they need water, sunlight, and carbon dioxide
Answer:
group VI
Explanation:
there are 6 valance electrons and since valance electrons = group number, the group number will be 6
cr-52 is found in the greatest abundance.
Chromium has four naturally occurring isotopes cr-50, cr-52, cr-53, and cr-54 and average atomic mass of chromium is 51.996 amu.
Cr-52 because its mass number is closest to the actual atomic mass of Chromium (51.996).
- the more abundant an isotope is, the average will shift more towards its atomic mass. so its 51.996 .
- A heavy nucleus splits into two smaller nuclei.
- fusion is when is the name of the process where two nuclei join to create a new element
- fusion in the sun is the primary source for energy used by living organisms on Earth
- fusion process is occurring at the center of all active stars
