What is a characteristic property of an Alkaline earth metal?
One characteristic property of alkaline earth metals is their tendency to form ionic compounds with a +2 oxidation state. This makes them readily react with nonmetals to form stable compounds. Additionally, alkaline earth metals have relatively low electron affinities, making them less reactive than alkali metals.
Do alkaline earth metals react with air?
Alkaline earth metals, such as magnesium and calcium, do react with air. When exposed to oxygen, they form oxides or hydroxides on their surface, which can give them a characteristic dull appearance. The reactivity increases as you move down the group from beryllium to radium.
What characteristic does the alkali metals alkaline earth metals and the halogens have in common?
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.
Elements in group 2 are called?
Group 2 elements in the periodic table are the alkaline earth metals.
Is Strontium Sr Alkali Alkaline-earth or transition?
Strontium (Sr) is classified as an alkaline earth metal. It belongs to group 2 of the periodic table, which includes elements that are commonly referred to as alkaline earth metals due to their similar chemical properties.
What are characteristic property of the alkaline earth metals?
they are harder than alkali metals

What is the characteristics of alkaline?
* alkaline metals contain the higher melting and also the boiling points. * These metals are present in the earths crust which does not have a basic form. * Alkaline earth metals are distributed in structure which is named as rock. * These metals have density which is low. * Alkaline earth metals have low electron affinity and as wells as low electronegativity. * One of the basic characteristic is, it contains two electrons in their outer shell.
What is the family name that calcium is in?
Group 2 (alkaline earth metals): lithium, sodium, potassium, caesium, rubidium, francium.

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.
Is aluminum an alkaline earth metal?
No, aluminum is not an alkaline earth metal. Aluminum is a post-transition metal, not an alkaline earth metal. Alkaline earth metals include elements like calcium, magnesium, and barium.
Is krypton a alkaline earth metal?
It is not an alkaline earth metal it is a noble gas
