isotopesatomicccvi同位素原子isotope Isotopes and Atomic Mass SCH 3U Matter, Chemical Trends and Chemical Bonding B3.2,3.1 l What are Isotopes? Two atoms are isotopes if they have the same number of protons, but they have different numbers of neutrons. This means that: Isotopes are atoms of the...
Because the mass of these nuclear particles is each approximately equal to one unified atomic mass unit (u), the sum of the protons plus neutrons is designated as the mass number ( A ). The mass of the electron is more than 1800 times smaller than the proton mass and, therefore, can ...

Atomic Weight: Atomic Mass and Isotopes Lesson Summary Frequently Asked Questions What is atomic mass in simple terms? Atomic mass takes all of the different forms of an element that exist on the planet and averages the mass of the elements. Each element tends to have several different forms...

For isotopes 1 and 2, the isotopic ratio is (2.3)ζ1=x1/x2=n1/n2; ζ2=x2/x1=n2/n1 The atomic mass of an element (or atomic weight) M is defined as the average of the isotopic masses, i.e. Mi is weighted by the atomic fraction xi of its isotope: (2.4)M=x1M1+x2M2...
