Every elements has atomic number, elements identity determined the number of protons in its nucleus.
Elements are arranged in a periodic table by atomic number, lower on top and left. Atomic masses have no direct relationship to the arrangement of atoms, although generally atoms with higher atomic numbers will have higher atomic masses. (There are at least three exceptions for atoms with atomic numbers differing by 1.)
Atomic number is the number of protons found in the nucleus of an atom. It determines the identity of an element and is used to organize elements on the periodic table. Each element has a unique atomic number.
All elements have protons and electrons. All but hydrogen have neutrons. All elements have isotopes which vary in neutrons but have the same amount of protons as the original element. Different elements never have the same amount of protons so scientists gave these elements their "atomic number" based on the amount of protons the element has. atomic number = amount of protons.
The atomic number of an element determines the number of protons in its nucleus, which in turn determines its chemical identity. Elements with different atomic numbers have different properties due to their unique number of protons.
covalent particles between the boron family share the same amount of macro particles and they end up being stable do to the fact that boron does not have a melting or freezing point and remains a liquid.
Henry Moseley found the relationship between the wavelengths of x-rays and the atomic number of elements. He proposed that the atomic number of an element is better defined by the number of protons in the nucleus rather than by its atomic mass.

I think that the ionic radii decrease
The proton number, or atomic number, is the number of protons in an atom's nucleus, and it determines the element's identity. Each element has a unique atomic number, so elements are defined by the number of protons they possess.
The relationship between elements and periods according to the periodic law is that elements are arranged in periods based on their atomic number and properties. Elements in the same period have the same number of electron shells, while elements in the same group have similar chemical properties.
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.
Yes, it is the atomic number i.e. number of protons that determines an element's identity.
There is no general exact relationship, because of the existence of neutrons in the nuclei of almost all elements and the lack of effect of neutrons on atomic number. An atom's gram atomic mass, however, is equal to the mass of one mole of the atoms in question.
The biggest jump in atomic weights between consecutive elements occurs between hydrogen (H) and helium (He). Hydrogen has an atomic weight of approximately 1, while helium has an atomic weight of approximately 4. This increase of 3 atomic mass units represents the largest jump between consecutive elements on the periodic table.
Generally the term "atomic mass" is used for isotopes. For elements is preferred now "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.
Atoms of different elements are characterized by the number of protons they contain in their nucleus, which determines the atomic number and identity of the element. The arrangement and number of electrons in the electron cloud surrounding the nucleus also vary among elements. Additionally, different elements have unique chemical properties based on how their atoms interact with one another.
