Answer:

AlP

Explanation:

A formula unit is essentially the lowest ratio in which the elements or ions combine to form an extended network of a compound. These are not discrete molecules but a network of ionic or covalent compounds.

In the given examples, AlP is a correct formula unit which is a combination of a metal (Al3+) and a non-metal (P3-).

In the remaining examples:

PbCl is incorrect as it exists as PbCl2

Li3Al is a combination of 2 metals

ClO can exist as independent/isolated molecules and not as a network

Answer:  AIP  

There are two types of substances mixture and pure substance. Mixture has NO chemical formula and a pure substance has a chemical formula. There are two types of pure substances, elements (mono atomic and molecular) and compounds ( covalent and ionic).  

Ionic compounds do not exist in independent molecular form. They form three dimensional crystal lattice, in which each ion is surrounded by oppositely charged ion.  so the ratio of ion is called the formula unit

The name is derived from the Latin word cirrus, meaning 'ringlet' or 'curling lock of hair'. Such a cloud can form at any altitude between 5,000 and 13,700 m above sea level.</em>

<u>stratus:</u><em> </em><em>Stratus clouds are low-level clouds characterized by horizontal layering with a uniform base, as opposed to convective or cumuliform clouds that are formed by rising thermals.</em>

<u>nimbus</u>: <em>Nimbostratus clouds are dark, grey, featureless layers of cloud, thick enough to block out the Sun and produce persistent rain. Height of base: 2,000 - 10,000 ft. Shape: Bands or areas of individual cells. Latin: nimbus - rainy cloud; stratus - flattened or spread out. Precipitation: Continuous rain or snow likely.</em>

grouped together as trade winds, easterlies,

and westerlies.
