How many electrons does iodine gain to achieve noble gas electron configuration?

Iodine gains one electron to achieve a noble gas electron configuration. Its electron configuration is [Kr]5s²4d¹⁰5p⁵, and by gaining one electron, it attains the stable configuration of [Kr]5s²4d¹⁰5p⁶, which is similar to the noble gas xenon.


Which element gains 2 electrons?

Oxygen gains 2 electrons to achieve a full valence shell with 8 electrons. This gives oxygen a stable electron configuration similar to the noble gas configuration.


When this element gains 2 electrons it has the electron configuration of the noble gas Argon?

The element is sulfur with 16 electrons. It gains two electrons to form sulfide ion which has 18 electrons as that of argon.


When the element sulfur forms a negative ion it has the same electron configuration as?

When sulfur forms a negative ion, it gains two electrons to achieve a full outer electron shell, making it have the same electron configuration as argon.


What element forms an ion with an electronic configuration of Ar with a -2 charge?

The element that forms an ion with an electronic configuration of Ar with a -2 charge is oxygen (O). When oxygen gains two electrons, it achieves a stable electron configuration similar to argon.


Do elements gain electrons to form a negative ion?

Yes, elements gain electrons to form negative ions. By gaining electrons, an element increases its electron count and attains a more stable electron configuration, resulting in a negative charge on the ion.


Which element is the most reactive non metal?

Fluorine is the most reactive non-metal element. It readily gains an electron to achieve a stable electron configuration, making it highly reactive.


When chlorine gains an electron what achieves a complete octet?

when chlorine gains an electron, it now now contains a full octet. this means that the chlorine element is now chemically perfect and now is stable , but not as stable as one of the Noble Gases


Which element would most likely have the Lewis dot symbol?

The element with the atomic number 17, which is chlorine, would most likely have the Lewis dot symbol because it typically gains one electron to achieve a stable electron configuration.


What Electron configuration of a fluoride ion?

The electron configuration of fluoride ion (F-) is 1s2 2s2 2p6. This is because fluoride gains one electron compared to neutral fluorine, which has the electron configuration 1s2 2s2 2p5.


What does an oxidation number of -1 mean?

An oxidation number of -1 means that the element has gained one electron, indicating that it is in its reduced state (has undergone reduction). This often occurs when an element gains an electron to achieve a stable electron configuration.


How many electrons does chlorine gain to make a noble gas?

Chlorine gains 1 electron to achieve the noble gas electron configuration of argon.
