It refers to the ability -or not- of a chemical substance to be able to dissolve in Water: in a word - Solubility.
"To use Lewis theory to determine the formula of an ionic compound, determine the number of valence electrons lost by the metal to form an octet, and the number of electrons gained by the nonmetal to form an octet." Refer the link below for further reading.
An electron in the outermost energy level of an atom is called a valence electron.(We refer here to the outermost occupied levels of an atom. There are, of course, many other higher energy levels normally available that are not occupied.)These electrons determine the chemical reactivity of the atom.the valence electrons
Properties of a substance refer to its characteristics, both physical and chemical. By characteristics we refer to its combination with other elements and what new substance is formed with this mixture. Properties also refer to density, temperature, odour, taste (when possible to check it out) Sincerely confessing I do not understand anything about properties in science. Experts, please, help me. Thanks.
OC can refer to a great number of places, people and organisations, as well as other jargon or terminology in other settings.

Minerals refer to the solid inorganic substances that occur naturally.
Zinc and Zircon. Refer to link below for other minerals starting with z.
Minerals refer to substances that are naturally formed in the Earth. Examples of minerals that make up the Earth's crust are gold, diamond and quartz.

The term is not applicable here. The terms fracture and cleavage refer to the manner in which minerals break. Gneiss is not a mineral, it is a rock composed of multiple minerals.
The ledger
Rock-forming minerals are the 20 most common minerals on Earth. However, 10 minerals actually make up 90 percent of the Earth's crust. We refer to these 10 minerals as "grains".
Desalination, desalinization, or desalinisation refers to any of several processes that remove excess salt and other minerals from water. More generally, desalination may also refer to the removal of salts and minerals, as in soil desalination.
When the dog wants to go out, she will scratch at the door. Did you scratch your arm climbing out of the tree? Please don't scratch your mosquito bites! Could you scratch my back?
Minerals is a geological term for solids with particular structures. See related link. Oil and natural gas are frequently listed as minerals by various organizations in discussing a country's "mineral wealth." Oil and gas are not minerals by the definition given on the related link, however they share one quality with minerals - they were formed by natural mechanical and chemical processes in the earth. Coal is a more complex issue because there are many types of coal, some types qualify as minerals. The terms graphite, anthracite and lignite refer to minerals. If I don't know the type of coal, I can refer to coal as a rock. See related links.
External forces may refer to places.
