In general chemistry, isotopes are substances that belong to one specific element. So, they all have the same atomic numbers. But they only differ in the mass numbers, or the number of protons and neutrons in the nucleus. In a nutshell, they only differ in the number of neutrons.
For Nickel, there are 5 naturally occurring isotopes. Their identities, masses and relative abundance are listed below
To determine the average atomic mass of Nickel, the equation would be: Average atomic mass = </span>∑Abundance×Atomic Mass
Using the equation, the answer would be: Average atomic mass = 57.9353(68.0769%) + 59.9308(26.2231%) + 60.9311(1.1399%) + 61.9283(3.6345%) + 63.9280(0.9256%)
A chemical reaction that removes electrons from an atom is called "O<span>xidation". The term came from late 18th century from French. When the electrons are removed from an atom it increase its valence.</span>
The moles of any substance are equal to the substance's mass divided by its molar mass. Therefore, in order to calculate the moles of copper, you would divide the reacted mass by 63.55
