Answer:
True. Covalent bonds are formed when atoms share electrons to achieve a stable electron configuration. The arrangement of the outermost electrons, also known as the valence electrons, determines the bonding behavior of atoms.
Step-by-step explanation:
In a covalent bond, atoms share one or more pairs of electrons to fill their outermost energy levels. This sharing allows each atom to achieve a more stable electron configuration, usually by filling their valence shell with eight electrons (the octet rule) or two electrons (in the case of hydrogen).
The arrangement of the outermost electrons affects the strength and type of covalent bond formed. For example, in a single covalent bond, two atoms share one pair of electrons. In a double covalent bond, they share two pairs of electrons, and in a triple covalent bond, they share three pairs of electrons.
Overall, the arrangement of the outermost electrons plays a crucial role in determining the nature and properties of covalent bonds.
