1.) What is the (ionic) charge on the species listed?(Be sure to include the sign after the value)Zinc with 28 electrons
2.) Silicon has three isotopes 28Si 29Si and 30Si. What percentage of silicon atoms have a mass of 28.086 amu?
3.) Give the nuclear charge for the species described. (Be sure to include the sign after the value) Calcium with 20 neutrons
4.) Nitrogen has two isotopes one of which is nitrogen-14 with a percent abundance of 99.634% and a mass of 14.003074 amu. What is the mass of nitrogen-15?
5.) Give the mass number for the species described. Hydrogen with 2 neutrons
6.) Phosphorus has one isotope phosphorus-31. What percentage of phosphorus atoms have a mass of 30.974 amu?
I'm not just looking for answers I'm trying to understand how to do these problems. Thanks so much for the help!
