What is an organic compound? any compound where there are metals bound to other types of atoms compound grown with organic farming methods any compound isolated from living organisms any molecule that is made mostly of carbon with no metals in it anything that is a salt obtained from organic creatures

Any molecule that is made mostly of carbon with no metals in it.

Explanation:

The previous definition of organic compounds was the compounds which are obtained from any living organism. However after the laboratory synthesis of urea, the definition was no longer true.

According to chemistry, an organic compound is one which is made up of carbon [generally bonded to non metals like hydrogen, nitrogen, oxygen, halogens, sulfur, phosphorous etc]. Carbon has the distinct ability to form bonds with other carbon atoms (catenation) which results in formation of large number of this class of compounds.

explanation:

let the different atoms be x and y. each with four protons and same mass will be represented as follows.

mass number is number of protons + number of neutrons.

            and  

since, it is given that one has a negative charge while the other is neutral. therefore, there will be increase in number of protons and the atom will be represented as follows.

according to periodic table, mass number of beryllium is 9 and it has atomic number 4 so, the atoms will be and .  

the protons and neutrons will be located inside the nucleus whereas the electrons will be revolving around the nucleus.
