Problem 91P

Determine the atomic number and mass number for each isotope.

(a) the hydrogen isotope with 2 neutrons

(b) the chromium isotope with 28 neutrons

(c) the calcium isotope with 22 neutrons

(d) the tantalum isotope with 109 neutrons

ANSWER:

Solution 91P

(a) the hydrogen isotope with 2 neutrons

Tritium

Deuterium is a hydrogen isotope consisting of one proton, one neutron and one electron. It has major applications in nuclear magnetic resonance studies.

Tritium is a hydrogen isotope consisting of one proton, two neutrons and one electron.

(b) the chromium isotope with 28 neutrons

Atoms of the element chromium (Cr) have an atomic number of 24 and a mass number of 52.

The isotopes of chromium range from 42 Cr to 67Cr. The primary decay mode before the most                        abundant stable isotope, 52Cr, is electron capture and the primary mode after is beta decay..Naturally occurring chromium
