# What is the mass number of an ion with 107 electrons, 158 neutrons, and a +1 charge?

## Answer

The mass number of an ion with 107 electrons, 158 neutrons, and a +1 charge is 266. The mass number is the sum of the number of protons and neutrons. An ion with a +1 charge has 1 more proton than electrons. This ion has 108 protons and a mass number of 266.

 107 p + 158 n = 265. Electron masses are not significant, except in the most exacting work.and besides, this is a transuranic element (at. no. >92) so why should it be important? http://answers.yahoo.com/question/index?qid=201206...
