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:
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:
1. The formal charge is the "charge" an element would have in a molecule or ion if all of the bonding electrons were shared equally between atoms. We can draw three inequivalent Lewis structures for the tellurite ion , TeO32-. The concepts of formal charge and electronegativity can help us choose the structure that is the best representation. 1. Assign formal charges to the elements in each of the structures below. Note: Count oxygen atoms starting from the left for each structure.2. The best...
