Igneous rocks with large crystals are because they cool and the surface.

intrusive, quickly, above

extrusive, quickly, below

extrusive, slowly, above

intrusive, slowly, below

Intrusive, slowly, below

Explanation:

There are three types of rocks- Sedimentary,Metamorphic and Igneous. Igneous rocks are formed when the molten(after melting by various processes) start getting crystallised below the surface.

.The molten rock materials consists of the magma and Lava. Melting can be caused by either increase in temperature or any other reason.

Intrusive ones solidify below Earth's surface and they start to cool slowly . Due to this reason we can see large crystals unlike other types of rocks. They are found on the crust of Earth.

Intrusive rocks are most common and constitute most of the igneous rocks.

the electronic configuration of an atom with eight electrons is 1s²2s²2p⁴. the orbital diagrams are shown in the figure.

as per the hunds rule:

1. electrons tend to avoid being in the same orbital as per as practicable.

2. electrons in different orbitals of the same energy will have their spin parallel.

this can be illustrated from the multiplicity of the orbitals of the atom. as there are four electrons in the p orbital and p orbital has 3 sub-shells. the electrons can be fed in different ways as shown in the figure but the correct orbital diagram will be as per the hunds rule.
