A state function describes the equilibrium state of a system, thus also describing the type of system. ... Internal energy, enthalpy, and entropy are examples of state quantities because they quantitatively describe an equilibrium state of a thermodynamic system, regardless of how the system arrived in that state. Examples of state functions include density, internal energy, enthalpy, entropy.

Alkali metals are the first group in the periodic table. They are never found in nature uncombined because they are unstable and they react fast to other elements. They bond well with all elements except the noble gases.
ans no. 13
Halogens have the highest negative value of electron gain enthalpy. Here Cl and F both are halogens but electron gain enthalpy of Cl is more negative than F because of the very small size of F which causes interelectronic repulsion among its electrons. Cl has the most negative one. P has the least negative one due to the larger size.
