MEASUREMENT Naming components of the scientific method In the table below you will find three descriptions of scientists engaging in activities that are part of the scientific method What are the missing words? description missing word? Dmitri discovers that the known chemica elements can be arranged in pattern of columns and rows_ with elements in the same column behaving similarly. But there is no element at certain place in the pattern and Dmitri proposes the that an unknown ement fits into that spot _ and that it will have properties similar to the elements above and below it in the pattern John sets up an in which he reacts measured amount of carbon with various measured amounts of oxygen_ and takes note of whether compound forms and weighs how much of each lement is consumed forming it Wolfgang develops about the arrangement of elements in the Periodic Table_ based on some ideas about how ectrons are arranged in the different atoms of different elements_ Using equations he develops, he is able to predict the exact arrangement of electrons in many atoms and from there predict why they are where they are in the Periodic Table.
