For starters he started playing very early (at 3) which is crucial if you want to be a good player. In that aspect, he's God gifted as he had dribble skills which is genetic in my opinion. Height He is short which means a low center of gravity so it's difficult to push him off the ball.

Change of pace Messi changes his pace really well. He starts slow and runs directly at the defender which means the defender has to stop & focus on him. When he reac...
Chemistry - Zinc Introduction In the periodic table, zinc is the first element of group 12. The symbol of zinc is ‘Zn’ and the atomic number is ‘30.’ In terms of availability, zinc is the 24 th most abundant element found in the Earth's crust and it has five stable isotopes. The most common zinc ore is sphalerite (zinc blende), which is a zinc sulfide mineral. Andreas Sigismund Marggraf, the German chemist, first discovered the pure metallic zinc in 1746. Interestingly, alchemists burned zinc in the air and form something different thing and they named that "philosopher's wool" or " white snow ." Salient Features of Zinc Zinc’s color is bluish-white and it is lustrous and diamagnetic metal. Zinc metal is normally hard and brittle; however, at when the temperature increases from 100 0 C, it becomes malleable. When temperature increases 210 0 C, then the zinc metal again becomes brittle and can be pulverized easily by beating. Zinc is a conductor of ele...
