There has been no increase in the number of elements, it's just that people discovered ones that were unknown.
The only exception is the use of nuclear reactions (in accelerators, reactors, and bombs) to create technetium, promethium, and the transuranics. But many of these except for extreme transuranics already existed on earth but at such small trace levels they were unknown until long after they had been artificially made and measured.

What has caused the increase in the number of parathyroidectomy procedures?
The number of parathyroidectomy procedures has risen due to routine measurement of calcium in the blood.
What happens to the number of atoms in 1mol of each elements in the periodic table increase?
One mole of any element will have Avogadro number (6.023 x 1023) of atoms And this number remains the same for all elements.
How do elements in a period behave?
Elements in a period share the same number of electron shells, leading to similar chemical behaviors. As you move across a period from left to right, the atomic number and number of protons increase, leading to a gradual increase in electronegativity, ionization energy, and atomic size. Elements at the beginning of a period tend to be metals, while those at the end are nonmetals.
Why does the size of the elements increase down a group?
The atomic numbers of the elements down a group increase. this means, more electrons. More electrons mean more shells. More shells mean larger radius. Larger radius is nothing but larger size. Thus, the number of electrons or shells is the reason why the size of the atom of elements increase down the group.
How are elements arranged on the periodic table in order of electrons?
The number of electrons in the atom increase from left to right and then from top to bottom.

they do becaused they want to do it
Why do elements increase in size as you move down the periodic table?
Down the group, atomic radius increases. This is due to increase in number of shells.
