Explanation:
Rather than remembering their charges just go for concept....
look for their electronic Configuration out of which if they r metals then their Valence shell orbital = charge of element
and for non metals
for ex
C(At. no. 6) - 1s² 2s² 2p² (here its Valence shell has 4,thus its Charge will be +4)
