Atoms generally have several possible transitions. In AA, the electrons of the atoms from the sample metal can be promoted to a higher orbital for a short amount of time by absorbing a set quantity of energy (i.e. Why does the sodium channel let the sodium ion into the cell, but not a postassium ion?Ītomic absorption spectroscopy is a technique used to determine the presence and concentration of a specific metal element in a sample. Why does the sodium channel let the sodium ion into the cell, but not a chloride ion? In this way, electrical signals can be transmitted along a neuron. This charge separation induces another channel to open, and so on, so that the charge is propagated along the cell membrane. The channel opens and a sodium cation is allowed into the cell, but not its counterion. A nearby cell membrane potential (a charge separation across the membrane) induces a change in the shape of a protein surrounding the channel. Voltage-gated sodium channels are part of the cell signaling system. Which of the following represents a Ca atom? a Sr atom? a Ba atom?Īrrange the following isoelectric ions (same number of electrons) in order of decreasing size: Check the periodic table after making your estimate.
