Which statement best describes a model using a balloon to show that matter is made up of particles too small to be seen without magnification? It becomes colder as the air particles leave the balloon.
It becomes heavier as the air particles leave the balloon.
It becomes larger as the air particles leave the balloon.
It becomes smaller as the air particles leave the balloon.

answer7,570,82356 cubic centimeters;

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.
