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...
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, releasing hydrogen and forming hydroxides. They...
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...
The electropositive (alkali, alkaline-earth, and rare-earth) atoms have low ionization energies and form strongly polar adsorption bonds with substrates that consist of elements from other groups of the periodic table. A substantial part of the electron density of their valence shells is transferred...
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 react vigorouslyto water and air. These elements will dance around, sizzling due to the production of hydrogen gas, and often explode. They get more reactive the further down on the periodic table you go too, with cesium and francium being so reactive that they can burst into ...

Alkali metals are the six elements that comprise Group I in the Periodic Table: lithium (Li), sodium (Na), potassium (K), rubidium (Rb), cesium (Cs), and francium (Fr). Especially when dissolved in water, these elements form strong bases (alkalis) capable of reacting with and ...
Few alkali metals are softer than other metals in periodic table. From the list of Alkali metals, Francium & Cesium are the most reactive metals. Alkali metals tarnish (oxidation) rapidly in the air. Along with alkali metals, you can also view the metals in other categories like Toxic ...
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,...
