what happens to electropositivity as we move from lithium to potassium
Answers
Explanation:
Explaining reactivity
The Group 1 elements have similar properties because of the electronic structure of their atoms - they all have one electron in their outer shell.
Table showing the electronic structure and atomic diagram for group 1 elements lithium, sodium and potassium.
Explaining trends
In a reaction, an atom of a Group 1 element will form an ion with a single positive charge. For example, for sodium forming a sodium ion:
Na → Na+ + e–
A change like this, where an electron is lost, is an example of oxidation.
The ions formed have a stable electronic structure, like a noble gas from Group 0.

The reactivity of Group 1 elements increases as you go down the group because:
the atoms get larger as you go down the group
the outer electron gets further from the nucleus as you go down the group
the attraction between the nucleus and outer electron gets weaker as you go down the group - so the electron is more easily lostExplaining reactivity

Answer:
HERE IS UR ANSWER MATE:
down the group ,
electro positivity
increases....
Explanation:
due to decrease in nuclear charge down the group
hence ,
here from Li to K , EP increases ..
