What is an electric field and how does it interact with charged particles

electric field is a space surrounding a charged particle, where the particle exerts electric force

Explanation:

so when charged particles are close enough, they exert force on each other,their electric field interact.particles with opposite charges attracts while particles with like charges repel each other

the seeing the electronic configuration we can say that the element is fluorine.

fluorine is the most electronegative element in the periodic table.

but by only seeing the configuration we cannot say about its reactivity because we don't know if its configuration after excitation or by addition of electrons.

but if not then, it is the lightest halogen and exists as a highly toxic pale yellow diatomic gas at standard conditions. as the most electronegative element, it is extremely reactive: almost all other elements, including some noble gases, form compounds with fluorine.
