how many protons, nnutrons, atomic mass, mass number, and charge to each of the following have?
for sodium i have
how do i find the number of neutrons cause im pretty sure mass number is protons plus neutrons
also is this right so far?

yes, protons + neutrons = mass #
protons = electrons for NEUTRAL atom

neutrons 23-11 = 12
mass number 23
atom has neutral charge

Now for a F ion
charge is -1, one more electron than proton
neutrons 19-9 = 10
mass # = 19
electrons 9+1 = 10

okay but why is it -1 charge?
- chem - Damon, Wednesday, January 7, 2009 at 8:10pm
An electron has charge of -1
A proton has charge of +1
