Which monatomic ion has a charge of 1+ and the electron configuration [Kr]4d10 5s2?

SOMEONE ASKED πŸ‘‡

Which monatomic ion has a charge of 1+ and the electron configuration [Kr]4d10 5s2?

HERE THE ANSWERS πŸ‘‡

  • So first off because it is a monatomic ion you can eliminate nitrogen, oxygen, fluorine, chlorine, bromine, iodine, and hydrogen. And because it has a positive charge you can eliminate any element that is in the “p” sublevel. Because the charge plus one means it can lose one electron it means it can be pretty much any metal element. And i am pretty sure you just meant [kr] 5s2 because you can’t have 4d10 than 5s2, by order of filling 4d comes after 5s. Anyways, because 5 from 5s2 tells you that the mystery element is in the fifth period and has 2 electrons in it’s shell. Therefore you can say the element is strontium. There are no unpaired electrons and the shorthand you gave is the ground state

  • [Kr]4d10,5s2 = Cd

    Cd + e-1 = [Kr]4d10,5s1 = In1+

    answer: In1+

    unpaired atoms: 0
