Which statement best describes the formation of a solution?
A large amount of solute is dissolved in a smaller amount of solvent.
A small amount of solute is dissolved in a larger amount of solvent.
A small amount of solvent is dissolved in a larger amount of solute.
A large amount of solvent is dissolved in a larger amount of solute.

A small amount of solute dissolved in a larger amount of solvent.

Take this analogy to help you understand, if you were to put a teaspoon of sugar in a liter of water it would dissolve, but if you put a sack of sugar in it it would not dissolve! The solute is what is being dissolved and the solvent is what dissolves the solute, so that eliminates some of the options.

answerleaving cheese out to get moldy;

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.
