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 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.
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.
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.
Which process in the water cycle is caused by an increase in temperature?
Evaporation is the process in the water cycle caused by an increase in temperature.
What caused the number of convicts laborers to increase?
Black codes
What happens to the reactivity of elements in group a as atomic number increase across a period?
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.

One mole of any element will have Avogadro number (6.023 x 1023) of atoms And this number remains the same for all elements.
What has caused the increase in the number of parathyroidectomy procedures?

What invention led to a huge increase in the number of slaves in the South?
The cotton gin led to a huge increase in the number of slaves in the South. This happened because the cotton gin caused more cotton to be produced.
What trend in atomic radius do you see as you go down a group on the periodic?
The atomic radius of elements increases as you go down a group. This increase in radius as you go down a period is primarily caused by the increasing principal quantum number of the outer electron shells.
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.
What caused the demand for financial information?
With the increase in the number of corporations, there also arose a demand for additional financial information
What caused an increase in the number in the northern English colonies?
