What are alkaline earth metals?
They are a series of elements, or metals, on the Periodic Table of Elements. The alkaline earth metals are: beryllium, magnesium, calcium, strontium, barium, and radium (i.e, the ones with two electrons in their outer shell and common oxidation state +2, right next to the alkali metals with common oxidation state +1). They're all silvery-colored and soft, and they combine with water to form alkaline hydroxides, but not as readily as the alkali metals do.
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.
How is the fur coat of a bear related to homeostasis?
The fur coat of a bear helps to maintain a body temperature that is warmer than the surrounding environment; a characteristic common to mammals.

How did the alkaline earth metal get their name?
1. Their oxides are base (alkaline) forming with water.2. The high amounts of the most common elements in this group, Mg and Ca, are found in rocky earth crust and sediments. (Eg. slack lime Ca(OH)2, carbonate rocks, magnesite).Another explanation of 'earth' is this:3. These oxides melt at such high temperature that they remain solids ("earths") in fires (Eg. burned lime CaO).Added:The alkaline earth metals are a series of elements comprising Group 2 (IUPAC style) (Group IIA) of the Periodic Table:beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba) and radium (Ra).
What is the important characteristic do the alkali and alkaline earth metals have in common?
they all have at least one electron
What are the common properties of halogen?
highly reactive with alkali metals and alkaline earth metals
What are the names of some common alkalines?
Two most common alkaline earth metals are Beryllium and Magnesium, while the most common alkali hydroxide is sodium hydroxide.
What everyday substance is an alkali?
Bicarbonate of Soda commonly used for cooking (plus a range of other things) is a common everyday Alkaline.
What alkaline is in fertilizer?
No, not in general and I've never heard of it been used that way.
What alkali has a pH value between 11 and 14?
A solution with a pH value between 11 and 14 is highly alkaline. Common examples of alkalis that can have such pH values are sodium hydroxide (NaOH) and potassium hydroxide (KOH).

What is an element with a single electron in its highest energy level is probably what type of metal?
An element with two electrons in its highest energy level is probably an alkaline earth metal. More specifically, it is likely magnesium or calcium, as these are the most common alkaline earth metals.
What important characteristics do the alkali metals and earth metals have in common?
They all have at least one electron.
What is the Difference between a bases and alkali?
Alkali is a basic, ionic salt of an alkali metal or alkaline earth metal element. Alkalis are best known for being bases that dissolve in water. (Most common form is hydroxide.)A base is most commonly thought of as an aqueous substance that can accept H+ ions.A soluble base is also often referred to as an alkali if hydroxide ions (OH−) are involved."All alkali are bases but not all bases are alkali"

How do you classify a metal as alkali alkaline earth or transition metal?
I'm assuming you're thinking of metals like Stainless Steel, Iron, Copper Wiring. These are compound metals made up of several elements. They aren't Transition, Alkali, or Alkaline Earth, they're just metals. Alkali, Alkaline-Earth, and Transition metals are elements, like Sodium or Cobalt. Alkali metal: These are members of group 1 on the periodic table. They are bases (as opposed to acids) and are extremely reactive. They include Sodium and Potassium Alkaline-Earth metals: These are members of group 2 on the periodic table. The are related to the Alkali metals, but are less reactive. They are also alkalines and found in the earth, as the name suggests. Transition metals: These are the most common metals. They are groups 3-I believe 15. They tend to lack acidic or basic properties. They are also the best at carrying electric currents. Hope I helped!
