The number of protons in isotopes of an element is the same.The mass number of an isotope tells you the number of protons plus the number of neutrons. Mass number = number of protons + number of neutrons â¢ Carbon has three isotopes: carbon-12, carbon-13, and carbon-14.
The 2nd time gap was long and came during Gaiden when Sarada and Boruto were 11 and by the time The Last : Boruto The Movie was aired, Boruto and Sarada were already 12 thus making Sasuke 33 years old at the final movie.
Well maybe so that naruto understood the pain of losing someone. Naruto never had anyone who cared when he was a kid, but he hadn't technically seen someone very close to him, die. Yeah, Sarutobi did die, but Jiraiya was much more close to Naruto. Sasuke always told Naruto that he would never understand Sasuke' s pain of losing everyone, frankly because he hadn't lost anyone. He just didn't have anyone in the first place.
