ASAP: The main difference between the gravitational force and electrical force is that 1. Gravitational force can only push
2. Gravitational force can pull and push
3. Electrical force can only pull
4. Electrical force can pull and push

it is a solid

explanation:

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.
