This fixed percent is called the definite proportion. Specifically, this phenomenon is states in the Law of Definite Proportions. According to John Dalton, all the individual elements making up the compound has a fixed ratio, whether in mass or in moles. For example, for any amount of H₂O, there will always be a fixed proportion of 2 H atoms: 1 O atom.

Mallebility is the property or ability of the metal to be hammered or pressed into shape without breaking or cracking.
Aluminium (Al) is metal, sulfur (s) and chlorine (Cl) are nonmetals.
Metals conduct electricity because of the metallic bond, sulfur and chlorine can not conduct electricity because they are nonpolar compounds.
Metallic bond is formed between electrons and positively charged metal ions
