A monatomic ion with a charge of -1 has an electronic configuration of 1s22s²2p. This ion is a(n) What is the chemical symbol of the noble gas this ion is isoelectronic with? What is the formula of the ion?

Answer 1

An ion is an ctrical charige. by convention iden positive on is an atom of molecule that has a net electrical ch ce the charge of the (conaiderred negative by conven equal and opposite to that of the proton (consider por y convention), the net charge of an ion is non zero due it is total number of electrons being uneaual to its total, the number of protons. A cation is positively charged ion, w edectrons than protone while an Inion is negatively Charged with more electrons than protons. Here, a monoatomic ion with a charge of -1 har an electronic configuration of 15 252206 So, here the mono atomic ion is Fluoride ion (F). This ion is a negative ion or anion a Atoms ar ions with the same clectronie configuration arte said to be inoelectronic to each other. Fluoride ion (F-) contains lo electrons and has an electronic configuration of 15²25²26. Now, the noble gan Neon (Ne) also has the electronic confige -tion of 15²25²208 Therefore, the noble gans, Neon is inoelectronic with Fluorido ion (FP). Ugra- The chemical symbol of the noble gas, inoelectronic with Fluoride ion F-) is No. The formula of the ion is F.
