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.

Is argon and potassium the same?
NO!!!! They are two different elements found in the Periodic Table. Argon is a Noble(Inert) gas Potassium is a highly reactive metal, when placed in oxygen or water.
Why is argon obtained before oxygen?
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.
Why is argon 18th in the periodic table?
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)
What is the nearest noble gas to potassium?
Argon (Ar) is the nearest noble gas to potassium.
Which element had the largest atom potassium or argon?
argon
What period is argon in?
Argon is in the third period of the modern periodic table.
If argon is 18 then what is 19?
K - Potassium. Just look at atomic numbers on periodic table! potassium

What is an unreactive gas that sinks in the air?
Argon.
What element has more protons than chlorine but fewer than potassium?
Argon, atomic number 18, since it is between chlorine and potassium on the Periodic Table of Elements.
Which is smaller in size chlorine or argon in modern periodic table?
chlorine size is smaller
What is the nearest noble gas to potassium?
Argon (Ar) is the nearest noble gas to potassium.
Which element had the largest atom potassium or argon?
argon
State which two elements from the first 20 elements of the modern periodic table are not arranged in order of increasing atomic mass?
Took me a while to find but you can spot it eventually. It's Argon (Ar) and Potassium (K). Hope this helps :)
What is argon is the periodic table?
Ar= argon
