Isotopes of an element have nuclei with the same number of protons and the same number of neutrons.
Isotopes of an element have nuclei with a different number of protons, but the same number of neutrons.
Isotopes of an element have nuclei with a different number of protons, but the same number of electrons.
Answer:isotopes of an element has same number of proton but different number of neutron.
Explanation:
Isotope: The atoms of element having same atomic number but different mass number are called isotope.
Hydrogen has three isotopes called as
1.protium
2.duetrium
3.tritium
All of the isotopes of hydrogen have same atomic number but different masses 1,2,3 respectively.
Isotopes have same outermost shells there for having same chemical properties.
Isotopes have different nuclie due which they have different physical properties.
Tritium the 3rd isotop having diffrent prton to neutron ration emitts radiation there it in traces.
Answer: its neutrons

Answer:
Explanation:The buffer is a mixture of ammonia (NH3) and ammonium (NH4+). ... Since ammonia (NH3) is a weak base, it will have a pH above 7 and since ammonium (NH4+) is a weak acid, it will have a pH below 7. Ammonia (NH3) is a weak base and ammonium (NH4+) is a weak acid. Ammonia (NH3) is the conjugate base of ammonium (NH4+).
Ammonium ion, in collaboration with ammonia, acts as a buffer solution. The point at which it becomes a buffer is when the concentrations of NH3 and NH4+ are equal, typically around a pH of 9.25, enabling them to neutralize other strong acids or bases to stabilize the pH.
Ammonium ions (NH4+) act as a buffer solution in conjunction with a weak base (ammonia, NH3). This system can balance the pH of a solution by either absorbing excess hydronium ions (H3O+) when the solution becomes too acidic or by producing more when the solution becomes too basic. The point at which the ammonium ion acts as a buffer solution is the pH at which the concentrations of the weak base (NH3) and its conjugate acid (NH4+) are equal. This is typically around a pH of 9.25, where the ammonium ion and its conjugate base, ammonia, can effectively neutralize additional strong acids or bases, thereby stabilizing the pH of the solution.
