An alpha particle is identical to a helium atom that has been stripped of its two electrons
Answer:
2) total number of protons
Helium has an atomic number of one, and has only one proton in its nucleus.
Oxygen has an atomic number of 8 and an atomic mass of 16. From this we know that the atomic number measures the number of protons, and the atomic mass is the overal sum of protons and neutrons.
A buffer is a solution which resists changes to it pH when a small quantity of acid or base is added to it.
<h3>What is a buffer?</h3>
A buffer is a solution which resists changes to it pH when a small quantity of acid or base is added to it.
Buffers are made from solutions of weak acids and their salts or weak bases and their salts.
<h3>What is pH?</h3>
The pH of a solution is the negative logarithm to base 10 of yhe hydrogen ion concentration of the solution.
Solutions of low pH have high concentration of hydrogen ions while solutions of high pH have high hydrogen ion concentration.
