Build a Periodic Table Database

Backend Development
1

I cannot get ‘PASS’ for these two requirements:

  • You should add the element with atomic number 9 to your database. Its name is Fluorine, symbol is F, mass is 18.998, melting point is -220, boiling point is -188.1, and it’s a nonmetal

  • You should add the element with atomic number 10 to your database. Its name is Neon, symbol is Ne, mass is 20.18, melting point is -248.6, boiling point is -246.1, and it’s a nonmetal

However, I have successfully added them into the database:

I have seen repeated posts for this bug. And I have tried their workarounds to changing the data types into ‘VARCHAR’ or ‘DECIMAL’.
But it still doesn’t work.

Does anyone still encounter the same issues?

Welcome to the forum @as_if_my_last

Are there other data types you could use?

I changed the category from freeCodeCamp Support to Backend Development.

Happy coding
