Question

What is the atomic number for the tin?

Answer 1

Hint: The chemical element tin is represented by the symbol $Sn$. The element got its symbol from the latin word stannum. It belongs to the group $14$of the modern periodic table. It is silver in color and has a yellow hue.

Complete answer:
The atomic number of $Sn$ is $50$. The metal is soft, malleable and also ductile. When a bar of $Sn$ is bent, a crackling sound is produced. This sound is called “tin cry”. This metal can resist corrosion from ${H_2}O$ but it is corroded by alkalis and acids. It can be polished and also used to coat other metals as protection. It forms a protective oxide layer which stops the metal from further oxidation. It is also used as a catalyst in some chemical reactions to speed up the chemical reaction. It does not occur as a native element but it is extracted from different ores. The important commercial source of this metal is $Sn{O_2}$ which is known as cassiterite. This element is used in alloys with lead as solder. $Sn$ with $Pb$ forms an eutectic mixture at the weight proportion of $61.9\% $ $Sn$ and $38.1\% $ $Pb$.

Note:
$Sn$ bonds to iron readily and is used to coat steel, lead and zinc in order to prevent corrosion. Steel containers plated with $Sn$ are used to preserve food which makes metallic tin very essential in everyday life. Cooking vessels made up of copper are lined with thin plating of tin because the combination of copper with acidic foods is toxic.
