AQA Exam Question Module 1

Hiya!

I just cant get my head round that Question 1a) June'06

in an ion of plutonium 234/94 Pu has an overall charge of +1.6 x 10(to the power of -19). for this ion state the number of protons, neutrons and electrons

cheers kathrin
94 protons, hence 93 electrons. neutrons = mass no. - proton number = 234-94 = 140. I would have thought that anyway///maybe im just dead wrong though but i do edexcel :biggrin: lol
It's one less electron than that, because it has a +ve charge..
o yeah
Remember to check the data sheet if you ever get a question you're completely stuck on, it tells you on the top left corner that the charge of an electron is 1.6x10-19 C.

You know that electrons have a negative charge, so if the ion has a positive charge of 1.6x10-19 C, it must be missing one electron.
