Explanation: Please mark branliest.
I am going to be honest i’m good at chemistry but i need the point cause i need help on my history work
I am not sure about my answer, but I think that it's density allows it to fall to the ground/floor.
Answer:
1 A true
B False
C not sure about it False
D False
Answer:
D. The behavior of an atom's electrons can be described by circular orbits around a nucleus.
Explanation:
<em>Which of the following statements is INCORRECT? </em>
<em>A. It is not possible to know the exact location of an electron and its exact energy simultaneously.</em> CORRECT. This is known as the Heisenberg's uncertainty principle.
<em>B. The energies of an hydrogen atom's electrons are quantized.</em> CORRECT. According to the modern atomic model, the energy levels are quantized, that is, they have a discrete amount of energy.
<em>C. The wave mechanical model correctly predicts all the energy states and the orbitals available to an electron in an hydrogen atom.</em> CORRECT. The characteristics of the energy levels are explained by Schrödinger's wave equation.
<em>D. The behavior of an atom's electrons can be described by circular orbits around a nucleus.</em> INCORRECT. This was postulated by Bohr's atomic model but it is now considered to be incorrect.
<em>E. Electrons have both wave and particle properties.</em> CORRECT. This is what De Broglie called wave-particle duality.
