One of the Main Problems with the Bohr Model of the Hydrogen

question 49

Multiple Choice

One of the main problems with the Bohr model of the hydrogen atom when compared with the results of the methods of quantum mechanics used to describe atoms,was that the Bohr model predicted

• A)the ground state angular momentum was L = 1 .
• B)the frequency of the radiation emitted when an electron "jumps" from one allowed orbit to another was hf = E_i − E_f.
• C)the potential energy function for the hydrogen atom was given by V(r)= −ke²/r.
• D)the energy of the ground state of the hydrogen atom was E_n = −13.6 eV.

Describe the process of synaptic transmission, including the role of neurotransmitters and the sequence of events from neurotransmitter release to response in the postsynaptic cell.

Understand how the strength and frequency of stimuli affect the generation of action potentials and the communication of information within the nervous system.

Explain the differences between electrical and chemical synapses and their functional implications.

Describe the variability in postsynaptic responses depending on the type of neurotransmitter and the receptors involved.

Definitions:

Nerves

Bundled axons that form neural cables connecting the central nervous system with muscles glands, and sense organs.

Axons

The long, slender projections of a neuron that transmit electrical impulses away from the neuron's cell body to other neurons, muscles, or glands.

Interneurons

Neurons located in the central nervous system that process and relay information between sensory neurons and motor neurons.

Endorphins

Substances produced by the body that bind to brain receptors to diminish the sensation of pain and induce a state of intense happiness.
