This model was accepted also by scientists in the 16 century , about 2 , 000 years later . Over the years , science , technology and scientific thinking have continued to develop . Scientists have carried out experiments and the results have shown what can be learned about the atomic structure . They used the new knowledge they had gained to propose updated scientific models of the atomic structure . What is the modern scientific model of the atomic structure ? Acco...  אל הספר
