Iba un átomo caminado por la calle соn cara de preocupación. Un átomo conocido lo ve y le pregunta:
Qué tal amigo, ¿Por qué tan estresado?
Es que perdí un electrón, respondió.
¿ Estás seguro?
Sí, estoy completamente positivo.

I lost an electron Das verlorene Elektron A proton and a neutron are walking down the street. Due atomi si incontrano per strada. Il primo: "Come va? Tutto bene?". L'altro, mesto: "Uh.. no.. ho subito una perdita... un mio elettrone...". "Ma ne sei certo?". "Eh, si'... sono risultato positivo..." Two hydrogen atoms walk into a bar. One says, "I think I've lost an electron." The other says, "Are you sure?" The first says, "Yes, I'm positive..." Molecule 1: I just lost an electron. Molecule 2: Are you sure? Molecule 1: I’m positive. Dos moléculas están caminando en la calle y chocan. Una le dice a la otra: “¿Estas bien” “¡No, perdí un electrón!” “¿Estas seguro?” “Positivo” Two molecules are walking down the street and one starts looking around. The other asks, "What's wrong?" "I have lost my electron!" "Are you sure?" "I'm positive!" Two hydrogen atoms are at a party and bump into each other. The first one says, "Hey, grab that electron, it's mine!" "How do you know?" asks the second. "'Cause I'm positive!" the first replies. Two atoms were walking down the street. One atom says to the other one, "I've lost an electron!" The 2nd atom replies, "Are you sure?" "I'm positive."
