6. How are alkali metals different from noble gases? Ans.Alkali metals have a single electron on their outer shell, while all the noble gases (the Group 8 elements in the periodic table including helium, neon, argon) have a full valence band with no unpaired electron to cause a reaction ...

Definition: What are Alkaline Earth Metals Alkaline earth metals are a group of highly reactive elements placed right next to the alkali metal group. Although all the alkaline metals are found in nature, their high reactivity prevents them from occuring freely or in their pure form[1, 2]. ...

Definition of Alkali Metals Alkali metals form a part of the leftmost group, i.e. group 1 of the modern periodic table. It contains six elements, which are collaboratively called the Lithium family. These metals are highly reactive metals of the periodic table due to the presence of one elec...
Cation vs anion periodic table It can be possible to predict whether an atom will form a cation or an anion based on its position on the periodic table. Halogens always form anions, alkali metals and alkaline earth metals always form cations. Most other metals form cations (e.g. i...
- The s-block elements, which are the elements in the first two rows of the periodic table. These elements include the alkali metals (such as lithium and sodium) and the alkaline earth metals (such as beryllium and magnesium). These elements have a valence electron in the s-orbital. ...

In chemistry, s-block refers to a group of elements on the periodic table that all have their valence electrons occupying the same electron orbital, the s-orbital. S-block elements include hydrogen and helium, and alkali metals and alkaline earth metals. Which elements belongs to s-block? The...
In fact there is an intermediate range of elements, the metalloids, which share the properties of both metals and non-metals. However, we can regard the elements which can readily lose an electron, by ionization or bond formation, as strongly metallic in character (e.g. alkali metals). ...
