Because of its atomic number. The atomic number is a reference to how many protons an element has. Argons atomic number is 18, so it has 18 protons.
Potassiums is 19.
Argon (Ar) is the nearest noble gas to potassium.
Potassium has a larger atomic radius than argon. This is because the atomic radius generally increases as you go down a group in the periodic table, and potassium is located below argon in the same group.
No, argon and potassium are not the same. They are two different elements on the periodic table with different physical and chemical properties. Argon is a noble gas with atomic number 18, while potassium is an alkali metal with atomic number 19.
Potassium is a larger atom than argon. This is because as you move down a group in the periodic table, the atomic size increases due to additional electron shells being added. Potassium is in a lower period than argon, making it larger in size.
The modern periodic table is sorted by ascending atomic number, not mass number. Argon is heavier but has 18 protons, Potassium has 19. Same deal with Tellurium and Iodine. The table was originally laid in increasing mass but it was discovered that the properties of the elements varied periodically when they were sorted according to the number of protons.
Argon (Ar) is the nearest noble gas to potassium.
K - Potassium. Just look at atomic numbers on periodic table! potassium
Argon is in the third period of the modern periodic table.
Potassium has a larger atomic radius than argon. This is because the atomic radius generally increases as you go down a group in the periodic table, and potassium is located below argon in the same group.

Argon.
chlorine size is smaller
Errors in arrangement would occur if the elements were arranged solely based on mass in the areas of iodine and tellurium, cobalt and nickel, and argon and potassium. These discrepancies were corrected by rearranging elements based on their chemical properties, leading to the modern periodic table arrangement.
Argon has 18 protons. Hence it is the 18th element in the modern periodic table. (The elements in the periodic table are arranged in the increasing order of their atomic number and repeating properties)
Ar= argon
