Puzzle #1: Return Date (Hint: no dots, no dashes, just 3 digit return date) *
(PLEASE HELP ME WITH THIS ESCAPE ROOM)

The return date is 3 0 4

Explanation

In the letter, it is mentioned that the school will reopen after 29th of April. Thus, the tentative date of the school to reopen is 30th of April. The three digit return date is 3 0 4

3 0 4 because 30 is the date when the school will reopen and 4 is the month i.e., april when the school will reopen.

"among the transition metal elements, manganese and zinc have a slight lowering of electronegativities. the reason behind this is that the nuclear charges of these elements are slightly weaker than the other transition metal elements due to the way their valence electrons are filled up. both manganese and zinc have their valence electrons filled up to the 4th shell with 1 pair of electrons (4s2) completely occupying it. although the electrons in the 3rd shell (3d) are yet to be paired since the outer most shell is filled up, the ability of the nucleus to attract electrons is lessened. hence,   the electronegativity (or the ability to attract electrons) is lessened."
