Alkali metals are present in group 1 of the Periodic Table except hydrogen which is a non-metal. these elements are:-
Hydrogen(H)
Lithium(Li)
sodium(Na)
potassium(K)
rubidium(Rb)
cesium(Cs)
francium(Fr)
the common group elements have same number of valence electron in outermost shell and exibits same kind of property
Lithium. It is salt (not to be confused with table salt). One use is to bind it with potassium to make lithium carbonate for people who need a mood stabilizer, i.e. Bipolar disorder patients.
The pure elements are very reactive and as such have limited uses. Their compounds however are important, common salt for instance!
The elements present in group 1 are:
H
Li
Na
K
Rb
Cs
Fr
The alkali metals are: Li, Na, K, Rb, Cs, Fr.
The elements in group 1/IA are the alkali metals.
That element would be in the Alkali Metals (group one)
Both statements are true:Every element in group I has one electron in its outer shell andEvery element in group II has two electrons in its outer shell
Two of them. A group 2 element has two valency electrons whereas those in group 17 have 7. The latter need one electron to make an ionic bond so two of them can react with a single group 2 element.
When the element moves from group 18 to group 1, it moves to a new period. Each period has a one more electron shell than the previous. The group 1 element has one more electron shell than the group 18 element; hence, it's atomic radius is greater.
It is hydrogen. This element is the only one in its group because it is extremely unique and shares none of the properties of other gases.
"Carbonate" is not an element or an element group; instead, it is a polyatomic anion and is one of a large group of oxyanions.
That element would be in the Alkali Metals (group one)
Group one elements are the most reactive with group 7 elements as it is the easiest way for the elements to complete their outer shell as the group one element gives its extra electron to the group 7 element and then the group 7 element has a full shell too.
Both statements are true:Every element in group I has one electron in its outer shell andEvery element in group II has two electrons in its outer shell
A Group 6A element gains two electrons A Group 2A element loses two electrons A Group 3A element loses three electrons A Group 3A element loses three electrons group 1a element loses one electron group 7a gains one electron
This element is francium.
Any element in group 1
It is about Cf element. it is in the !8th group.
Francium
You can have a Group with only one element: 0 if it an additive group or 1 if it is multiplicative.
Two of them. A group 2 element has two valency electrons whereas those in group 17 have 7. The latter need one electron to make an ionic bond so two of them can react with a single group 2 element.
When the element moves from group 18 to group 1, it moves to a new period. Each period has a one more electron shell than the previous. The group 1 element has one more electron shell than the group 18 element; hence, it's atomic radius is greater.
