Poo. That is the answer. Go to an online tutor. I sugest pootutor.com. Go there to get your freking answer.
Flourine is not a Rare Earth Metal, but rather a Halogen, which is the second column from the right of the periodic table. Halogens react violently with Alkali Metals when heated and form stable compounds, usually salt like. Examples: Lithium + Flourine = Lithium Flouride Sodium + Chlorine = Sodium Chloride (Table salt)
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.
All alkali earth metals have two valence electrons and they all form ions in +II oxidation state.
All atoms want to do is make their valence shell full. In alkali metals they have all of their shells completely full except one valence electron. The alkali metals REALLY want to get rid of that electron, so they will react with many elements/compounds to get rid of that electron. In alkaline earth metals they have all of their shells completely full except for two valence electrons. They also want to get rid of those electrons but the alkaline earth metals are not as desperate to do so as the alkali earth metals which make the alkaline much less reactive than the alkali metals.
Yes, they do. Actually, they react violently when heated and in the presence of oxygen.
Alkaline earth metal
It is in alkaline group.Not in alkaline earth group.It is in alkaline group because, Hydrogen has maximum oxidation number of +1.It react with Halogens.Displaced by other alkaline metals.
prety sure that only Potassium (K) and Sodium (Na) can react with calcium. check the reactivity series for more info.
Water
Radium is a solid, radioactive, alkaline earth metal.
Aluminum can not be dissolved in water, because it is a metal from group 13. Only some of the earth alkaline metals and all of the alkaline metals dissolve (and react!) with water.
Yes, they do.
Yes, alkaline earth metals react with water forming their hydroxides.
Sr - strontium, is a highly reactive alkaline earth. It can react with moisture on the skin and other body parts to produce a very strong alkaline substance which will burn the skin. It is more reactive than calcium metal. It is also classed as a heavy metal.
Alkali metals are more reactive than alkaline earth metals.
No, they generally do, even at room temperature.
