Detailed explanation-1: -Answer and Explanation: When two atoms form a chemical bond, they either share electrons or transfer them to make a new compound. Electrons are the negatively charged particles that orbit the nucleus of an atom in various energy levels.
Detailed explanation-2: -A chemical bond resulting from the sharing of electrons between atoms is called a covalent bond.
Detailed explanation-3: -Definition: Octet Rule Thus, an atom continues to form bonds until an octet of electrons is made. This is known as octet rule by Lewis. Figure 1: Bonding in H2 and methane (CH4) A hydrogen bonds with each of the four valence electrons of a carbon meaning that four hydrogens can bond with one carbon.
Detailed explanation-4: -Elements forming covalent compounds achieve noble gas configuration by sharing electrons within the atoms, unlike ionic compounds which achieve the noble gas configuration either by gaining or losing electrons from the outermost electron shell.
