# What is the charge on a proton? watch

1. It isn't given to you in the data at the back of the paper - is it just the opposite of an electron i.e. 1.6X10^19 C??
2. 1.602*10^(-19)

1.602*10^(-19)
Oh yeah, missed that. when you multiply or divide by -1, never touch the index number... you'd need (1.602*10^19)/(1.602*10^-19) electrons to cancel out one proton otherwise... not a very stable atomic model.
4. 1 esu

I'm confused. Is it 1.6X10^+19 or 1.6X10-19??
6. charge on an electron = -1.6 * 10^-19
charge on proton = +1.6 * 10^-19

in other words the same magnitude as the charge on an electron just positive instead of negative. hope this clarifys.
7. The charge is quite simply +1. Never mind all that mumbo jumbo above. Keep it simple.
8. They're physicists vinny, us chemists have no place here
9. quite, that wont get you any marks on a physics paper, lol
10. electroc charge is measured in units called Coulombs. Hence the amount of charge on a proton is 1.6E-19 Coulombs.
To say the chagre is +1 is incorrect. What you can say though is that the 'relative' charge on the proton is +1.

Rather you than me!

Although, CCEA module 1 was terrible today.
