Every individual block on the Periodic Table ... all hundred-and-some of them ...
represents an atom, with a structure different from all the other ones.
Hydrogen is the least massive element. It is found in group 1, period 1 on the periodic table.
On the far left on the periodic table.
halogens are located in 17th group of the periodic table or 2nd group from extreme right.
Hydrogen, lithium, sodium, potassium, rubidium, cesium and francium are the elements located in group 1 of the periodic table.
In English please ?I
The most reactive metals will be found in Group 1 on the right side of the periodic table.

On the far left on the periodic table.

Potassium is in group 1 of the periodic table, so the answer is 1 electron.
This was done only save space. Because there are so many elements in each Group (Group IIIB)--numbering 14 each--the Periodic Table would be twice as wide than as we know it.
the group number of the periodic table shows the valence electron. such as :- sodium is placed in group 1 and have valence electron.
In Group 1. (The extreme left of the modern Periodic Table)
Hydrogen, lithium, sodium, potassium, rubidium, cesium and francium are the elements located in group 1 of the periodic table.
Xenon (Xe, atom number 54) is found in period V of Group 18, the group of "inert" gaseous elements, noble gases.
Mendeleev left blank spaces because certain elements on the Periodic Table were not known at that time. He knew that in the future, those elements would be found and placed on the periodic table.
