Q.
Number of electrons surrounding $Kr \, in \, KrF_2 \, is$
Chemical Bonding and Molecular Structure
Solution:
Krypton (Kr) forms two covalent bonds with two fluorine atoms (one with each fluorine). Number of electrons in valence shell of Kr = 8 .Number of electrons its shares with two F-atoms = 2 $\therefore \, $ Total number of eiectrons found around Kr in KrF =8+2=10
