What does atomic mass number tell us?
Type your answer here..The Atomic Mass Unit tells us that ,How heavy a substance as compare to the other.
What is the mass number of cl35?
The mass number of the element chlorine is 35.5. The mass number (nucleon number) of an isotope of an element tells us the sum of the number of neutrons and protons. It is a decimal because mass numbers of elements are averages, based on the different isotopic forms of the element and their relative abundance.
What does the mass number tell us about and element?
it tells you how much mass is in that object
What do the groups tell us about the elements?
it tells if its a solid - gas - liquid
What does the atomic mass or mass number tell you about an atom?
As a first approximation it tells us simply the total number of protons and neutrons in the nucleus. The electrons and binding energy of the nucleus contribute a very much smaller amount to the mass. Since the number of protons in a given element is constant (the atomic number), we can also tell the number of neutrons in an atom by subtracting the atomic number from the atomic mass (approximately). Since different isotopes of each element have different numbers of neutrons (but the same number of protons), they will have different atomic masses. The given atomic weight for a particular element is usually based on the relative abundance of the isotopes as they occur in nature. It is also true that elements with very high elemental weights tend to be unstable, that is, radioactive. (Referring to the Wikipedia entry on "atomic mass" I see that what I have defined here may include some of the sense of "atomic weight", however the difference is subtle. See that entry for further clarification.)
What does the atomic number number tell us about an elements?
The atomic number is the number of protons in the nucleus.The Atomic Number of an element helps us to locate that particuarler element on the Periodic Table of Elements.
What does the mass number of an atom tell you about the atom?
The mass number tells us the number (the sum) of protons and neutrons in the nucleus of an atom.
What are the orientation of elements in the peridoc table tell us the arrangement of the what?
The periodic table is in order of atomic mass
What does the atomic mass tell us?
it tells us that the number is equal to the number of protons plus the number of nuetrons in the nucleus of an atom
What does atomic mass number tell us?

What does the atomic number tell us about an element?
The atomic number is the number of protons in the nucleus.The Atomic Number of an element helps us to locate that particuarler element on the Periodic Table of Elements.
What does the mass number tell us about lithium?
It tells us the total mass of Protons and Neutrons, in AMU, Atomic Mass Units.
What is the number of neutrons from a mass number of 10?
Need the atomic number - that would tell us the number of protons and from there the number of neutrons can be calculated. The question as posed does not have enough information to answer.
What does an element's atomic number tell us?
The atomic number is the number of protons that the element has.
What is the mass number of cl35?
The mass number of the element chlorine is 35.5. The mass number (nucleon number) of an isotope of an element tells us the sum of the number of neutrons and protons. It is a decimal because mass numbers of elements are averages, based on the different isotopic forms of the element and their relative abundance.
What does the mass number tell us about and element?

What does a period on the periodic table tell us?
Elements in the same period has same number of valence shells.There are 7 periods in Periodic Table.
