Krf2 shape.

The name Krypton is derived from the Greek word "kryptos", meaning "hidden". However, the inert quality of these gases was disproved when Xenon compounds were created in 1962 and a Krypton compound (KrF2) was synthesized successfully a year later. This proved that this group of gases is not necessarily inert.0 2. ion reaches the detector in 4.654. . 4. s. In the TOF mass spectrometer, a germanium × 10. –6.
