Dariteori kinetik dan khususnya analisisEinstein tentang gerak Browman,diameter atom memiliki ukuransekitar 10–10 m. Itu artinya elektronakan terlihat berjarak sekitar 10.000sampai 100.000 kali lipat ukuran intidiukur dari inti atom tersebut (jikainti diibaratkan bola baseball, atomakan memiliki diameter seukurankota yang berdiameter beberapakilometer). Jadi, sebuah atomsebagian besar berupa ruangkosong.Rutherford’s experiments suggestedthat the nucleus must have a radiusof about 10–5 to 10–14 m. From kinetictheory, and especially Einstein’sanalysis of Browman movement, theradius of atoms was estimated to beabout 10–10 m. Thus the electronswould seem to be at a distance fromthe nucleus of about 10,000 to 100,000times the radius of the nucleus itself(if the nucleus were the size of abaseball, the atom would have thediameter of a big city severalkilometers across). So an atom wouldbe mostly empty space.Informasiuntuk AndaInformation for You

Nama aslinya adalah MarieSklodowska. Ia belajar Matematika,Fisika, dan Kimia di Paris. Mariebersuamikan Pierre Curie seorang ahlifisika juga. Mereka bekerja sama dalammeneliti radiasi yang dihasilkan olehbahan radioaktif dan mereka berhasilmenemukan unsur thorium yangbersifat radioaktif. Pada 1898, merekamenemukan dua unsur radioaktif baru,yaitu polonium dan radium. Untukkeberhasilan ini, Marie dan Pierre Curieserta Henri Becquerel mendapathadiah Nobel untuk bidang Fisika pada1903. Pada 1910, Marie berhasilmemisahkan radium murni danmempelajari sifat-sifat kimianya. Untukhasil kerja kerasnya ini, Marie kembalimendapatkan hadiah Nobel yang keduadalam bidang kimia pada 1911. Mariemeninggal tahun 1934 akibat kanker,yang mungkin disebabkan ia terlalulama berinteraksi dengan bahan-bahan radioaktif.Sumber:Science Encyclopedia, 1998

Enrico Fermimendapat hadiah Nobel pada 1938.Pada 2 Desember 1942, reaksi rantainuklir pertama dihasilkan olehsebuah tim ilmuwan yangdipimpinnya. Percobaan yang suksesini bertempat di lapangan SquashUniversitas Chicago, Amerika Serikat.Reaksi rantai bekerja menyerupaipenyalaan korek api. Panas yangdihasilkan oleh gesekan pada waktumematik korek api menyebabkansebagian atom terbakar danmelepaskan lebih banyak panassehingga menyebabkan reaksi terus-menerus berlangsung.Sumber:Science Encyclopedia, 1998

Iamendapatkan gelar Ph.D dariUniversitas Marburg pada 1901. Hahnmempelajari beberapa unsur radioaktif,termasuk aktinium dan thorium. Pada1917, ia dan Lise Meitner berbagipenghargaan atas penemuan logamradioaktif yang diberi nama protak-tinium. Pada 1944, Hahn mendapatkanhadiah Nobel bidang kimia untukkeberhasilannya dalam penemuanpembelahan inti. Proses pembelahaninti itu disebut fisi nuklir. Para ilmuwandi Amerika Serikat menggunakan hasilpenemuan Hahn ini untuk membuatbom atom pada awal 1940-an. Sejak saatitu penggunaan fisi nuklir untuk tujuandamai pun dikembangkan.Sumber:Science Encyclopedia, 1998Gambar 10.27Bagan PLTN dengan sistem PWRSumber:Fundamental of Physics, 2001reaktor PWRgeneratorpembangkituappipa uapgeneratorkondensatorpompapompa
