Calcium, Iron, Magnesium, Potassium, Sodium (but sodium in most cases be in the form as an Ion),
Transition metals.
The Alkali Metals are the first column of the periodic table, except for Hydrogen.
After atomic numbers Henry Moseley supported the arrangement of periodic table of Mendeleev after atomic numbers and properties by a strong physical conception: study of the lines of X-ray spectra of chemical elements. It is a true relation between atomic numbers of elements and the wavelenghts of the characteristic X-ray lines.
I am thinking either Dimitri Mendeleev or Henry Mosely
It is named The PERIODIC TABLE. The periods being the horizontal rows The groups being the vertical columns.
Transition metals.
No - Ba is from the periodic table though.
Aluminum contains 13 protons. It practically says so on the periodic tabe of elements because it's #13
The Alkali Metals are the first column of the periodic table, except for Hydrogen.
Atomic number A.K.A.: the number of protons in the nucleus of an atom of each element.

Uranium starts with letter U. So, its symbol is U.

118 elements are in the periodic table of elements; some of them are still unnamed (January 2013).
