A machine delivered 1000 protons/ hour ( this is frequency). What is the wave length and Energy. If the same machine was used to deliver a dose to a person’s elbow of mass 50.5 grams. What is the Dose in RAD and Dose in Gray.

listen, you cant how young you were.

"you didn't chose the stud life. the stud life chose you."

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.
