The subunits of nucleons are called quarks
<span>Step 1)
write out all aqueous compounds as ions
2H+ (aq) + 2Br- (aq) + Ba2+ (aq) + 2OH- (aq) --> 2H2O (l) + Ba2+ (aq) + 2Br- (aq)
Step 2)
Cross out the spectator ions (ions that appear on both sides of the reaction)
2H+ (aq) + 2OH- (aq) --> 2H2O (l)
what you have left is the net ionic equation.
I hope this helped.</span>
Pb2 has the greatest molecular mass
