What else can I help you with?
Which are products of the alkaline and earth alkaline metals combustion?
Alkaline metals and alkaline earth metals form their oxides when burnt. These oxides are base.
Which is more metallic alkaline metals or alkaline earth metals?
alkali metals
Is alkaline earth metal in the group of metals nonmetals metalloids or diatomic molecule?
The alkaline earth metals are metals!
Elements in group 2 are called?
Group 2 elements in the periodic table are the alkaline earth metals.
What metals softer and more reactive than other metals?
Potassium, sodium, and lithium are softer and more reactive than other metals. They are typically stored in oil or kerosene to prevent them from reacting with moisture in the air.
How many Alkaline and Alkali Metals are there?
Six alkali metals and six alkaline earths.
What are the key differences between alkaline earth metals and alkali metals?
Alkaline earth metals have two valence electrons, while alkali metals have one valence electron. Alkaline earth metals are harder and have higher melting points compared to alkali metals. Additionally, alkaline earth metals are less reactive than alkali metals.
Are alkali and alkaline earth metals are not reactive?
No. The alkali and alkaline earth metals are very reactive.
Which alkaline earth metals are radioactive?
Radium is the radioactive metal among alkaline earth metals.
Are metals alkaline?
Yes When metals react with water they produce a metal hydroxide, this contains an OH- ion (which accepts protons and is therefore alkaline) This makes all metals alkaline.
Are all alkaline earth metals metals?
no
What are general properties of alkaline metals?
Chemically they react with water to form alkaline hydroxides, a more vigorous reaction is produced by the larger alkaline metals than the smaller ones. Alkaline metals react with the halogens to form ionic salts, because they are so reactive they are rarely found in nature and have to be stored in mineral oil for use in labs In terms of physical properties they are soft, with low melting and boiling points and quite shinny.
