How does the size of oxygen's nucleus affect the distribution of electrons in the water molecule<span>?
The </span>oxygen's nucleus<span> contains eight protons.</span>
<span>Tropical Savanna is being converted to a desert biome. When the surface level begins to face advanced erosion, there is less vegetation to hold water in their roots. As the top layer continues to dry out, any new seed being brought in naturally will not be able to grow due to a lack of moisture.</span>
The answer should be the third option "number of protons and neutrons." The atomic mass of a element is equal to the amount of protons, and neutrons added together in that element. So for example if we are trying to find the atomic mass of hydrogen you would add the total amount of protons and neutrons together to find it's mass although it doesn't equal the exact amount of it's mass but it's close.
Hope this helps.
