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.

Which element had the largest atom potassium or argon?

Argon has the larger atom compared to potassium. This is because argon has more electrons and a greater number of protons and neutrons in its nucleus, leading to a larger atomic size.


Is potassium or argon a larger atom?

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.


How does potassium turn into argon?

Potassium-40 undergoes radioactive decay into argon-40. During this process, a potassium atom undergoes electron capture where a proton in the nucleus captures an inner-shell electron and is transformed into a neutron. The result is the transformation of a potassium atom into an argon atom by emitting an electron and an antineutrino.


How does an atom of 40 potassium differ from an atom of 40 argon?

An atom of potassium has 19 protons and 21 neutrons, while an atom of argon has 18 protons and 22 neutrons. This means their atomic numbers are different, leading to distinctive chemical properties. Potassium is a metal, while argon is a noble gas.


Why does the argon atom has a lower atomic number but a greater massnumber than the potassuim atom?

Argon has a lower atomic number than potassium because it has fewer protons in its nucleus. However, argon has a greater mass number than potassium because it has more neutrons in its nucleus. The mass number of an atom is determined by the sum of protons and neutrons in its nucleus.
