The answer lies in the concept of quantum mechanics. Every single electron of an atom has its own unique set of quantum numbers. It is stated in the Pauli Exclusion principle that no two electrons would have the same quantum numbers. That is why each electron occupies a specific orbital. In addition to the Pauli Exclusion Principle, the other laws and principles that help set the quantum numbers are the Aufbau Principle and the Hund's rule.

Answer:
Sublimation and the water cycle:
Sublimation is the conversion between the solid and the gaseous phases of matter, with no intermediate liquid stage. ... "Dry ice" is actually solid, frozen carbon dioxide, which happens to sublimate, or turn to gas, at a chilly -78.5 °C (-109.3°F).

Answer:
3. Granite and Gneiss.
Gneiss is a coarse to medium grained banded metamorphic rock formed from igneous or sedimentary rocks during regional metamorphism. Banded gneisses called migmatites are composed of alternating light colored layers of granite or quartz feldspar and dark layers rich in biotite.
Granite is a purely natural stone that comes directly from stone quarries and is then cut into thin slabs, polished, and fabricated into countertops. So-called quartz countertops are engineered stone products that may contain a large percentage of natural quartz but may also include other minerals.
