i think it is an atom
Argon has 18 electrons.
Krypton (Kr) has the same number of electrons as a sulfide ion. Both have 36 electrons.
The mass number of an atom of argon is 40. This number represents the total number of protons and neutrons in the nucleus of the argon atom.
Yes, argon can be an ion in specific conditions. Argon can become a cation (positively charged ion) by losing an electron or an anion (negatively charged ion) by gaining an electron. However, argon is typically stable and does not readily form ions under normal circumstances.
The oxygen 2- ion. The oxygen 2- ion gains two electrons and acts like neon.
A chloride ion (Cl-) has the same number of electrons as a neutral atom of the element argon (Ar).
A chloride ion has the same number of electrons as a neutral atom of an element in Period 3 of the periodic table, as both consist of 17 electrons.
It doesn't become an argon atom because it (Cl-) still has 17 protons, and an argon atom has to have 18 protons.
As a neutral atom (When it is not an ion) the element argon has eighteen electrons.
Argon has the same electron configuration as a potassium ion, as both species have 18 electrons with the electron configuration of [Ne]3s²3p⁶.
Because the number of protons in chlorine atom and chloride ion are the same (17 protons). The element argon has 18 protons.
A calcium ion (Ca²⁺) has lost two electrons, resulting in an electronic structure similar to that of argon (Ar), which has 18 electrons. Both Ca²⁺ and Ar have the same electron configuration of 1s² 2s² 2p⁶ 3s² 3p⁶. Therefore, argon is the atom that shares the same electronic structure as a calcium ion.
Argon ionization energy is the amount of energy required to remove an electron from a neutral argon atom to produce a positively charged ion. In the case of argon, this energy is relatively high due to its stable electron configuration.
A chloride ion (Cl-) has the same number of electrons as a neutral atom of chlorine (Cl). The neutral chlorine atom has 17 electrons, and when it gains one electron to form the chloride ion, it also has 17 electrons but with a 1- charge.
Argon has 18 electrons.
Argon. Calcium has the electron configuration 1s2 2s2 2p6 3s2 3p6 4s2, and when it loses its valence electrons (the outermost 4s2 electrons) it has a configuration identical to argon. If you don't know about sublevels, then disregard that. Calcium has a configuration of 2-8-8-2, and when it loses its 2 valence electrons, it has a configuration identical to argon in the ground state. Hope that cleared it up
The chloride ion (Cl-) has the same electron configuration as argon (1s2 2s2 2p6 3s2 3p6) because it has gained an electron compared to a neutral chlorine atom. The chlorine atom has an electron configuration of 1s2 2s2 2p6 3s2 3p5.
