1 Which statement describes the modern model of the atom?
(1) The atom has a small, negatively charged nucleus.
(2) The atom is a hard, indivisible sphere.
(3) Electrons are positive particles in the atom.
(4) Electrons in the atom have wave-like properties.
Solution:
The modern model of the atom states that electrons have wave-like properties. Choice 4 is the correct answer.
Choice 1 is wrong because the nucleus has a positive charge, not negative. Choice 2 was one of the earliest models of atom. Choice 3 is wrong because electrons are negative, not positive.
