It tells you that each atom of iron has 26 positively charged protons in the nucleus and 26 negatively charged electrons in the electron shells surrounding the nucleus. There will also be approximately 26 neutrons in the nucleus depending on which isotope of iron the atom is.

A element box contains the name atomic number and what else?
In an element box, you will typically find the element's symbol, atomic number, atomic mass, and sometimes its electron configuration.
Can atoms of two different elements have the same atomic number and could they have the same mass number?
The atomic number, or Proton number, defines which element it is. So by definition, two different elements must have a different atomic number, or else they'd be the same element. Atomic mass is the number of protons + neutrons in the element's nucleus. Since the number of neutrons in the nucleus can vary, even within a single element (as isotopes) it is possible to have one isotope of one element sharing an atomic mass with an isotope of another element.
What do the atomic numbers on the periodic table indicate?
The atomic number on the periodic table (or anywhere else) tells you which element is being specified. The atomic number of an atom is the number of protons in the nucleus of that atom, and it is the elemental identity of that atom. Only the number of protons identifies an element. All the time, and every time. Nothing else.
How many neutrons are in the nucleus of a atom?
Atomic nuclei are composed of protons and neutrons. The atomic number of an element shows the number of protons in a nucleus of an atom of that element, while the atomic mass shows the average number of nucleons (either a proton or a neutron) in nuclei of that element. There can be an average because, unlike proton number, neutron number can vary from isotope to isotope. For example, carbon can have 6 or 7 neutrons and still be stable, but it always has to have 6 protons, or else it'd be a different element. Because atomic mass is equal to the number of protons and neutrons, one can find the number of neutrons by subtracting the number of protons from the total number of nucleons in a given isotope. To do this, subtract the atomic number from the atomic mass.

What does an element's atomic number tell about that element?
The atomic number is the number of protons and defines an element. It really only indicates the element of a given atom which can be linked to other properties such as atomic mass or location on the periodic table and anything else knowing the element tells you.

Where do you locate an elements atomic mass number?
On the periodic table it is above the letter name of the element. I don't know where else you would find a an atomic mass of an element. The atomic number tells how many protons and electrons are inside. The amount of protons and electrons are always the same.
What does an element number mean on the periodic table?
The element number on the periodic table corresponds to the number of protons in the nucleus of an atom of that particular element. This number is also known as the atomic number and defines the identity of the element. Elements are arranged on the periodic table in order of increasing atomic number.
How many neutrons are in the nucleus of a atom?
Atomic nuclei are composed of protons and neutrons. The atomic number of an element shows the number of protons in a nucleus of an atom of that element, while the atomic mass shows the average number of nucleons (either a proton or a neutron) in nuclei of that element.

To do this, subtract the atomic number from the atomic mass.
Does sulfur contain lead?
No. Sulfur is an element, so it's made of sulfur atoms and nothing else. It's pure.

Is the atomic number the top or bottom number?
Its the bottom number E.g. if there was a 35 at the top of.. > Cl and 17 at the bottom of.. > Cl Cl (Chlorine) would have the atomic number 17. This means it would also have 17 protons, 17 electrons and 18 neutrons. i.e 35-17 = 18 which is the number of neutrons :) Ahh the one time i listen in chemistry helps me, AND someone else!! Or atleast i hope i helped.
Which element determines the identity of an element?
The number of protons in the nucleus determines what element it is. There can be different isotopes that have more or less neutrons, and there can be ions meaning they're positively or negatively charged which means they've lost an electron or gained an extra one.
