The mole is the atomic weight expressed in grams.
Simply, the atomic number and the number of protons are the same. If the atomic number is 8, then there are 8 protons in the element.
Each element has an atom that has different amounts of protons, neutrons, and electrons. This is the case for the element's atomic number and atomic mass. They are arranged by their differences on the periodic table of the elements. Most elements are metals. The three categories for the elements are metals, nonmetals and metalloids. ----
Atomic number is the no. of protons or no. of electrons in an atom .
More electrons, protons, neutrons and a greater atomic weight.
Atomic number is the number of protons in the nucleus of an atom. All of the atoms of the same element have the same number of protons, and therefore the same atomic number. For example, all hydrogen atoms have one proton in their nuclei, and hydrogen's atomic number is 1; and all carbon atoms have six protons in their nuclei, and carbon's atomic number is 6. Each element's identity is determined by its atomic number. The relationship between the periodic table and atomic number is that the elements are arranged in the periodic table according to increasing atomic number, starting with hydrogen and ending with Ununoctium, which has an atomic number of 118.
The atomic number is the number of protons the element possesses.
A German chemist Dobernier observed relationship between atomic masses of several groups of three elements called traids.In these groups the central or middle element had atomic mass average to the other two elements.
Every elements has atomic number, elements identity determined the number of protons in its nucleus.
Electron configuration is the arrangement of elements according to their increasing atomic numbers whiles period is the arrangement of elements according to the increasing number of valence electrons.
Proton number, which is an element's atomic number, identifies an element. Each element has a unique atomic number (number of protons).
the atomic number is the number of protons in a certain element. elements are arranged on the periodic table by atomic number in increasing order
Atomic number: number of protons in a nucleus unique to an element Atomic Mass number: number of protons + number of neutrons in a nucleus. May be a small range of values for a given element. Very roughly the atomic mass number is double the atomic number. For large elements it is more than double.

The atomic number of a chemical element is identical to the number of protons.
Oxygen (15.9994) Flourine (18.9984032)
Simply, the atomic number and the number of protons are the same. If the atomic number is 8, then there are 8 protons in the element.
Each isotope of an element has an atomic mass. The average of all the atomic masses of an element's isotopes gives an elements atomic weight. For this reason, atomic weights are decimal numbers.
