Which of the following elements has chemical properties similar to potassium? Calcium,arsenic,yrtrium,cesium, or cerium
Answers
The most common use for caesium compounds is as a drilling fluid. They are also used to make special optical glass, as a catalyst promoter, in vacuum tubes and in radiation monitoring equipment. One of its most important uses is in the 'caesium clock' (atomic clock).
Among all the elements of the periodic table, the alkali metals are considered to be the most electropositive. Caesium is known to be the most electropositive stable element. Though unstable, Francium is believed to be the most electropositive element in theory.
Cesium has chemical properties similar to potassium.
Explanation
As we all know potassium and cesium both are alkali metals and falls in a same group.
From that only we can say that they both have similar chemical properties.
They have similar chemical properties like high thermal and electrical conductivity,
They are lustrous, ductile, and malleable which are characteristic of almost all metals.
Each of them has only one electron in its outermost shell ,which is weakly bounded than inner orbital shells.
Similarly,
- They are very reactive.
- They can easily catch fire in an open air.
- They are soft.
- Low melting point.
- Gives vigorous reaction with water.
Hence Cesium is the correct answer
