8,7x10⁻⁵ - 2,4x10⁻⁵ me pueden decir la respuesta de este ejercicio de notación cientifica lo necesito dentro de tres minutos porfa estare muy agradecida si me ayudan arigato

colorless gas, exhibiting a blue glow when placed in an electric field

b) solid

its a type of rock

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.
