids, some are gases, one liquid (Br)
halogens non metal properties
most reactive non metals
noble gases non metal properties
inert, very non reactive
metalliods non metal properties
have metal and non-metal properties
(i.e. slightly lustrous and brittle)
what is the octet rule?
when ur valience electrons have eight electrons
how do alkili metals tuen into a ocetet
there valenice electron is one, so when u lose that one u get a ocetet
how do u turn halogens into ocetet
they have 7 valence electrons, they just need to gain one ,they take atoms away
t/f? Atoms in the same period have the same number of energy levels, The lower an atom is on the periodic table, the larger it is
yes true lol
