Protons = Atomic number
Protons + Neutrons = Mass Number
Protons = 20
Neutrons = Atomic number - Mass number
Neutrons = 82 - 20 = 62
The neuron maintains a resting membrane potential. ... Because potassium is in high concentration inside the neuron, there is a concentration gradient attempting to force potassium out of the cell. Similar forces will attempt to move sodium ions into the neuron. so the answer is A ions
The answer is C
