Na is +1 oxidation state. In the same order K is +1 and Ca is +2. The CS is +3 state. So Cs is most electropositive elements.

What is 'cs'?

Hut said: (May 1, 2012)  
cs is cesium.

Mudasir said: (Jun 18, 2012)  
As we move down the group the electro-positive character increases due to increase in size as a result the loss of electron become easy due to less nuclear influence.

What is electropositive?

Kanchan said: (Dec 26, 2013)  
Tending to release electrons and form positive ions or polarized bonds.

What is the chemical formula of chloroform?

Somini said: (Sep 9, 2014)  
Chloroform is CHCl3.

What is chemical bond?

Annie said: (Oct 17, 2014)  
Cs is the most electropositive.

Eswari said: (Nov 17, 2014)  
From top to bottom in periodic table atomic size is increases so electropositiveness also increases.

Asdf said: (Apr 2, 2015)  
Cs is most have ionic charge.

As we move down the group the electro-positive character increases due to increase in size as a result the loss of electron become easy due to less nuclear influence. In group 1A Francium is more electropositive than Cesium but, not stable as it is highly radioactive (maximum half-life of only 22 minutes). So cesium the most electropositive elements.

Vivek said: (Jan 22, 2016)  
Being at the bottom of periodic table its atomic size increases as a result nuclear pull between protons and neutrons become less, thus, electrons on the outer most shell can easily be transferred and become electropositive.

Gaurav said: (May 5, 2016)  
Cs - Caesium with atomic number 55.

Caesium is the most electropositive and the least electronegative element.

@Usama Khan.

A chemical bond is an attraction between the atoms that enables the formation of chemical compounds.

Darshan said: (Jun 18, 2016)  
What is meant by an ionic bond?

Sonal said: (Jun 28, 2016)  
@Darshan

An Ionic bond is formed when atom becomes ions by gaining or losing electrons.

Yusuf said: (Jul 21, 2016)  
Since the element is in the same group and electropositive increase down the group due to this Caesium which is the most electropositive.

Chandiran said: (Dec 16, 2016)  
Yes, agree @Yusuf.

Oladejo said: (Apr 28, 2017)  
Caesium belongs to which group on the periodic table and is it amount first-forty element?

Sagar said: (Nov 12, 2017)  
Caesium is the most electropositive element and fluorine is the most electro negative one they together form Caesium fluoride which is the most ionic compound.

Dalpat Ram said: (Dec 13, 2018)  
Cs is the most electroposotive element.

Mahwish said: (Oct 31, 2020)  
Increased size of Cs makes it more electro positive.
