The atomic number for aluminium is 13.
Aluminium si most reactive because is vrey quick lead.
Added alloying (Cu, Mg, Mn, Zn, Si, Zr etc.) metals have the special role to improve mechanical properties of aluminium.
The answer depends on where the numbers are.
Al2O3, aluminium oxide. Remember the numbers must be subscripts.
All the numbers in the world are real. Therefor they are all real numbers.
In chemistry, hyphen notation is used to indicate the isotopes of an element by following the element's symbol with a hyphen and the mass number. For silicon (Si), the common isotopes are represented as Si-28, Si-29, and Si-30, where the numbers denote the mass numbers of the isotopes. This notation helps differentiate between the isotopes based on their neutron counts.
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.
Aluminium is actually an element, so the only element in aluminium is aluminium.
Aluminium. Aluminium. Aluminium.
Aluminium. Aluminium. Aluminium.
The LCM of the given three numbers is 60
1000 kg aluminium oxide contain 470,588 kg aluminium.
