What are the main concepts of atomic models, chemical bonds, and polarity?
I - The atomic models are theoretical representations of the structure of atoms, and they have evolved over time, from the Dalton model to the quantum model.
II - Chemical bonds are the forces that hold atoms together in molecules, and they can be classified as ionic, covalent, or metallic.
III - Polarity is a property of molecules that arises from the unequal distribution of electrons between atoms, and it can be measured by the dipole moment.
a) Only I is correct.
b) Only II is correct.
c) Only III is correct.
d) I and II are correct.
e) I, II, and III are correct.

A resposta correta é a alternativa E) I, II e III estão corretas. I - Os modelos atômicos são representações teóricas da estrutura dos átomos e evoluíram ao longo do tempo, desde o modelo de Dalton até o modelo quântico. II - As ligações químicas são as forças que mantêm os átomos juntos em moléculas e podem ser classificadas como iônicas, covalentes ou metálicas. III - A polaridade é uma propriedade das moléculas que surge da distribuição desigual de elétrons entre os átomos e pode ser medida pelo momento dipolar.
