The Alkali Metals are more like each other than the components in any of the other groups are to each other. For example, while moving down the table, all the discovered and recognized Alkali Metals show expanding nuclear radius, diminishing Electronegativity, expanding reactivity, and diminishing,...

Alkaline Earth Metals Uses FAQ Interesting Facts 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 occuri...
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 ...
Standard state: solid at 298 K Appearance: silvery white/grey Classification: Metallic Group in periodic table: 1 Group name: Alkali metal Period in periodic table: 2 Block in periodic table: s Shell structure: 2.1 CAS Registry: 7439-93-2Lithium...
Alkali and Alkalinse earth metals 2 Transition Metals More so than any of the other major groups of elements in the periodic table, the transition metals have shaped human history and have been the workhorses of industry. The discover...
"As I flipped through the pages of [my chemistry textbook] trying to decipher the meaning of the title, a flashback to Grade 10 suddenly reminded me of the Periodic Table. How we used to make numerous mnemonics to memorize the Alkali metals, Alkaline Earth metals, Halogens, Noble gases ...
J.W. Döbereinerin 1817 showed that the combining weight, meaningatomic weight, ofstrontiumlies midway between those ofcalciumandbarium, and some years later he showed that other such “triads” exist (chlorine,bromine, andiodine[halogens] andlithium,sodium, andpotassium[alkali metals]). J.-...
Thealkali metals, in Group 1 (Ia), can assume the noble-gas configuration by losing oneelectron, which is loosely held in the outermost (valence) shell, to another element with greaterelectron affinity, thus producing the stable singly charged positiveions. Similarly the alkaline-earth metals ...
The alkali metals, for instance, are in the first column or group of the table and tend to have one valence electron and so carry a charge of +1. This charge means they "react vigorously with water, and combine readily with nonmetals," chemist Anne Marie Helmenstine wrote on ThoughtCo....
