Respuesta :
The elements from the left side of the P.T are found as oxides and right side are found as sulfides.
Where are oxides found in periodic table ?
Metals towards the left side of the periodic table have lower ionization energies. Metals towards the left side of the periodic table have lower electro negativities they tend to give up electrons. The O2- ion is small cation closely which has high lattice energy for the oxides.
Therefore, the elements from the left side of the P.T are found as oxides.
Where are sulfides found in periodic table ?
Metals towards the right side of the periodic table have higher ionization energies. Metals towards the right side of the periodic table have higher electro negativities they tend to form covalent bonds which suits the larger, more polarizable (S2-) ion.
Therefore, the elements from right side of the P.T are found as sulfides.
Thus from the above conclusion we can say that The elements from the left side of the P.T are found as oxides and right side are found as sulfides.
