what are the examples of physical and chemical property trends of the periodic table?

Atomic radii decrease as one moves from left to right across a period and while moving up a group. The atomic radius is the distance between the nucleus and the valence electrons.\n\nElectron affinity, ionization energy, and electronegativity increase as one moves from left to right across a period and while moving up a group. \n\nElectron affinity is the ease with which an atom can accept an electron. The halogens (F, Cl, I, etc.) have the highest electron affinity, with F having the highest of all elements. The alkaline metals (Li, Na, K, etc.) have the lowest electron affinity, with Fr having the lowest of all elements.\n\nIonization energy is the energy needed to remove an electron from an atom. All atoms want to form a stable octet. Since alkaline metals only have one valence electron, it takes very little energy to remove an electron from them. In contrast, it takes a lot of energy to remove an electron from a halogen.\n\nElectronegativity is the strength of the attraction an atom has for an electron in a chemical bond. Halogens are the most electronegative, while the alkaline earths are the least. The electronegativity of two elements can inform you of what type of chemical bond they will form. If Na (low EN) and Cl (high EN) form a bond, Cl will rip the lone valence electron away from Na, forming an ionic bond. If C and O form a bond, the atoms will share electrons because their EN's are very close. Since O is more EN, it will have a slight negative charge, and the bond will be a polar covalent bond. If C and C form a bond, both have the same EN, and they will form a non polar covalent bond.

Traditionally, metals have certain characteristic physical properties: they are usually shiny (they have "lustre"), have a high density, are ductile and malleable, usually have a high melting point, are usually hard, and conduct electricity and heat well. However this is mainly because the low density, soft, low melting point metals happen to be reactive, and we rarely encounter them in their elemental, metallic form. Metals are also sonorous, which means that they conduct sound well.\n\nAnd not all metals are magnetic!\n\nPalladium is a soft silver-white metal that resembles platinum. It doesn't tarnish in air. Palladium is the least dense and has the lowest melting point of the platinum group metals. It is soft and ductile when annealed and greatly increases its strength and hardness when it is cold-worked. Palladium is chemically attacked by sulfuric and nitric acid but dissolves slowly in hydrochloric acid. This metal also does not react with oxygen at normal temperatures.

You should try the "Physics Handbook", the "Handbook of Thin Film Technology"\n\nThe Handbook of Physicochemical Properties of the Elements (but this one may be available only in russian).\n\nYou may also try this article in an university library:\n\nL. Vitos, A. V. Ruban, H. L. Skriver, and J. Kollar, The surface energy of metals, Surf. Sci. 411, 186 (1998).

Changes that don't involve chemical reaction. Example: chenge in state (solid, liquid, gas), temperature change, etc. Ofcourse temperature change will initiate density change.. density is another physical property.

There are two broad classifications:  physical properties and chemical properties.  Physical properties include the solid, liquid, and gaseous phases (mostly).  Chemical properties, on the other hand, are many and varied.  There's organic and inorganic, biochemical, petrochemical, there are some based on a particular anion (nitride, oxide, phosphate, etc.); it all really depends on how specific one wants to be and what one is attempting to do or study.  \n\nThe analysis of matter is also broad:  there is structural analysis of both atoms and molecules (how is it put together?), there is quantitative analysis (how much is present?), and there is qualitative analysis (what is it?).

It depends on what you mean by "properties."  Mass is determined by the number of protons & neutrons in the nucleus.  That also relates to melting point and boiling point, though other factors affect those, too.  But the CHEMICAL properties are determined by the electrons, and specifically, the electrons in the outer shell (and next to outer shell, for the transition elements).  It's those electrons that determine if an element is a metal or nonmetal, what elements it will form bonds with, how reactive it is, etc.

a physical property is something you can see or measure.  stuff like temperature, or color.

If it counts as a chemistry discovery, the periodic table is definitely the most important.  It allows chemists to predict the chemical properties of known and undiscovered elements, including boiling and melting points, reactivity, and potential bonding.  It also provides the basis for determining the formulae of molecules and compounds, which is absolutely fundemental for chemistry.  Any chemist will tell you that the periodic table is an essential tool for chemistry.
