they loose an electron to become stable hence are positively charged.They react with water to form stong bases
2 valence electrons (apex)
Alkaline Earth Metals
the groups of alkali metals, alkaline earth metals, transition metals, and other metal are all metals and some of the metalloids have metallic properties and the alkali, alkaline are on the left, transition metals are in the middle, other metals are located directly next to the transition metals and the metalloids are next to the other metals, and then you have halogens and Nobel gases, Lanthanides and Actinides which are all gases and rare earth.
their general properties is that they are all non metals
Group 2 elements in the periodic table are the alkaline earth metals.
The elements of the second group are called the Alkaline Earth metals.
The second group in the periodic table is called the alkaline earth metals. These elements include beryllium, magnesium, calcium, strontium, barium, and radium. They share similar chemical properties such as reactivity and the ability to form ionic compounds with other elements.
Beryllium magnesium strantium calcium barium radium
The alkali metals are generally more reactive than the alkaline earth metals. They form 1+ ions while the alkaline earth metals form 2+ ions. Alkali metal compounds tend to be more soluble in water than alkaline earth metals.
Two elements that are alkaline earth metals are calcium and magnesium.
Lutetium tends to form compounds with elements that have similar chemical properties, such as other lanthanides and some transition metals. It does not typically form stable compounds with alkali metals and alkaline earth metals, as they have very different chemical properties from lutetium.
they're metals, to be precise gr1 alkaline gr2 alkaline earth. Both have metallic properties: conduct heat and electricity; malleable/ductile etc. Gr1 metals are soft and very reactive.
