Example – Boron- Atomic mass = 10.81. After rounding to the closet two whole numbers which are 10 and 11, your . What’s new?. SIMS Teacher . Comments.

Isotopes are different versions of atoms having the same number of protons but different numbers of neutrons.. Atomic Mass. The mass of each isotope is different due to the different number of neutrons.. GLY 4200. Lab 2 - Fall, . 2016. 2. Native Elements. The native elements may be divided into metallic, non-metallic, and semi-metallic. Native elements are composed of a single element, uncombined with other elements. Objectives of the presentation.
