What are the six ions that have the same electron configuration as Ne?

N3- , O2- , F- , Na+ , Mg2+ , Al3+ all have the same electron configuration as Neon.


Which noble gas has the same number of electrons as an ion of barium?

There is no such noble gas with the same electron configuration as helium ion. Helium is the first noble gas, is stable and does not form ions. There can be, however, other ions such as H- or Li+ that will have the same number of electrons as element helium.


Which ion has the same electron configuration as an atom of He?

The ions of elements nitrogen (N3-), oxygen (O2-), and fluorine (F-) will have the same electron configuration as a sodium ion (Na+), which is the same as the electron configuration of the noble gas neon.


Does H and HE have the same valence electron configuration?

Hydrogen and helium have different valence electron configurations. Hydrogen has one valence electron, and helium has two valence electrons. However, hydrogen does typically form covalent bonds in which it shares an electron, and thereby gains an effective electron configuration of two, like helium. Hydrogen also can form the H+ ion which has no electrons.


What does isoelectronically mean?

Species (atoms or ions) that have the same number of electrons, and the same electron configuration, are called isoelectronic.


Do ions have the same electron configuration as noble gases?

The stable ions of all the elements except the Transition metals, Actinide, and Lanthanide series (that is the d and f block elements) form stable ions that are isoelectronic to a nobel gas by gaining or losing electrons in order to achieve an s2 p6 stable octet. For example, sodium will lose one electron to have the same electron configuration as neon, while nitrogen will gain three electrons to become isoelectronic to neon.


How will electron configuration of the atom change when the atom becomes an ion?

how will the electron configuration of the atom change when the atom becomes an iron


What atom contains 1 electron and 2 protons?

None, for it to be an atom it has the have the same number of electrons and protons. Something with 1 electron and 2 protons would theoretically be a helium ion but helium does not form ions.


Which ions has the same electron configuration of a noble gas ca or ci?

Cl- and Ca2+ has the electronic configuration of the noble gas, Ar, with 18 electrons.


Do Cl nd Ar have the same electron configuration?

No. No two elements have the same electron configuration.


Why do the elements sodium and potassium form ions with the same charge?

Because each of them can form a cation with the electron configuration of a noble gas by donating one electron to another element.


In the compound sodium fluoride NaF the sodium atom loses one electron and the fluorine atom gains one electron to form ions that have electron configurations similar to?

neon only because sodium loses an electron an its outer shell becomes empty making its configuration the same as neon and fluorine gains an electron making its configuration the same as neon as well.
