<p>Elle va devenir une chimiste </p>
<p>DO we need the article “une” in front of chimiste? </p>
<p>but Elle est chimiste (chimiste is an adj here)</p>
<p>When you use a personal pronoun, you don’t need an article.
ex. Elle est chimiste. </p>
<p>When you use a demonstrative pronoun, you DO need an article.
ex. C’est une chimiste.</p>
<p>If my instinct and course notes from this year are correct, you could write your example either way, but without the article is preferred as it is more succinct. </p>
