Total count of protons + neutrons. To be really anal, it is an average of the weights of the atomic nuclei of a specific element from the known isotopes of that element. Notice on a periodic chart the naturally occuring elements have weights in fractional (decimal) units, while most synthetic (man-made) elements are integers (whole) numbers as little to nothing is known about their isotopes.
Atomic Weight = Atomic Number (proton count) + neutron count
What else can I help you with?
What do the atomic number and atomic mass tell you about an atom?
Atomic number tells the number of protons and electrons, but i don't remember for atomic mass.
What does the atomic mass tell you about the atom?
The Atomic Mass of an element tells you the average mass of an atom in the element.
What does an element's atomic mass tell about the atoms that make up that element?
Atomic Mass is the no. of protons+no. of nuetron
What do the atomic number and mass number tell you about an atom?
Atomic number tells the number of protons and electrons, but i don't remember for Atomic Mass.
What do the atomic number and mass number tell about an atom?
Atomic number tells the number of protons and electrons, but i don't remember for Atomic Mass.
What does an element's atomic mass tell us about the atoms that make up that element?
atomic mass is the no. of protons+no. of nuetron
What is the actual weight of Mercury?
It really depends on how much mercury you have for me to tell you the correct weight, but if you search a periodic table of elements, it would tell you the atomic mass correctly
What information does the periodic chart tell you?
Symbol Name Atomic Number Atomic Mass
How do you tell figure out the atomic mass?
Atomic mass is the number of protons + the number of neutrons in the nucleus of an atom. On the periodic table, the average atomic mass of an element will the be number at the bottom of each box.
What does the atomic mass of an element tell?
The gram atomic weight or gram Atomic Mass of a chemical element is the mass in grams of Avogadro's number of atoms of the element with the isotopic proportions found in nature.
What does the decimal tell you in an atomic mass?
that there are stable isotopes of that element
What is the atomic mass of an atom with 5 electrons?
you can't tell the atomic mass of an atom if either the number of protons or neutrons is missing. But Boron with 5 protons and 6 neutrons has and atomic mass of 11.
