( Discovery of Nucleus in an atom )
Ernest Rutherford was interested in knowing the arrangement of electrons in an atom. For this, he conducted a unique experiment of scattering of positive charged Alpha particles by a gold foil.
Infact, alpha particles are nuclei of helium atom, with two units of positive charge and four units of mass. These particles are emitted by radio active elements like Radium and potassium. Fast moving alpha particles have considerable amount of energy and they can penetrate through matter to some extent.
He used a gold foil which is very malleable element and can be stretched to extreme thin sheet.
He bombarded the alpha particles over the gold foil which was about 1000 atoms thick.
\large{\underline{\sf{Observations:-}}}
Observations:−
This experiment gave the scientist totally unexpected results. He made following observations:
Most of the fast moving alpha particles passed straight through the gold foil.
Some of the alpha particles were deflected by small angles while passing through gold foil.
Very few of the (one in every 12,000 particles) appeared to rebound it's original path.
\large{\underline{\sf{Conclusions:-}}}
Conclusions:−
There should be large enough space inside the atom, so that most of the alpha particles passed away without deflection.
There should be positively charged heavy body inside the atom, It is so that alpha particles which are positively charged themselves could be deflected by only positively charged body.
Heavy, positively charged body should be present inside the atom at its centre. It is so because passage of alpha particles through gold foil was uniform.
Positive charged body of atom must contain all the mass of atom also. Due to this, it becomes very heavy and deflects the alpha particles to 180°.
Size of positively charged body must be very small because of alpha particles came to their original path. (i.e at 180°)

Answer:
Last summer our family went to a memorable picnic at a nearby water park. The day when we spoke for the first time about going to a picnic, the adrenaline rush has been started flowing within us. The flow of happiness amongst the family was at its peak while preparing for the picnic. Everybody was excited about this outdoor adventure. Finally, the day had arrived. We all left our home and soon were on our way to the picnic. The car was full of chatters. Every family member was so excited about the picnic with the family. All of us were in a totally different form.
Finally, we reached our destination. The moment we reached the ticket window, the kids in the family started jumping with excitement. While we were purchasing the tickets, the kids started getting restless to wait. Then we entered for our awaiting adventure for the picnic with the family. As soon as we entered, the beauty of the place welcomed us with a cool breeze on our faces.
We put on the costumes and entered the pool. The coldness of the water was soothing one. Each splash brought a smile on everyone’s face. Everybody went back to their childhood. The youngest one in the picnic with family was 3.5-year-old, who had entered the pool for the first time. He was the happiest amongst all. After spending a considerate amount of time playing with water, we had to struggle a lot to take kids out from the pool. What a memorable time it was during a picnic with the family.
hen we started heading towards the food zone. The fun in the pool has led to an empty stomach which was making a lot of funny noise. And the aroma of the delicious food which was coming from the food zone had aced our pace towards it.
The kids in the family started making a list of all the things that they wanted to eat. We ordered everyone’s favorite dish and sat waiting for the food to come. This waiting time was the most torturous one. And finally, our hot and tasty food came. We literally attacked it like the hungry animals. The next 30 minutes was complete silence. Everybody in the picnic with family was busy enjoying their own favorite delicacy. We finished eating and left for home.
Though the picnic with family was over, still it is alive in over memories. All the good time we spent together, a lot of beautiful pictures, will always be with us in our memories. We will soon plan our next picnic with family to rejoice our love, bonding, and happiness together.
