To determine the mass represented by one unified atomic mass unit (AMU), we can follow these steps:1. Understand the Definition of AMU: One unified atomic mass unit (1 AMU) is defined as one twelfth (1/12) of the mass of on
Atomic number is the number of protons an atom has in its nucleus. Mass number is the number of protons PLUS the number of neutrons in its nucleus and is represented in atomic mass units. How do you find the atomic number? One can find the atomic number of an atom by looking at the...
The term atomic number , conventionally denoted by the symbol Z , indicates number of protons present in the nucleus of an atom, which is also equal to the number of electrons in an uncharged atom. The number of neutrons is represented by the neutron number ( N ). Because the mass of ...
What is the atomic number of the element that should theoretically be the noble gas below Rn? Find the alkali metal with a lower atomic number than antimony. A neutral atom has an atomic number of 12 and an atomic mass of 25. How many electrons are in it?
The unit that is often associated with atomic mass is called an atomic mass unit (amu). Due to the minuscule nature of the masses of the subatomic particles being measured, a unit was created that would be able to quantify the mass in a manner that could be easily represented. Both ...
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+…=∑xiMi As an example, natural chlorine consists of two isotopes of which one has an abundance of...

It does not include electrons because their mass is negligible compared to protons and neutrons. 3. Representation: - The atomic number is represented by the letter Z, while the mass number is represented by the letter A. When writing the symbol of an element, the atomic number is placed ...
