Answer:
Native Elements; Metallic Elements
Explanation:
It means that 22.5×10^5 J of heat is required to change 1 kg of water into steam.
Latent heat of vaporization is amount of energy required to change 1 gram (in this example 1 kilogram) of material from the liquid to the gaseous state at its boiling point.
Boiling point of the water is 100°C.
Joule (J) is the standard unit for energy (in this example heat).
Evaporization is phase change process in which the water changes from a liquid to a gas (water vapor). Fore example, solar radiation can be the source of energy for evaporation.

Answer:
6 electrons
Explanation:
The principal quantum number n; describes the energy level and here, it is 2.
The azimuthal or secondary quantum number l is given as 1, we are describing the p-orbital
The magnetic quantum number is -1, and we have 3 sub-orbitals here:
It is a 2p-suborbital
So; in each sub orbital we have 2 electrons
The number of electrons that can be described here = 2 x 3 = 6 electrons.
