What happens during the fourth stage of technological design that is not necessary during the sixth or seventh stages of scientific investigation? A design is remodeled after analysis and tested again.
An initial design is implemented and analyzed to gather data.
Conclusions are made and communicated to others.
Criteria are stated to help judge the success of the process.

The table compares the number of electrons in two unknown neutral atoms. comparison of electrons atom number of electrons a 9 d 11 use this information to determine the number of valence electrons in the atoms. which of the following correctly compares the stability of tthe table compares the number of electrons in two unknown neutral atoms. comparison of electrons atom number of electrons a 9 d 11 use this information to determine the number of valence electrons in the atoms. which of the following correctly compares the stability of the two atoms? both are unreactive. both are highly reactive. a is unreactive and d is reactive. a is reactive and d is unreactive.
