Hydrogen is the "lightest" element.
The first level ionization energy oif aluminium is 577,5 kJ/mol.All alkali metals have lower values for the ionization energy.
Hydrogen is the first element because it has the simplest atomic structure with just one proton in its nucleus. This makes it have the smallest atomic number, which determines the element's position in the periodic table.
It is an element. Elements are composed of atoms, and atoms of elements combine chemically to form compounds.
This chemical element is dysprosium (Dy).
"He" is an element. It is the chemical symbol for helium, which is a noble gas and an element on the periodic table.
Li is an element. It is in the 1st group. It is an alkaline metal element.
The element Europium was named after the continent of Europe, the 1st largest continent in terms of land area.
It stands for Hydro fluoride acid.Only 1st letter is capital in a symbol of an element.
An interesting fact about hydrogen is that it is the oldest ,1st,and the lightest element of all.
CARBON
BERYLLIUM :)

A rule to get (calculate) a number from another number. ans.A function is a relation in which each element of the 1st set,it corresponds to one and only one element in the 2nd set.
Hydrogen is the element which is not alkaline metal but in the top of the periodic table. It is depicted in the 1st group because it has 1 valence electron. It is a non metal.
Potassium is the most reactive. It is in the 1st group. It is an alkaline metal.
hydrogen is an element of the periodic table and has the symbol H. hydrogen has 1 electron and is 1st on the periodic table.
No, silicon is the second most abundant. Oxygen takes 1st place.
