Problem

Osmium has six naturally occurring isotopes. When the most abundant isotope has this symbol:

190Os6+

The atomic number (Z), mass number (A), number of neutron (n) and number of electrons are:

A) Z=76, A=114, n=190, e=76

B) Z=190, A=76, n=114, e=76

C) Z=76, A=76, n=114, e=82

D) Z=76, A=190, n=114, e=70
