Is the word atingir the same in Brazilian and European Portuguese?

Yes

The word "atingir" is identical in meaning, spelling, and grammar in both Brazilian and Continental Portuguese. The only difference is pronunciation. In Brazilian Portuguese, the vowels are typically more open and the rhythm of speech is more "syllable-timed," making the word sound more clearly articulated. In Continental Portuguese, there is significant vowel reduction, where unstressed vowels are often shortened or nearly silenced, making the word sound much more "clipped" and rapid to a Brazilian ear.
