During a fun chemistry quiz, Hannah, Elijah, and Mia are trying to solve a tricky question about 'Atomic Number'. Hannah thinks it's 'the number of protons AND neutrons in an atom's nucleus', while Elijah believes it's 'the number of protons in an atom's nucleus'. Mia, on the other hand, has two different ideas: 'it's always the same number as the number of valence electrons for an atom of an element' and 'it's always less than 50'. Who among them got it right?

• Hannah: the number of protons AND neutrons in an atom's nucleus

• Elijah: the number of protons in an atom's nucleus

• Mia's thought: always the same number as the number of valence electrons for an atom of an element

• Mia's thought: always less than 50
