Natasha measures the masses of three objects and records her results in the table. Object MassSphereCube400 g378 g4129PyramidWhat should Natasha do next to determine the densities of the objects?She should measure the volume of each object. She should mea[ure the temperature of each object. She should measure the circumference of each objectO She should measure the surface area of each object.

the temperature of the gas, in k, not celsius.

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.
