What is the ninth element on the periodic table of elements?
The ninth element on the periodic table of elements is fluorine (F). It is a highly reactive, pale yellow gas at room temperature. Fluorine is commonly used in toothpaste and water fluoridation to promote dental health.
Who is the scientist involved in the periodic table?
Dmitri Mendeleiev. The periodic table was in fact first known as the Mendeleiev table. I was not complete at the time of his death, but he predicted the existence of several elements not yet discovered.
What was the ninth country discovered?

How many electrons does ninth shell hold?
The ninth shell can hold a maximum of 162 electrons. This is determined by the formula 2n^2, where n represents the shell number. So for the ninth shell (n=9), the maximum number of electrons it can hold is 2(9)^2 = 162 electrons.

What are the empty spaces in the periodic table meant for?
It was recognized by the inventor of the Periodic table that these empty spaces are for elements/isotopes that would be discovered someday. Dmitri Mendeleev is generally credited with the publication, in 1869, of the first widely recognized periodic table. He developed his table to illustrate periodic trends in the properties of the then-known elements. Mendeleev also predicted some properties of then-unknown elements that would be expected to fill gaps in this table.
Is manganese a representative element?
Manganese is not a rare earth element. The rare earths range from Lanthanum (atomic number 57) to Hafnium (70) and Actinium (89) to Rutherfordium (102). Manganese is atomic number 25. Looking at the periodic table, you will see two rows at the bottom named Lanthanoids and Actinoids - those are the rare earths.
