Answer:
Most organic compounds contain carbon and <u>hydrogen</u>.
Explanation:
Organic compounds are class of compounds which mainly constitute carbon and other elements like hydrogen, oxygen, nitrogen and sulfur etc.
In these compounds hydrogen is essentially present along with carbon as both make the basic organic class of compounds namely, Alkanes (saturated hydrocarbons), Alkenes and Alkynes (unsaturated hydrocarbons).
While remaining classes of organic compounds are derived from these three classes of hydrocarbons. Therefore, we can conclude that organic compounds are basically made up of carbon and hydrogen.
- The chemical symbol of the isotope boron-11 is ¹¹B.
- The atomic mass of the isotope boron-11 is equal to 11.009306.
- The abundance in nature of the isotope boron-11 is equal to 80.1%.
<h3>What is an isotope?</h3>
An isotope can be defined as the atom of a chemical element that has the same number of protons but different number of neutrons. This ultimately implies that, the isotopes of an element have the same atomic number (number of protons) but different atomic mass (number of neutrons).
In Chemistry, there are two main isotopes of boron and these include the following:
Boron-11 is the most stable isotope of boron and it is characterized by the following:
- The chemical symbol of the isotope boron-11 is ¹¹B.
- The atomic mass of the isotope boron-11 is equal to 11.009306.
- The abundance in nature of the isotope boron-11 is equal to 80.1%.
