The atomic number of an isotope is the number of protons it contains, whereas the mass number is the total mass of the nucleus, which is the combined number of protons and neutrons in the nucleus. To find the number of neutrons, you must therefore subtract the atomic number of the isotope from the mass number of the isotope.
<span>In the above example, the atomic number is 8 and the mass number is 18. This isotope is known as O18. The number of neutrons in the isotope is: Mass number - Atomic number = Number of neutrons

2 is B. Water freezes and 4 is the rock breaks.
Answer: (A) The isolated chloroplasts will make ATP
Explanation:
The Thylakoid will receive hydrogen from the acid which is pumped across the thylakoid membrane, and the electrochemical proton synthesis of ATP begins in the stroma. Once the chloroplast has been transferred to the dark, high-energy electrons are loaded together with (H+) onto NADP+, converting it to NADPH.
