Carbon -13 has 7 neutrons and carbon -12 has six neutrons. Carbon -12 is the most common isotope of Carbon. Carbon -14 is radioactive and vary rare. The symbols for the isotopes of Carbon atoms shown here indicate they each have six protons but mass numbers of 14, 13, and 12. Hope this helps. :)
I'm not sure what it asks, but it answers
- how many protons are in the nucleus
- how many electrons are in the atom
- where it sits in the periodic table
- If the periodic table is divided in the modern way, it gives a good indicator of whether you are speaking about a metal, a non metal or neither.
Answer:
In cellular respiration, cells use <u>oxygen</u> to release energy stored in <u>glucose</u>.

A pure crystalline substance is a substance with an almost perfect regular and periodic pattern in a solid state. This makes this type of substance a hard one compared to an amorphous substance which is soft because of the irregular pattern within.
