Every elements has atomic number, elements identity determined the number of protons in its nucleus.
Yes.
The elements with atomic numbers between 57 and 71 are called lanthanoids (or lanthanides).
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.)
Elements which have two or more different types of atoms are known as multi-atomic elements. eg; HClO4, HNO3 etc.
No two different elements can have the same atomic number.
Granite is a compound. They do not have atomic numbers. It is for elements.
The mole is the atomic weight expressed in grams.
Moseley's law
Mendeleev
I think that the ionic radii decrease
the atomic number is equal to the number of electrons(-) and protons(+): that is why elements have no charge, as a neutron is neural
Proton number, which is an element's atomic number, identifies an element. Each element has a unique atomic number (number of protons).
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.
Generally the term "atomic mass" is used for isotopes. For elements is preferred now "atomic weight".
