What relationship exists between elements and periods according to the periodic law?
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.
Why is there a pattern between the atomic radius and melting points within alkaline earth metals or period 2 metals?
The pattern between atomic radius and melting points in alkaline earth metals or period 2 metals is due to the relationship between the attractive forces within the atoms (which decrease with larger atomic radius) and the intermolecular forces that hold the atoms together in the solid state. As atomic radius increases, the intermolecular forces become weaker, making it easier for the metal to melt at a lower temperature.
What is the atomic number for manganese?
The atomic number for Manganese is 25. It was discovered in 1774 so was one of the earlier elements discovered. It has a melting point of 1519 Kelvin.
What is the relationship between element and density?
The density of an element is a physical property that describes its mass per unit volume. Different elements have different densities based on their atomic structure and arrangement of atoms. Generally, elements with higher atomic masses tend to have higher densities.
What is the purpose of the periodic table of elements?
the purpose of it is that to know informations about the elements(e.g. atomic weight,atomic number,symbolname,oxidation state or valence electron,melting point,boiling point,density,electronegativity,year fonuded,place founded,founder, and any other informations)
Who found a relationship between the wavelengths of x-rays and the atomic number of elements?
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.
Who was the Russian chemist show a definite relationship between chemical properties and atomic weights of the elements?
Mendeleev
What is the relationship between the atomic numbers and ionic radii of the elements in the group 3A?
I think that the ionic radii decrease
What is the relationship between the atomic number and the elements identity?
The atomic number of an element determines its identity. Each element has a unique atomic number, which is the number of protons in the nucleus of its atoms. This number defines the element and distinguishes it from other elements on the periodic table.
What relationship exists between elements and periods according to the periodic law?
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.
What is the law of traid?
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.
What is the relationship between an atoms atomic number and one mole of that atom?
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.
Why is there a pattern between melting point and atomic radius?
A relation doesn't exist.
What is the biggest jump in atomic weights between consecutive elements?
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.
Why is there a pattern between the atomic radius and melting points within alkaline earth metals or period 2 metals?
The pattern between atomic radius and melting points in alkaline earth metals or period 2 metals is due to the relationship between the attractive forces within the atoms (which decrease with larger atomic radius) and the intermolecular forces that hold the atoms together in the solid state. As atomic radius increases, the intermolecular forces become weaker, making it easier for the metal to melt at a lower temperature.
Is there a difference between mass and atomic mass when dealing with elements?
Generally the term "atomic mass" is used for isotopes. For elements is preferred now "atomic weight".
What is the atomic number for manganese?
The atomic number for Manganese is 25. It was discovered in 1774 so was one of the earlier elements discovered. It has a melting point of 1519 Kelvin.
