Within any group of elements (columns), the metallic character increases from top to bottom (the electronegativity and ionization energy values generally decrease as we move down a group). There are deposits of billions of tonnes of potassium chloride throughout the world. The metals are coloured blue in the Periodic Table above. Elements that tend to gain electrons to form anions during chemical reactions are called non-metals. f. Which element has the smallest ionization energy? Elements are further classified into metals, non-metals, and metalloids. Compounds composed entirely of nonmetals are molecular substances (not ionic). These are electronegative elements with high ionization energies. The number of atoms of the element per 1 million atoms of the Earths crust. If you are in any doubt, please ask.
They also have a larger number of valence electrons, and are already
Uncombined elements have an oxidation state of 0. So, we conclude that sodium and potassium are metals.

Different metals can be combined very easily to make
Ionic bonds form when there is a transfer of electrons . Metal oxides exhibit their basic chemical nature by reacting with acids to form salts and water: \[MgO_{(s)} + HCl_{(aq)} \rightarrow MgCl_{2(aq)} + H_2O_{(l)} \label{1.6}\], \[NiO_{(s)} + H_2SO_{4(aq)} \rightarrow NiSO_{4(aq)} + H_2O_{(l)} \label{1.7}\].
