This ion is an cation anion What is the chemical symool of the noble gas this ion is isoelectronic with? What is the formula of the ion?

Answer 1

Solution; an A monanomic ion with electronic configuration a charge of -1 has of ls²2s²2pb3s²3pe. & The ion Because 7 So, the is an l'anion! I the charge on ion ions with a ve is -1 charge are called anion. * iso electronic: The ions having same number of electrons but different magnitude of nuclear charge are called iso-electronic jousee so the ion with electronic configuration 152 252 2p635²3 pb contains 18 electrons. so, the nobel gas that is iso-electronic the given ion is Argon (Ar) Argon has 18 electrons. with What is the chemical symbol of the nobel gas this. e ion iso-electronic with ? I Ar » What is formula Formula of of the the ion ion? Teri = ciu
