What property is different in and isotope of an element?
Isotopes of elements vary by number of neutrons and thus by mass.
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.
Why is atomic number better than atomic mass for organizing the elements in the periodic table?
Atomic number is a unique number for each element. No two elements have the same atomic number. Atomic number is also the number of protons in the nuclei of the atoms of any given atom. Atomic mass, however, is the number of protons, neutrons and electrons. The number of neutrons can vary with different isotopes of the same element, this means that atomic mass can vary with different isotopes. So atomic number does not vary, but atomic mass does, so it is more logical to use atomic number to organize the elements. In addition, when the elements are arranged according to atomic number into seven rows and 18 columns, it becomes evident that there are certain trends that occur across the periods, and that elements in the same group have similar properties.
What are all elements are mixtures of?
An element is composed of atoms all with the same proton number(they are the same type). The only way the atoms in an element can vary is in the number of neutrons they have.
how isotopes can have different masses and still be the same element?
For the same element the number of protons and electrons remains unaltered. Howerm for that same element the number of neutrons can vary., leading to different atomic masses. Taking hydrogen as an example. It has three isotopes. #1 ; protium ; 1 proton , 0 neutrons (Atomic Mass ; 1 + 0 = 1 ) #2 ; deuterium ; 1 proton , 1 neutron ( Atomic mass ; 1 + 1 = 2) #3 ; tritium ; 1 proton, 2 neutrons ( Atomic Mass ; 1 + 2 = 3) Notice for each isotope of hydrogen there is only ONE proton. However, for each different isotope of hydrogen there is a different number of neutrons. The Atomic Mass is the sum of the protons and neutrons). #4 ; Helium(He) ; 2 protons, 2 neutrons ( atomic mass 2 + 2 = 4 ). For comparison helium has 2(TWO) protons and 2 neutrons, but it is an entirely different element, because it has a different number of protons.

How can Atoms vary?
Atoms and elements can vary in many ways. Atoms mainly vary by having different numbers of protons, electrons, and neutrons. The count of protons makes up an elements 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.

Can an atom of two different elements have the same mass number?
Yes. The mass number is basic to the different elements, even more useful than the atomic number. (Unless it is an isotope. Isotopes have a different amount of neutrons than the basic element atom which makes a difference in mass number too. So, a difference in mass numbers doesn't always mean it is a different element.)
What is the atom with same atomic number but different mass number?
We can find atomic mass and mass number in chemical elements. Atomic mass is about weight of the atom. Mass number is about total of neutrons and protons.

What makes isotopes different from elements on the periodic table?
isotopes of a given element have the same atomic number (or number of protons) but vary in the number of neutrons and hence the mass number.
How small is a quarks?
Quarks can actually vary greatly in size. The most common types of Quarks are Up and Down (scientists are not the most creative when it comes to names) and they have the mass of about 1/400 and 1/200 (respectfully) the mass of a proton. But some quarks, like the Top quark (another uncreative name) has the mass of the entire Tunston atom.
How do you atomic masses vary throughout the periodic table of elements?
Each element has its own atomic mass.

What is a proton and neutron?
A proton is a positively charged subatomic particle found in the nuclei of atoms. The number of protons an element has in its atomic nuclei is its atomic number, and defines the element. A neutron is a subatomic particle that has no charge and is also found in the nucleus of an atom. The number of neutrons in the nuclei of an element can vary. Atoms of the same element that have different numbers of neutrons, giving them different mass numbers, are called isotopes.
