If you mean the alkali metals, these are all of them, in order:
hydrogen, lithium, sodium, potassium (the stuff in bananas), rubidium, cesium, and francium.

One example of a block element that is not located in group 1A or group 2A in the periodic table is carbon, which is a p-block element. Carbon is located in group 4A (14) of the periodic table and is known for its diverse bonding properties, forming a wide range of compounds.
Hydrogen is period 1 and group1 element. It has only one electron.
The number one element on the periodic table is hydrogen. It is not a metal, but the lightest and most abundant element in the universe.
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
The column of the periodic table is called group. It is also referred as family.
This element is francium.
Helium is the element that is placed in period 1 and group 18 of the periodic table. It is inert in nature and hence stable.
Any element in group 1
One example of a block element that is not located in group 1A or group 2A in the periodic table is carbon, which is a p-block element. Carbon is located in group 4A (14) of the periodic table and is known for its diverse bonding properties, forming a wide range of compounds.
Carbon is a chemical element with the symbol C and atomic number 6. It is nonmetallic and tetravalent—making four electrons available to form covalent chemical bonds. It belongs to group 14 of the periodic table. Carbon makes up only about 0.025 percent of Earth's crust. So, yes it is.
Valence electrons can be found in the outermost energy level of an atom, which corresponds to the group number of the element on the periodic table.
Hydrogen is period 1 and group1 element. It has only one electron.
Alkali metals. This is the most reactive group on the periodic table
To identify the valence electrons of an element on the periodic table, look at the group number of the element. The group number indicates the number of valence electrons. For example, elements in Group 1 have 1 valence electron, elements in Group 2 have 2 valence electrons, and so on.
The number one element on the periodic table is hydrogen. It is not a metal, but the lightest and most abundant element in the universe.
Group-1 elements are called alkali metals. They have one valence electron.
Cesium is in the 6th row of the periodic table. Therefore Cesium must have one electron in the 6s orbital.
