Why are the groups alkaline earth metals halogens called so?
They react with water like the alkaline metal but does not change or melt with fire.The alkaline part of the name comes from the fact that these metal form alkaline solutions, when they react with water. The earth part was added to differentiate these from the group one metals. Alchemists called them earth metals because they though that their oxides were new elements.In the middle age the oxides of these metals (metals which are not known in time) are called alkaline earths: alkalinebecause these oxides react with water forming an alkaline solution and earths because in the past non-metallic compounds were called earths.

Which term describes the point on the earth surface above the area where an earthquake originated?
The term that describes the point on the Earth's surface above the area where an earthquake originates is it's epicenter.
What is the term used for the graphic representation earthquake on paper?
Earth
How did alkaline earth metals get their names?
Alkaline earth metals were named "earth" to differentiate them from alkali metals, which were known to form alkaline solutions when reacting with water. The term "alkaline" was added to indicate they were compounds with a high pH.
Why are the elements in group 2 called alkaline earth metals?
Group 2 elements are called alkaline earth metals because they form alkaline solutions when they react with water. The term "earth" indicates that these elements were found in the earth's crust, while "alkaline" describes the basic nature of the compounds they form.
Why group 2A are called the alkali earth metals?
The name "Alkali" is given due to the alkaline nature of their oxides and hydroxides. The term "Alkali Earth Metals" is used as these metals are usually found as minerals in the Earth's crust.

What is the collective term for the elements on the left side of the periodic table?
The elements on the left (well, pretty much the whole table bar the far right side) are metals.
What term is used to describe naturally occurring compounds of metals?
Almost all inorganic compounds contain metals, depending upon the type of bonding. These are mainly of 2 types: salts and complexes. Mostly alkali and alkaline earth metals form salts while transition metals form complexes.
Why is group one on the periodic table called the alkai metals?
Litmus paper changes color in acidic (red) and basic (blue) solutions. Given that "alkaline" is a synonym for basic, the title for Group IIA metals would literally be The Basic Earth Metals. Furthermore, "earth" is used because of the elements natural occurrence in the planet. It can also be determined from a lab that after Calcium (Ca) turnings are placed into distilled water, litmus paper will turn blue signifying the previously acidic solution has become more basic; many metals in Group IIA are the same.
Is a base an alkaline?
"Base" is a more general term. For a base to be alkaline it has to be soluble in water and it has to be formed from an alkali metal or alkaline earth metal.
What term describes the reactive nonmetals that have seven valence electrons?
alkali earth metals
What is another term that can be used whenreferring to a basic solution?
An alternate term for a basic solution is alkaline solution.
Is corrosive a acid or alkaline?
Corrosive substances can be either acidic or alkaline. The term "corrosive" refers to the ability of a substance to cause damage or destruction to materials it comes into contact with, such as metals or living tissues. Examples of corrosive substances include strong acids like hydrochloric acid and strong alkaline substances like sodium hydroxide.
What are the names of the groups on the periodic table and why that names?
Group 1 is called the alkali metals as all the elements are metals and the metals react with water to form an alkaline solution. Group 2 elements are called alkali earth metals. Alkali as the oxides are alkaline when combinedwith water. Earth is an old term meaning nonmetallic substances that are insoluble in water and resistant to heating- as are group 2 oxides. (wikipedia) The transition metals (sometimes called groups 3-12) are ordinary metals. Transition refers to the change of the inner shell of electrons from full on one side to the next full number. Group 13 (starting with Boron) also called the earth metals (earth for the reason above) or triels as they have 3 electrons in the outer shell Group 14 sometimes called tetrels as they have 4 outer electrons Group 15 also called pnictogens Group 16- chalcogens literally copper-former associated wit forming many metal ores. Group 17- halogens- literally "come to be" as they are visilbe easily in compounds likesea salt Group 18- noble gases as they don't react at all with a few exceptions Lanthanides and Actinides are simply similar to Lanthanium and Actinium respectively and are sometimes called rare earth metals as they are particularly rare or difficult to extract and store, largely because they are radioactive.
