CO OZNACZA SŁOWO PROTON
Proton
Proton jest cząstką subatomową z symbolem p lub p + i dodatnim ładunkiem elektrycznym o jednym podstawowym ładunku. Jeden lub więcej protonów jest obecnych w jądrze każdego atomu. Protony i neutrony są określane wspólnie jako "nukleony". Liczba protonów w jądrze atomu jest określana jako liczba atomowa. Ponieważ każdy element ma unikalną liczbę protonów, każdy element ma swoją unikalną liczbę atomową. Nazwa protonu została przekazana przez neutralizator wodoru przez Ernesta Rutherforda w 1920 r., Ponieważ w poprzednich latach odkrył, że jądro wodorowe może być wydzielane z jądra azotu przez zderzenie, a zatem jest kandydatem na podstawową cząstkę i blok strukturalny azotu i wszystkich innych cięższych jąder atomowych. We współczesnym standardowym modelu fizyki cząstek proton jest hadronem, podobnie jak neutron, drugi nukleon, składa się z trzech kwarków. Przed tym modelem, który stał się konsensusem w dziedzinie fizyki, proton został uznany za fundamentalną cząstkę. W nowoczesnym spojrzeniu proton składa się z trzech kwantowych kwarków: dwóch kwarków i jednego kwarka.

CYTATY ZE SŁOWEM «PROTON»
Słynne cytaty i zdania ze słowem
proton.
Scientists habitually moan that the public doesn't understand them. But they complain too much: public ignorance isn't peculiar to science. It's sad if some citizens can't tell a proton from a protein. But it's equally sad if they're ignorant of their nation's history, can't speak a second language, or can't find Venezuela or Syria on a map.
It's extraordinary to think that if you walked into a room and said you had never heard of Hamlet, you would be regarded as a Philistine. But you could walk into the same room and say, 'I don't know what a proton is,' and people would just laugh and say, 'Why should you know?'
