Wellington’s victory at Badajoz paved the way for a decisive Allied advance into Spain, culminating in the triumph at Salamanca and the rout of French forces at Vitoria in 1813. Though marked by brutal combat, destruction, and looting,...

Covalent bonds form when atoms share electrons to complete their valence shells, creating strong and directional interactions.

NaCl forms when sodium transfers an electron to chlorine, creating Na⁺ and Cl⁻ ions that attract each other to form a stable ionic lattice.

The Kossel-Lewis approach introduced the concept of ionic and covalent bonds. It emphasizes the role of electron transfer or sharing between atoms to achieve noble gas configurations

This theory states that valency arises from the tendency of atoms to achieve a stable electronic configuration by gaining, losing, or sharing electrons to form bonds
