HELP PLEASEEE!! According to the quantum theory of atomic structure, an atom has all EXCEPT which of these characteristics?
A)
Electrons in atoms have quantized energies.
B)
The ground state of an atom represents the absence of quantized energy
Electrons in atoms are bound to the nucleus by electrostatic attraction
When electrons are excited, only discrete amounts of energy can be
absorbed
D)

Schrodinger and heisenberg developed an alternate theory about atomic nature that contradicted some of bohr's model of the atom. how do changes resulting from new technology and evidence affect the reputation of the atomic theory?

Identify one disadvantage to each of the following models of electron configuration: -dot structures -arrow and line diagrams -written electron configurations type in your answer below. (answer) -dot structures do not show the distribution of electrons in orbitals and take up a lot of space. -arrow and line diagrams take up a lot of space and make it difficult to count electrons. -written configurations make it easy to lose count of electrons and do not show the distribution of electrons in orbitals.
