science - periodic table
posted by manny .
Some elements are missing, and others have no name but have an atomic number. (116) When will the table ever be complete? How do we know that it's not already complete?
sorry start the sentence
On the periodic table....
The table will be complete when scientists stop making new elements. It is complete now for elements that occur naturally
An arrangment of elements in columns based on a set of properties that repeat from row to row... is hat?
