Question

Define electropositivity. Which is the most electropositive element in the periodic table?

Answer 1

Electropositivity:

• The tendency of an atom to donate an electron and form a positively charged cation is called electropositivity.

Electropositive elements in the periodic table:

• In the periodic table, electropositive increases down the group and decreases across the period.
• Elements in group 1 are the most electropositive elements because they can easily lose an electron.
• Cesium $\left(\mathrm{Cs}\right)$ is the most electropositive element in the periodic table because it can easily lose its outermost electrons due to its large size and low ionization energy.
