Today's puzzles are about helping Ukraine.
One of the world's most original and prolific puzzle creators is the Grabarchuk family. The family moved to the USA in 2013 after becoming renowned for their puzzle books, websites and apps. Donald Knuth says that Serhiy Grabarchuk, the father of the clan, has his vote as the world's current puzzle Laureate. His works are beautiful and useful.
The Grabarchuks have been publishing a daily puzzle that promotes Ukrainian culture in order to raise money.
The puzzles were selected from the archive. If you enjoy them, you should contribute to their suggested causes. Slava Ukraini!

Which digit should replace the question mark?

4. There is a box of fox.
All 8 equations, across and down, are all correct if you put a digit in each box. One box has a digit.
5. I would like you to sign mine.

One element has no letter in common with another element. Each answer is unique.
All the answers are known elements, words that are not in a Chemist's vocabulary.
There are noSPOILERS. I will be back at 5pm UK with the answers.
The Grabarchuk story began when Serhiy was a schoolboy. He turned his talent for making puzzles and magic tricks into a career. He and his wife had a small company publishing puzzle books, and now the business has expanded to websites and apps, with his sons, Serhiy Jr and Peter, and their wives, Kate and Helen. The family's most successful puzzle is called Strimko, a pencil and paper puzzle.
If you enjoyed the puzzles today, please donate to Ukraine. The National Bank of Ukraine has donation pages for humanitarian and military support.
