This is [noble gas] 2s2 to 7s2.
All alkali metals, alkaline earth metals, and halogens have a common valence electron configuration: alkali metals have 1 valence electron, alkaline earth metals have 2 valence electrons, and halogens have 7 valence electrons. This shared electron configuration influences their chemical properties, such as reactivity and bonding tendencies.
2 electrons in the outermost shell.
The oxidation number of alkaline earth metals is typically +2. This is because they have two valence electrons, which they tend to lose to achieve a stable electron configuration.
Alkaline metals and alkaline earth metals form their oxides when burnt. These oxides are base.
Group 2 elements in the periodic table are the alkaline earth metals.
ns^2
alkali metals
The alkaline earth metals are metals!
All alkaline earth metals loss two electrons.
No. The alkali and alkaline earth metals are very reactive.
Radium is the radioactive metal among alkaline earth metals.
The oxidation number of alkaline earth metals, such as beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), and barium (Ba), is typically +2. This is because they tend to lose two electrons to achieve a stable electron configuration.
