You are about to undertake an experiment to determine the atomic mass of an element that you recently discovered and named Beanium. Research has verified the existence of 3 isotopes of this new element, which are called: LIMA-49, KIDNEY-51, and PINTO-54. Required:
Use the sample provided to determine the % occurrence of each isotope and then calculate the atomic mass of your element.

explanation:

i think option no d is the correct answer

it is the most commonly accepted one

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.
