Mokslas geriau įsimena, kai apibrėžimas susiejamas su tuo, ką galima išmatuoti ar stebėti.

Table salt is not made of isolated NaCl molecules in the solid; it forms an extended ionic lattice.

5

Water is bent rather than linear, so its bond dipoles do not cancel and the molecule is polar.

Konkretus patikrinimas

Atoms form bonds because different arrangements of electrons and nuclei can be energetically favourable. Bond polarity and three-dimensional geometry then shape molecular behaviour.
