In chemistry and physics, the atomic number of a chemical element is the number
of protons ... The atomic number, Z, should not be confused with the mass
number, A, ... of elements creates an orderi...
The atomic number represents the number of protons present in the nucleus of
an atom. The atomic number of an element is located on the upper-left corner of ...
After reading this section you will be able to do the following: ... The number of
protons in the nucleus of an atom determines an element's atomic number.
The atomic number of an atom is the number of protons it contains. ... Note that
you can work out the number of neutrons from the mass number and atomic ...
The atomic number is the number of protons in an atom, and isotopes have the
same ... If you want to calculate how many neutrons an atom has, you can simply
.... Carbon-14 is not usable for nearly all fossils because there isn't enough ...
No. The atomic number (number of protons in the nucleus) DEFINES the
elements, so if it ... You could measure the protons in an element's nucleus, and it
DID give you its place on the table. ... the mass of different atoms of the same
element can be different, but not ... What do atomic numbers tell you about an

types of subatomic particles, they are not all the same size. ... mass of a carbon-
12 atom (a carbon that has 6 protons and 6 neutrons). ... you can see, the mass of
a proton and the mass of a neutron are almost .... The periodic table does not tell.
If you were somehow able to change the proton number of this atom to 7, even if
everything ... It is NOT always the same as the number of protons and electrons.
... Because we can find the number of protons and the atomic mass of an atom by
The atomic number will tell you how many protons make up a single atom of an ...
a negative or positive ion, then the protons and electrons will not be the same.
That is not meant to be an insult; more of an example of how you are made up of
atoms ... Atoms of the same element can have different numbers of neutrons.
