Per NCERT, what is a CHEMICAL BOND?
AThe force that holds atoms together — formed when the total energy of the combined system is lower than the sum of individual atoms' energies
BThe repulsion between atoms
CAn external force from outside the atom
DA type of subatomic particle
Answer & Solution
Correct answer: A. The force that holds atoms together — formed when the total energy of the combined system is lower than the sum of individual atoms' energies
Per NCERT §9.4, chemical bond = attractive force from energy minimisation when atoms combine.
