yes, protons + neutrons = mass #
protons = electrons for NEUTRAL atom
how many protons, nnutrons, atomic mass, mass number, and charge to each of the following have?
sodium atom
fluorine ion
stannic ion
for sodium i have
protons=11
electrons=11
neutral charge
how do i find the number of neutrons cause im pretty sure mass number is protons plus neutrons
also is this right so far?

Na
protons 11
neutrons 23-11 = 12
mass 22.99
mass number 23
electrons 11
atom has neutral charge
protons 11
neutrons 23-11 = 12
mass 22.99
mass number 23
electrons 11
atom has neutral charge
Now for a F ion
charge is -1, one more electron than proton
protons 9
neutrons 19-9 = 10
mass # = 19
electrons 9+1 = 10
charge is -1, one more electron than proton
protons 9
neutrons 19-9 = 10
mass # = 19
electrons 9+1 = 10
okay but why is it -1 charge?
An electron has charge of -1
A proton has charge of +1
A proton has charge of +1
