Știința devine memorabilă când o definiție este legată de ceva măsurabil sau observabil.
Table salt is not made of isolated NaCl molecules in the solid; it forms an extended ionic lattice.
Știința devine memorabilă când o definiție este legată de ceva măsurabil sau observabil.
Water is bent rather than linear, so its bond dipoles do not cancel and the molecule is polar.
Punct concret de verificare
Atoms form bonds because different arrangements of electrons and nuclei can be energetically favourable. Bond polarity and three-dimensional geometry then shape molecular behaviour.
