5f− inner transition series of elements are placed separately at the bottom of the periodic table. Reason: (i) This prevents the undue expansion of the periodic table i.e., maintains its structure. (ii) This preserves the principle of classification by keeping elements with similar properties in a single column.
<h3>What is the difference between transition and inner transition elements?</h3>
The main difference between transition metals and inner transition metals is that transition metal atoms have their valence electrons in the outermost d orbital whereas inner transition metal atoms have their valence electrons in the f orbital of the inner penultimate electron shell.
<h3>How many inner transition elements are there?</h3>
Total number of inner transition elements in periodic table is 28, 14 each in lanthanoid and actinioid series.

Based on the observations from, the substance that water is more attracted to are polar substances.
<h3>
What is the Polarity of water?</h3>
Water is a compound made up of 2 atoms of hydrogen and 1 atom of oxygen.
Water molecule is polar due to the unequal sharing of electrons between the atoms and the unsymmetrical shape of the molecule.
Since water molecules are polar, they are more attracted to molecules that are also polar.
Thus, based on the observations from, the substance that water is more attracted to are polar substances.

This demonstration is most likely trying to show you potential energy. The rock is heavier than the pebble and will therefore displace more sand upon impact showing that the rock stores more potential energy than the pebble does when they are elevated to the same height (in this case the height is the height of the table).
This makes sense since potential energy is equal to mass times the acceleration due to gravity times height (PE=mgh) and the only thing that is changing is the mass of the object being suspended which means that the heavier object (the rock) will have more potential energy.
I hope this helps. Let me know if anything is unclear.
