If different groups of scientist have access to the same data, how can they draw different conclusions?
scientists manipulate data to fit their hypotheses, which results in different conclusions.
scientific predictions must list every possibility, and so scientists are not technically incorrect.
scientists have different specialties and will interpret data differently, depending on their specialties.
scientific predictions are not usually testable, so this leads to different conclusions.

Scientific predictions are not usually testable, so this leads to different conclusions.  

If the scientists where given the same data they can frame different conclusions on the basis of analyzing the dependent and independent variables present in the data. The independent variable is the one which can be changed or manipulated in an experiment and for different values of the independent variables the value of the dependent variable can be find out. The dependent variable cannot be changes manually but instead the changes occur in the dependent variable is because of the changes that occur in the independent variable.

Therefore, depending upon the analytical ability of the scientists the conclusions are likely to be different. These predictions cannot be considered accurate as these are not testable they are mare predictions.

yes it is balanced

assuming that your periodic table has eighteen columns, you should highlight   the four elements in the third column from the left of the table.

neutral atoms of elements after calcium contain d electrons. the energy of d orbitals of a particular main shell lies between the energy of the s and p orbitals of the next main shell. for example, electrons in the have energy higher than those in the orbital while lower than those of the orbital.

by the aufbau principle, electrons fill orbitals one at a time, starting from those of the lowest energy. the orbital is therefore filled right after orbitals and before orbitals.  

potassium has electron configuration and calcium . the s orbital of a main shell holds a maximum of two electrons. the next element would thus have the electron configuration and satisfy the requirements.

a neutral atom of the element contains three electrons on top of the most recent noble gas element. it should thus be placed in the third column of the periodic table. both scandium and yttrium would satisfy the conditions. an aufbau diagram indicates that the 4f orbital is filled before the 5d. however, it appears that exceptions exists for both lanthanum and actinium. neutral atoms of the two d-block elements also demonstrate the and should be highlighted as well.
