Answer:
Atoms achieve configurations of noble gas electrons in simple covalent bonds by sharing electrons.
Explanation:
Valencia electrons are the electrons found in the last electronic layer (called valence orbitals). These electrons are what determine the ability of the atom to form bonds. When an element joins another, it does so through its valence electrons.
The covalent bond is the chemical bond between atoms where electrons are shared, forming a molecule. Covalent bonds are established between non-metallic elements, such as hydrogen H, oxygen O and chlorine Cl. These elements have many electrons in their outermost level (valence electrons) and have a tendency to gain electrons to acquire the stability of the electronic structure of noble gas. The shared electron pair is common to the two atoms and holds them together.
Then, atoms achieve configurations of noble gas electrons in simple covalent bonds by sharing electrons. In a simple covalent bond each of the atoms involved shares an electron for the formation of a shared pair, which from the formation will belong to both of the atoms. It occurs between Nonmetals and Nonmetals; Nonmetals and hydrogen; and between hydrogen and hydrogen.
Some examples of molecules with simple covalent bond are: H2 (where the two hydrogen atoms acquire electronic configuration of noble gas) and the chlorine molecule Cl2 (the two chlorine atoms have 8 electrons around them and therefore electronic configuration of Noble gas)
