The atomic number of an atom indicates the number of?
The atomic number is the number of protons in the atom. In the case of a neutral atom (as opposed to an ion), the atomic number is also equal to the total number of electrons.
What two things does a chemical formula tell us about a compound?
the actual number of atoms in a molecule
What is the atomic number on a table that tells us how many of what are in an atom of the element?
The atomic number of an elemnt tells you how many protons are in the nucleus and therefore how many electrons thare are in a neutral atom. The mass number is the toal of protons and neutrons.
What element has a atomic mass of 39.9?
The atomic number is the count of how many protons an atom has in its nucleus (and therefor also the count of how many electrons the neutral atom possesses). The atomic number us unique for each element and positions the element in the periodic table. The element with atomic number 39 is Yttrium (Y).
How many protons are in the isotope 235 92 U of Uranium?
235 (mass number) - 92 (number of protons) = 143 (number of neutrons)
What does the atomic number number tell us about an elements?

What does the atomic number tell us about calcium?
Calcium is a metal element. Atomic number of it is 20.
What does the atomic number tell us about an atoms?
Atomic number, being a characteristic property (property that is diff. for each element), it identifies the element, For instance, Oxygen has an atomic number of 8, and it's the only one that has that atomic number, same with any other element, except that no other element has an atomic # of 8. No two elements can share an atomic number.
What dose the atomic number tell us?
the # of protons
What does the atomic number of the atom tell us?
Atomic number, being a characteristic property (property that is diff. for each element), it identifies the element, For instance, Oxygen has an atomic number of 8, and it's the only one that has that atomic number, same with any other element, except that no other element has an atomic # of 8. No two elements can share an atomic number.
What does the period number tell us about the element?
For elements it's the atomic number not the "Period Number." This number tells you how many protons a single atom of that element has in its nucleus. The "period number" is a dimensionless quantity used in fluid dynamics.
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 four things does a periodic table tell us?
#1 ; Atomic Number (position in the Periodic Table. #2 ' The Atomic Mass #3 ; The number of protons and electrons (Same as Atomic Number) #4 ; The groups and periods of elements. #5 ; The Physical state ( solid, liquid , or gas).
