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 with other molecules[15]. ...
Location of the Alkali Metals on the Periodic Table The alkali metals are the elements located in Group IA of theperiodic table. The alkali metals are lithium, sodium, potassium, rubidium, cesium, and francium. Alkali Metal Properties The alkali metals exhibit many of the physical properties comm...
Hydrogen, with a solitary electron, is usually placed at the top of Group 1 of the periodic table, but it is not considered an alkali metal; rather it exists naturally as a diatomicgas. Removal of its single electron requires considerably more energy than removal of the outer electron for ...
alkali metals, metals found in Group 1 of the periodic table. Compared to other metals they are soft and have low melting points and densities. Alkali metals are powerful reducing agents and form univalent compounds. All react violently with water,
If not, then don't worry. Group 1 of the periodic table consists of alkali metals along with Hydrogen. There are six elements in the group. These are named Alkali Metals because they form strong bases on reactions with water. This article contains information about alkali metals,important prop...
Lithium (Li: atomic number 3), sodium (Na:11), and potassium (K:19) are very reactive, monovalent alkali metals that occupy the Group 1A position on the periodic table. These metals find extensive applications in many industries, both as pure metal as well as compounds. Application in comp...
The alkali metals are the elements that make up Group 1 of the periodic table: lithium, sodium, potassium, rubidium, cesium, and francium. These elements are all much too active to exist in nature in their native state. However, they do form a number of important compounds, such as table...

Alkali metals are metals that can be found in Group 1A (Column 1; aside from hydrogen) on the Periodic Table of the Elements. They make up many salts in the earth's crust and have found a myriad of uses in modern society. The natural abundance in order is sodium, potassium, rubidium,...
