Stylized lithium-7 atom?
editThe picture of the Stylized lithium-7 atom has (3) electrons each at equal distance orbit from the nucleus, which seems misleading. Is there a case in real life where you could force all (3) electrons in lithium-7 to have equal energy and be stable in a single electron shell? Even in the bohr model, you'd expect (2) shells, not a single shell. A picture of a Quantum model of lithium-7 I think would be better. Or at least a picture showing (2) electron shells...

The Pauli exclusion principle says definitely no. However the electronic structure of the atom is not relevant to this particular article, and a more accurate diagram might get in the way of the intended meaning.

Explain jargon: numbers in parenthesis
editI noticed numbers in parenthesis, for example "1.007825031898(14)". What does that (14) part mean? It's not a common way to write numbers, so it should be explained. Mateussf (talk) 12:39, 19 June 2024 (UTC)
