Atomic Mass (not to be confused with atomic mass number) refers to the mass of a given atom of a specific isotope, and is often expressed in unified atomic mass units. Atomic mass is found by adding together the individual masses of the protons and neutrons in the nucleus (the mass of electrons is comparatively insignificant). The value displayed on the Periodic Table is a weighted average based on the relative natural occurrence of all possible isotopes of an element.
What makes atomic mass complicated is the fact that elements come in more than one isotope. Chemists need to know what a given element will actually weigh, in order to know how much to use (and so forth) when working with it in their laboratories, so the atomic mass refers to the actual weight of that element, per atom on the average. This depends upon the isotopes that exist, and also upon the relative abundance of those isotopes. It can only be determined experimentally, it is not something derived from the periodic table. You have to actually weigh the element to find out what it weighs.
*The atomic mass number of an element is the total number of neutrons and protons for a given isotope. For example 14C or carbon-14 has 6 protons and 8 neutrons.

What is the atomic mass of the element Ne?
Neon is a non meta element. Atomic mass of it is 20.
What does the atomic mass of an element measure?
Atomic mass of an element measures the mass of that element on a molecular scale, taking into account neutrons and protons, which weigh approximately 1. Electrons are negated. Atomic mass is also the mass, in grams, of 1 mole of that element.
What element that has an atomic mass of 14.007?
Nitrogen, element 7, has an atomic mass of 14.0067, rounded to 14.007.
Which element has an atomic mass of 200?
Mercury has an atomic mass of 200.
What element has an atomic mass of 50.942?
Vanadium is the element that has an atomic weight of 50.942.
How do you find the atomic mass of magnesium?
The atomic mass of every element is given in the box for that element in the periodic table of elements.
What is needed to find the average atomic mass of the element?
the mass of the isotopes
What is a reasonable value for the atomic mass of the missing element in the periodic table?
You would have to first find out the atomic mass of the number and if you wouldn't be able to find out the the atomic mass or if it doesn't have an atomic mass that means it has no electrons
What is the difference between average atomic mass and atomic mass?
What is the atomic mass for magnesiam?
Magnesium is a meta element. Atomic mass of it is 24.
What is the atomic mass of an element the number?
We can find Atomic Mass and mass number in chemical elements. Atomic mass is about weight of the atom. Mass number is about total of neutrons and protons.
How do you find the atomic mass for the element krypton?
the atomic mass is the atomic weight. look at your periodic table and you will find its 83.8 which is 84 you go to the land of mordor and drop the one ring into the fires of mount doom
How can you get the mass number and atomic number of element?
We can find atomic mass and mass number in chemical elements. Atomic mass is about weight of the atom. Mass number is about total of neutrons and protons.
Which element has the atomic mass of 126.9045?
The element is Iodine (I). It has an atomic mass of about 126.9.
To determine the number of neutrons in an atom, what must be done?
Find out the mass number (A) of the specific isotope of the element. Find out the atomic number (Z) of the element (e.g. from the periodic table). Number of Neutrons, N = A-Z.
Could Defferentiate the mass number and atomic element?
We can find atomic mass and mass number in chemical elements. Atomic mass is about weight of the atom. Mass number is about total of neutrons and protons.
How do you calculate the number of neutrons an atom of a specific element has?
First, find its atomic mass on the periodic table and subtract the number of protons (element number) from it and there you go
