The number next to isotopes signifies the sum of the number of protons plus the number of neutrons in the nucleus of an atom.<span> An isotope is a version of an atom that has the same number of protons but different numbers of neutrons. Isotopes are very important in nuclear chemistry. A proton is a is a particle in the nucleus of an atom that has a positive charge. A neutron is also a particle in the nucleus of an atom, but it does not have an electric charge.</span><span>

The answer is B, the electrolysis of water. One cannot be the answer since the condensation of steam requires a loss of heat, an exothermic reaction. Numbers 2 and 3 cannot be correct either as they do not indicate energy in the chemical equation, and so it must be balanced throughout. Meaning that the only possible answer is B.
A.) The conversion factor is 1 amu =
To know how many amu in
grams of neutrons:
=1.00811 amu
b.) The mass in grams of one lithium ion which has an atomic weight of 6.94 amu.
=
c.) How many amu in 6.492x10^-23g potassium?
= 39.0957 amu
