Regarding the modern periodic classification of elements, identify the true statement:
In a family, elements generally have the same number of electrons in the last shell.
In the periodic table, the chemical elements are placed in descending order of atomic masses.
In a family, elements have very different chemical properties.
In a period, the elements have similar chemical properties.
All representative elements belong to group B of the periodic table.
All are wrong.
The Periodic Table is a table that groups all known chemical elements. In the periodic classification of elements, one takes into account:
The size of the atom of each element
The number of electrons in the electron shell of the atom
The atomic radius of each element
The number of protons in the atomic nucleus
The properties of the elements are a periodic function of their:
Atomic mass
Atomic number
Atomic diameter
Oxidation number
Atomic and ionic radi
None of the above
The sodium atom, whose atomic number is 11, is classified in the Periodic Table as:
Transition metal
Chalcogen
Noble gas
Alkali metal
How are the elements listed sequentially in the Periodic Table?
In order of increasing atomic mass
In order of increasing atomic radius
In order of increasing atomic number
In increasing order of electronegativity
