Web27 sep. 2024 · Ionic Currents: the cardiac action potential is produced by the interplay of many different ionic currents. Most are selective for either Na, K, Ca, or a mixture of Na & K. Each current has its own “historical” name (or names) & is caused by the time-dependent opening of voltage-gated channels. WebActinide Contraction. The atomic size/ ionic radii of tri positive actinides ions decrease steadily from Th to Lw due to increasing nuclear charge and electrons entering the inner (n-2) f orbital. This gradual decrease in the size with an increasing atomic number is called actinide contraction like lanthanide contraction.
