No. Atomic number defines the element.
The atomic number of an element refers to the number of protons in the nucleus of the atom of that element, and is unique to each element. The atomic weight is the weight of an atom of the element compared with the weight of a single proton, and consists of number of protons and neutrons in the nucleus of the atom of that element, and different atoms of the same element can have different numbers of neutrons, and therefore more than one atomic weight: it is usually given as an average. the atomic number on an element is simply the number of protons and electrons in the element. however, it is not the total number of them.
"Fluor" is an informal name for a mineral that contains more than one element and therefore does not have any atomic number. The element fluorine has an atomic number of 9.
The atomic number the the number of protons and therefore the total positive charge in the nucleus. So the the element with the atomic number 82 has more protons and a greater nuclear charge then the atomic number of 81. More protons can mean many different things such as a smaller radius, greater first ionisation energy or greater electronegativity.
The mass number of an isotope of an element is equal to its atomic mass number. However, the atomic weight of an element is a weighted average of the isotopes that occur in the element in nature. Because almost all elements have more than one naturally occurring isotope (if they have any), the atomic weights of most elements are not integers, as mass numbers always are.
The atomic number of arsenic (As) is 33.See the Web Links and the Related Questions to the left of this answer for a periodic table and more information about this element.
The atomic number of an element determines the number of protons that are present in that element. The atomic size refers to the distance that the outermost valence electrons are from the nucleus.

Henry Moseley is the scientist who discovered that the atomic number rather than the atomic weight is more responsible for the properties of an element.
No, the atomic number of an element can't change. Because, we can identify an element by its atomic number and atomic mass. and hence they have been arranged in the periodic table on the basis of their mass number and atomic mass so , it couldn't be changed. Every element has a fixed atomic number..
Atomic number is the number of protons. Atomic mass is (mostly) the sum of the masses of the protons and neutrons (more or less).
The atomic number the the number of protons and therefore the total positive charge in the nucleus. So the the element with the atomic number 82 has more protons and a greater nuclear charge then the atomic number of 81.

The element hydrogen and more specifically its isotope, protium or 1H1
The atomic number of carbon (C) is 6.The atomic weight of C is 12.011 grams per mole.The atomic number of an element is the number of protons in the element. Carbon has 6 protons and therefore has an atomic number of 6(See the Related Links below this answer for a periodic table with more information about this element)
