Atomic Mass of Iron An element's atomic mass is equal to the sum of the individual particle masses of an atom. Atoms have three basic particles which include protons, neutrons, and electrons. The standard unit for measuring atomic mass is the Dalton (u). ...
The atomic mass unit (AMU or amu) of anelementis a measure of its atomicmass. Also known as thedalton(Da) orunified atomic mass unit(u), the AMU expresses both atomic masses and molecular masses. AMU is defined as one-twelfth the mass of anatomof carbon-12 (12C).12C is the most a...
Atomic Structure: Atoms are the smallest units of matter that still retain the properties of their element. Atoms are made of neutrons and protons in a nucleus with electrons orbiting around it. Answer and Explanation:1 The mass number of iron is 55.845amu. The mass number is equal to the ...

Mass Number It is the sum of neutrons and protons of an atom present in nucleus. Mass Number for two different atoms can be same. The Atomic Mass of an atom is approximately equal to its Mass Number as mass of a neutron as well of a proton is one unit on atomic mass scale.Email...
Lithium has an atomic mass of 6.96. There are only two natural isotopes of Li: Li-6 and Li-7. What is the percent of each isotope present? Lithium has two naturally occurring isotopes, 6-Li and 7-Li, with masses of 6.015 amu and 7.016 amu...
What Is Atomic Mass [/caption] The answer to ‘what is atomic mass’ is this: the total mass of the protons, neutrons, and electrons in a single atom when it is at rest. This is not to be associated or mistaken for atomic weight. Atomic mass is measured by mass spectrometry. You ...
