1.) An ion has a mass number of 65, 36 neutrons, and a charge of +1 . Identify the element symbol, and determine the number of protons and electrons in this ion.element symbol:number of protons:number of electrons: 2.) An atom or ion has 43 neutrons , 36 protons, and 36 electrons. Identify the element symbol, and determine the mass number and charge for this atom or ion.element symbol:mass number:charge: 3.) Give the systematic name of each covalent compound. Spelling counts.SF2:
