20 isotopes
Actinoids is series of chemical elements; lanthanoids is an other different series.
Common elements in a decay chain include uranium, thorium, radium, radon, and polonium. These elements undergo radioactive decay to produce different isotopes and elements through a series of transformations.

The activity series in chemistry helps predict how elements will react with each other in redox reactions. Elements higher in the series are more reactive and will replace elements lower in the series in a reaction. By comparing the positions of elements in the activity series, one can predict which elements will undergo redox reactions and the direction of the reaction.
An example of a series of words that appear in a definite sequence is a complete sentence. Depending on the language, different parts of speech have to be placed in a specific order for the sentence to be intelligible.
In a series circuit, current will remain the same through all elements, and the voltage drop across elements will vary. So the answer is: it doesn't.
In series resonance, the inductance and the capacitance are connected in series, but in parallel resonance they are connected in parallel. In series resonance, at an input signal with a frequency equal to resonance frequency, the total impedance of both inductive and capacitive elements together is zero (or they appear as short circuits) unlike the parallel resonance case in which it is infinite and they appear as an open circuit.
Such a list is called a reactivity series or an activity series. It is used to predict the likelihood of different elements or metals undergoing specific chemical reactions based on their reactivity.
it was in the 4th series he was introduced
There are 15 elements in the actinoid series, also known as the actinides. These elements follow actinium in the periodic table and include elements such as thorium, uranium, and plutonium.
Elements across a series have the same number of attributes or characteristics.
