What is Periodicity best defined as in chemistry?
The repitation of physical and chemical properties of elements periodically is called periodicity
What is the fundamental cause of periodicity observed in physical and chemical properties of an atom?
No. of electrons and mass per charge ratio which affects almost all types of periodicity... Size and volume of atoms also matters.
Who created the periodic law?
that many of the physical and chemical properties of the elements tend to recur in a systematic manner with increasing atomic number.
How is chemical activity used to separate copper from it's ores?
In order to extract copper from an ore it is necessary tp take advantage of one of its characteristic properties, its chemical activity ; Break it into smaller pieces
Does a chemical reaction change physical properties or chemical?
it changes chemical properties
Periodicity is best defined as?
The repitation of physical and chemical properties of elements periodically is called periodicity
What organization governs the periodic table?
This is the law of chemical properties periodicity.
How the periodicity of properties dependent upon the number of protons in an atom?
The number of protons is equal to atomic number. The periodicity of chemical properties depends on the outermost shell of electrons.

The number of protons is equal to atomic number. The periodicity of chemical properties depends on the outermost shell of electrons.
When Mendeleev changed the layout of the table how was he able to figure this out?
Mendeleev believed and enunciated the law of periodicity of chemical properties for chemical elements.
What is the repeating pattern of elements of their properties called?
The repeating pattern of elements of their properties is called periodicity. Elements are arranged according to same chemical properties.
What two properties are the modern periodic table based on?
Properties of elements are periodic function of atomic number. Elements with same chemical properties are grouped together.
What is the fundamental cause of periodicity observed in physical and chemical properties of an atom?
No. of electrons and mass per charge ratio which affects almost all types of periodicity... Size and volume of atoms also matters.
Who created the periodic law?
that many of the physical and chemical properties of the elements tend to recur in a systematic manner with increasing atomic number.
Is complex chemical activity a living thing?
No. It is one of the properties of life; life also has other properties.
Why are group 8 elements very few?
The arrangement of chemical elements in groups and periods is determined by the periodicity of the chemical properties. In the case of the transition state elements, there are some smaller groups because of the way the incomplete inner electron shells are filled.
