Hang on, what?

The opening sentence, "Isotopes are atoms that contain the same number of protons but a different number of neutrons.", leaves the reader wondering "...contain the same number of protons _as what_?"

Were I a particle physician I'd suggest an alternative, rather than simply balking at the ambiguity, but I rely on the scientific community to fill in the blanks here. — Preceding unsigned comment added by 1337ingDisorder (talk • contribs) 05:56, 24 February 2011 (UTC)

It means "the same number of protons as each other." But that doesn't sound as good. When it says two atoms have the same number of protons, what's unclear about that? If we said two families have the same number of children, is that unclear? SBHarris 06:03, 24 February 2011 (UTC)
