Each line can have prepending and appending spaces as long as the two parts look correctly and the second part is indented at least one space more than the first one. You may have appending/prepending newlines and/or spaces. You may not use tabs for spacing (as long as there isn't an interpreter which replaces them correctly with spaces). Because of a mistake of mine, you can choose to use ______ _____ _____ _____ _____ _____ _____ _____ _____ _____ _____ _____ _____ _____ as the 1st line of the second part. Data: you can use this text as a reference (but not as input): Contents: symbol, atomic number, group, period groups 8 & 9 and periods 4-17 are used for the second part.
