Altitude is height above sea level. The density of air decreases with height. There are two reasons, at higher altitudes there is less air pushing down from above,and gravity is weaker farther from earths center.

Answer:

The events in the rock cycle can be divided into categories:

a) Surface Events

These are the changes that occur on the surface of the earth. This includes weathering and erosion

Igneous Rocks

b) Subsurface Events

These are the changes in the cycle that occur in the inner surface of our planet. This is under the surface of Earth. This includes process like plate tectonics and mountain building.

(a) What is the maximum number of unpaired electrons in a lanthanide ion?
PtichkaEL [24]

Gd^{3+}  is the maximum number of unpaired electrons in a lanthanide ion.

<h3>What is meant by unpaired electrons?</h3>

Valence electrons are merely those that are in an atom's outermost shell, whereas unpaired electrons are electrons in an orbital that are alone. For instance, the electrical configuration of an atom is 1s2,2s2,2p6,3s1. An electron that is not paired has a magnetic dipole moment, however an electron pair does not since the two electrons' magnetic dipole fields cancel out because they have different spins. As a result, an atom with unpaired electrons behaves like a magnetic dipole and engages in magnetic field interaction.

A valence electron pair that does not share or form a bond with another atom is known as a lone pair. Lone pairs are a subset of the valence electrons in a molecule and are located at the outermost electron shell of an atom. The electrons that are not paired are known as unpaired electrons.

Hence Gd^{3+} is the maximum number of unpaired electrons in a lanthanide ion.
