Answer:
"Avogadro's law is an experimental gas law relating the volume of a gas to the amount of substance of gas present. The law is a specific case of the ideal gas law. A modern statement is: Avogadro's law states that "equal volumes of all gases, at the same temperature and pressure, have the same number of molecules."

Explanation: Nickel is element number 28 on the period table with a mass number 58 or 60, it exist in two forms and the phenomenon is known as isotopy
Definition of Isotopy is simply a phenomenon whereby elements exist in various forms that have the exact same chemical properties but different atomic mass.
58-Ni has atomic number 28 because that's the number o the element on the periodic table. Proton number is the same as atomic number and same as electron number for a neutral element or element without charge.
Mass number = Proton number (P) + Neutron number (N)
58 = 28 + N
N= 58-28
N= 30
58-Ni has 28 has the atomic number, proton number and electron number because it is a neutral atom but the neutron is 30 as shown in the calculation above.
60-NI+2 has a contrasting figure because the element has a charge of +2
Mass number= Proton + Neutron
60 = 28 + N
N= 60 - 28
N= 32
Electron = Proton - Charge
28 - (+2)
28 - 2
Electron = 26
The number of electron in 60-Ni +2 differs from 58-Ni because of the number of charge
Electron number differs from proton number in any element with a charge.
The term living thing refers to things that are now or once were alive, a nonliving thing is anything that was never alive.
