Question

Atom seeking atom: Discuss each atom's role in chemical bonding. Mention the number of valance electrons in each atom, how they combine, and what type of bond they form. Also include how carbon is found in all living things. Include a picture. (the electron–dot diagram)
HELP PLEASE I DONT UNDERSTAND AT ALL

Answer 1

There is a missing Diagram here. I can't know which atom to describe if there is no specific atom in a figure.

But the 2nd question is answerable: Carbon is found on all living things because all Organic Molecules—which is important in the formation of life—have carbon in them. Organic molecules are the chemicals of life, compounds composed of more than one type of element, that are found in, and produced by, living organisms. The feature that distinguishes an organic from inorganic molecule is that organic contain carbon-hydrogen bonds, whereas inorganic molecules do not. The four major classes of organic molecules include carbohydrates, proteins, lipids and nucleic acids.

Carbon is a very unique atom. It can both lose or gain four electrons to obtain an octet. It can form four bonds to make an octet and have a formal charge of 0. The most important thing about carbon is its ability to chain to itself, making it the basis for organic chemistry and life. A few carbon compounds

Answer 2

A chemical bond is an attraction between atoms that allows the formation of chemical substances that contain two or more atoms. The bond is caused by the electrostatic force of attraction between opposite charges, either between electrons and nuclei, or as the result of a dipole attraction. The strength of chemical bonds varies considerably; there are "strong bonds" such as covalent or ionic bonds and "weak bonds" such as dipole–dipole interactions, the London dispersion force and hydrogen bonding.
Since opposite charges attract via a simple electromagnetic force, the negatively charged electrons that are orbiting the nucleus and the positively charged protons in the nucleus attract each other. Also, an electron positioned between two nuclei will be attracted to both of them. Thus, the most stable configuration of nuclei and electrons is one in which the electrons spend more time between nuclei, than anywhere else in space. These electrons cause the nuclei to be attracted to each other, and this attraction results in the bond. However, this assembly cannot collapse to a size dictated by the volumes of these individual particles. Due to the matter wave nature of electrons and their smaller mass, they occupy a much larger amount of volume compared with the nuclei, and this volume occupied by the electrons keeps the atomic nuclei relatively far apart, as compared with the size of the nuclei themselves.
In general, strong chemical bonding is associated with the sharing or transfer of electrons between the participating atoms. The atoms in molecules, crystals, metals and diatomic gases— indeed most of the physical environment around us— are held together by chemical bonds, which dictate the structure and the bulk properties of matter.
