The metalloids and the difference between the positive ion and the negative ion

The metalloids

The metalloids are semi-metallic elements which have the properties of both the metals and the nonmetals , It is difficult to know the metalloids from their outermost electrons due to the difference of the numbers of the electrons in their valencies shells .

The positive ion

The positive ion ( the cation ) is the atom of a metallic element that loses one electron or more during the chemical reactions , The positive ion carries positive charges equal to the number of the lost electrons .

The positive ion

The positive ion protons is more than that of its electrons

The number of the protons of the  positive ion is more than that of its electrons  , The electronic structure of the positive ion is similar to that of the nearest preceding inert gas .

The number of the energy levels in the  positive ion is less than the number of the energy levels in its atom .

The negative ion

The negative ion ( the anion ) is an atom of a nonmetallic element that gains one electron or more during the chemical reactions , The number of the electrons of the  negative ion is more than that of its protons .

The negative ion

The number of the energy levels in the negative ion is equal to the number of the energy levels in its atom .

The negative ion carries the negative charges equal to the number of the gained electrons .

You notice  that the number of the energy levels in the negative ion is equal to the number of the energy levels in its atom .

The electronic structure of the negative ion is similar to that of the nearest inert gas that follows .
