identiteta atoma dolazi kad se promijeni broj atoma u jezgru. Za razliku od slobodnog protona, neutron n u slobodnom stanju je nestabilna cestica, koja se spontano raspada u proton, elektron i elektronski antineutrino ve: N -> p+e+ve Odnos broja neutrona N i broja protona Z u jezgru varira sa masom jezgra. 1≤N/Z ≤1,6 Pošto proton u jezgru djeluje odbojnom elektrostatickom silom na sve druge protone, a privlačne jake nuklearne sile djeluju samo između najbližih susjeda, da bi jezgro ostalo stabilno

light and other radiation by matter, as related to the dependence of these processes on the wavelength of the radiation. More recently, the definition has been expanded to include the study of the interactions between particles such as electrons, protons, and ions, as well as their interaction with other particles as a function of their collision energy. Spectroscopic analysis has been crucial in the development of the most fundamental theories in physics, including quantum mechanics, the special

ABOUT THE SUN The Sun is our nearest star. Its light and heat make life on Earth possible. When did the Sun form? Scientists calculate the Sun and solar system formed at approximately the same time, 4.55 billion years ago. This is based on the ages of the oldest objects that we have sampled from our solar system, meteorites. How did the Sun form? The solar nebula theory describes how most scientists think the Sun formed. A cloud of hydrogen and helium gas and dust existed in space. It began to

Synthesis of Methyl Orange Jineui Jung Abstract The purpose of this lab was to synthesize a synthetic dye, methyl orange. Methyl orange is a dye produced from a synthesis reaction between diazonium ions and aromatic structures. Dyes have basic structure of Aromatic N+N-aromatic, azo group. methyl orange was synthesized by coupling reaction between diazonium ion and N,N-dimethyl aniline under basic condition. Diazonium ion created from sulfanillic acid monohydrate and N,N-dimethyl aniline under
