What is electropositive element?
Electropositive elements – electropositive is those elements or groups that give up electrons such as metals and acidic hydrogen.
Electropositivity – The main function of electropositivity is to the ability of an atom to donate electrons and form positively charged cations. this is called electropositive elements.
According to periodic table, if down the group electropositive increases. Generally, alkali metals are most electropositive elements. and The Cesium is best example of most electropositive atoms in periodic table. It is also a stable elements.
Highest electropositive element
Electropositive are define as the ability of an atoms to donate electrons properly and it gives positively charged and cations.
if we are taking about most electropositive elements, You know, among all the elements of the periodic table, alkali metals are the most electropositive elements in periodic table. the highest electropositive elements are,
(a) Cesium
(b) Rubidium
(c) Potassium
(d) Sodium
(e) Lithium
Highest to lowest electropositive element
Caesium and francium are the highest electropositive elements in entire periodic table. Whereas, fluorine, chlorine, and oxygen are the most electropositive elements in periodic table.
Lowest electropositive element
Among all the alkaline metals, Lithium is the least electropositive elements.
Electropositive character
Electropositive character down the group, in a group,
From top to bottom in periodic table – if you see carefully in the entire periodic table from top to bottom, the atomic size increases.
As the atomic size increases, the nuclear attraction on the valence shells decreases.
Therefor, the ability to donate due to this tendency, electrons increases.
Which alkali has most electropositive character – Cesium is known to be the most electropositive stable element. Among all the elements of the periodic table, alkali metals are considered to be the most electropositive.
Cesium is an alkali metals and it is know as most electropositive stable element.
The basic decreasing order of electropositive elements is?
The basic decreasing order of electropositive charcter is,
Fe, Rb, Br, Te, F, Ca
What is the diffrence between electropositive vs electronegative?
The basic or actually difference between electropositive and electronegative is this that,
(1) The term electropositive refers to the ability to lose electrons as a result, it forming cations, whereas electronegative refers to the ability to gain electrons as a result, it forming anions.
(2) The most electropositive element is Francium whereas the most electronegative element is Fluorine.
Question And Answer
1 What are the 5 most electropositive element?
Yes, it is absolutely true, there are 5 most important electropositive elements are,
(a) Cesium
(b) Rubidium
(C) Potassium
(d) Sodium
(e) Lithium
2. What is the increasing order of electropositive?
The increasing Order of electropositive elements are,
Li < Na < k < Rb < Cs
3. Which alkali metals has most electropositive element?
On moving down the group, in a group, according to the moving down the group, the nuclear charge on the outermost electrons decreases.
Ba can lose the electrons, and it is known as a most electropositive elements.
Yes, Ba is most electropositive elements among the alkaline earth metals.
4. Why barium is most electropositive elements in group 2?
Yes, barium is most electropositive elements because, barium has the largest size due to which it can lose the outermost electrons from the shell. but whereas, Lithium is the least electropositive elements.
5. Why alkali metals are strong electropositive in nature?
Yes, alkali metals are strong electropositive in nature because of low ionization energy and their atom readily loss the valence electrons.
