1 periodic table of elements and their compound by law degeneration
1.1 Atomic radius
(1) Subject to paragraph 1 cycle,the other cycle elements (except for the inert gas elements) of the atomic radius decreases with increasing atomic number;
(2) the elements of the same family from top to bottom,with electronic layers increased,atomic radius increases.
Valence of 1.2 elements
(1) In addition to a cycle,with the cycle from left to right,elements of the highest-price increase by the alkali metal +1 to +7,non-metallic elements in the negative price increment by the carbon group -4 to -1 (F has no positive value,oxygen-free +6 price excluded);
(2) the same main group elements in the highest positive value,negative prices are the same
1.3 the melting point of a single quality
(1) the same cycle of elements with increasing atomic number,elemental metal elements increase the melting point,melting point of diminishing non-metallic simple substance;
(2) from top to bottom with the family element,the element composition of the metal decreases the melting point of a single mass,increasing the melting point of non-metallic elemental
1.4 Elements of metallic and nonmetallic
(1) the elements of the same period decreased from left to right metallic,non-metallic nature of increments;
(2) the same metallic main group elements increase from top to bottom,non-metallic nature of decline.

1 periodic table of elements and compounds the deferred degeneration rule
1.1 atom radius
(1) except the 1 cycle outside, other cycles elements (inert gas elements with the exception of atomic radius of atomic number increasing and decreases,
(2) in the same group elements from top to bottom, with the electronic number increase, atomic radius increased.
The remnant 1.2 elements
(1) except the 1 cycle outside, with periodic from left to right, the highest by alkali metal elements at original + 1 to + 7, increasing nonmetal negative price of carbon race - 4-1 (fluorine increasing, oxygen is no general + 6 price, except),
(2) the same main group elements of the highest price are the same general, negative
130 elemental melting point
(1) the same cycle elements with atomic number increasing, elements of the metal elemental melting point of increasing, non-metallic elemental melting point of diminishing,
(2) in the same group elements from top to bottom, elements of the metal elemental melting-point descending, nonmetal elemental melting point increase
1.4 elements of gold attribute and nonmetal sex
(1) the same cycle elements from left to right gold attribute descending, nonmetal sex increasing,
(2) the same main group element from top to bottom gold attribute increments, nonmetal sex is degressive.
