Question

Identify the position of All and S in periodic table. And write formula between them.

Answer 1

✨POSITION OF ALUMINIUM✨

➡Aluminium is a chemical element with symbol ' Al ' and atomic number 13. It is a silvery-white, soft, nonmagnetic and ductile metal in the boron group.

➡Aluminum is the 13th element on the periodic table. It is located in period 3 and group 13.

✨POSITION OF SULPHUR✨

➡Sulphur is a nonmetallic solid with element symbol ' S 'and atomic number 16. Like the other nonmetals, it is found in the upper right side of the periodic table.

➡ Sulfur is the 16th element on the periodic table. It is located in period 3 and group 16. It is directly below oxygen (O) and between phosphorus (P) and chlorine (Cl).

✨FORMULA✨

➡Aluminum's outer shell has ' 3 ' valance electrons.

➡Sulphur's outer shell has ' 2 ' valance electrons.

➡So when they both combine, they form " Al2S3 "

➡They combine to form " Aluminium Sulphide "



Hope it helps!☺

Answer 2

Aluminium is located in period 3 and in group 13.

Al (2, 8, 3) has a valency of 3.

Sulphur lies in period 3, in group 16.

S ( 2, 8, 6) has a valency of -2.

Al. S

3. -2

Al2S3
