c1.2 - the periodic table

the middle section of the periodic table shows the [blank_start]transition metals[blank_end] .

the columns represent the [blank_start]groups[blank_end]

the rows represent the [blank_start]periods[blank_end]

can group 0 also be written as group 8

group [blank_start]8[blank_end] are very [blank_start]stable[blank_end] and very un - [blank_start]reactive[blank_end]. they are [blank_start]noble[blank_end] gases

group 1 are [blank_start]alkaline[blank_end] metals. they are very [blank_start]reactive[blank_end]

metal + oxygen = metal [blank_start]oxide[blank_end]

metal + [blank_start]water[blank_end] = metal [blank_start]hydroxide[blank_end] + hydrogen

depending on which [blank_start]group[blank_end] it is, it shows the amount of [blank_start]electrons[blank_end] which will be on the outer shell.

if an element has 4 electrons the structure would be [blank_start]2:2[blank_end]

if an element has 19 [blank_start]electrons[blank_end] the structure would appear like [blank_start]2:8:8:1[blank_end]
