Look at a Periodic Table. Only elements are included on the period table.
You will find that aluminium, silicon and tin are all on the periodic table.
Aluminium (Al) is atomic number 13.
Silicon (Si) is atomic number 14.
Tin (Sn) is atomic number 50.
The elements of the mantle are silicon, oxygen, iron, and aluminium.
Sulfur.
Aluminium, Silicon, Zinc, Iron, and many more
Carbon, silicon, germanium, tin, lead.
the group 4A elements
The elements of the mantle are silicon, oxygen, iron, and aluminium.
Oxygen, Silicon, Aluminium, Iron, Calcium, Sodium, Potassium, Magnessium, Titanium, Phosphorus, Tin.
Examples are: iron, aluminium, tin, zinc, silicon, uranium, manganese, magnesium, chlorine, sulfur, etc.
Oxygen and silicon are two of the principle elements. See the related link.
Additions of silicon make *Aluminium and Tin/Copper (bronze) alloys stronger, stiffer, more resistant to wear.
Bronze: a copper-tin alloy, sometimes alloyed with phosphorous, aluminium, manganese, silicon, arsen or beryllium as minor constituents.
In the earth crust: silicon, aluminium, oxygen.
Sulfur.
Aluminium, Silicon, Zinc, Iron, and many more
germanium, tin, and lead
Carbon, silicon, germanium, tin, lead.
As far as I know: Silicon,Oxygen,Iron,Aluminium.
