Classes of objects. the Supernova Engine. Bounce Masses. Mass at Explosion. Fallback . Neutron Star Masses. Observations of neutron star binaries provide a growing list of neutron star mass estimates.. Current observations predict a range of NS masses from 1.0 to >2 solar masses.. Isotopes. Isotopes. : atoms of the same element that have different numbers of neutrons. Two isotopes of an element will have the same atomic number, but different mass numbers (and atomic masses). CARBON (above right). Jasmine . Sudhu. 5/30/13. Chemistry 10.. What are Isotopes?. Isotope – Is the average mass of atoms. You round of the atomic mass to the nearest whole numbers to get your two possible Isotopes.. Example – Boron- Atomic mass = 10.81. After rounding to the closet two whole numbers which are 10 and 11, your . What is it?. 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.. Introduction . to Spectroscopy. Spectroscopy involves an interaction between matter and light . (EMR). Light can be thought of as waves of energy or packets (particles) of energy called photons. Properties of light waves include wavelength and frequency. What number equals the number of protons?. Atomic Number. From the periodic table – . How is the mass of a “regular” (most abundant) atom determined?. Protons Neutrons = Atomic Mass. An Isotope is defined as…. III. How atoms differ. . A.
