There are 7 elements in group 1: hydrogen, lithium, sodium, potassium, rubidium, cesium, and francium. All of these (except hydrogen) are considered alkali metals. They react very easily with other elements.

∙ 9y agoThe elements in group 1A are metals. They belong to family of alkali metals. The elements are Li , Na , K , Rb, Cs and Fr.
Group 1A (or group 1 in modern notation) elements are also known as alkali metals. They have only one electron in their valence shells. They react vigorously with acids to form its stable +1 ion.
Groups are the vertical rows of the Periodic Table. Group 1A includes Lithium, Sodium,Potassium,Rubidium,Cesium, in it. These are called alkaline metals.

Where is alkali metals located on the periodic table and their group number?
The alkali metals are group 1, also known as group 1A.
Which group of the periodic table has the elements with lowest first ionization energies?
1A Alkali Metals
What is a group on a periodic table?
A vertical column on the Periodic table on the periodic table is called group. There are 18 groups on the table. These groups are also referred to as families. Each element in a group has the same number of valence electrons and, therefore, similar chemical properties (there are some exceptions though).
What is the ion of an element from group 1 A on the periodic table?
Group 1A elements lose one electron to form mono-positive cation. Eg: Na+, K+, Li+ etc.
What is group 1A the periodic table?
This group is of alkali metals including H, Li, Na, K, Rb, Cs and Fr.
What group of elements on the periodic table is most reative?
The alkali metals. Group 1A.
Where is alkali metals located on the periodic table and their group number?
The alkali metals are group 1, also known as group 1A.
In what period is hydrogen located at the periodic table?
Hydrogen is located in Group 1A of the Periodic Table.
How are the elements in group 1A on the periodic table similar?
They all have one valence electron.
Which group of the periodic table has the elements with lowest first ionization energies?
1A Alkali Metals
What are the modern groups on the periodic table?
group 1a , group 2a , transition elements , group 0 (inert gases)
What is the number of valence electron for all the elements in periodic table group 1A 1?
One valence electron.
What s block element is not located in group 1A or group 2A in the periodic table?
hydrogen

Does group 2 on the periodic table gain or lose electrons?
they will lose electron to form mono positive cation
What is the ion of an element from group 1 A on the periodic table?
Group 1A elements lose one electron to form mono-positive cation. Eg: Na+, K+, Li+ etc.
