CFC contains carbon, hydrogen, chlorine or fluorine.
Rb
Compounds of Na, Cs, Rb, Cs, Sr, Li, Ba, Ca, K are used in fireworks; also elements in pure form as C, Fe, Ti, Al.
These six elements are Li, Na, K, Rb, Cs and Fr.
Of the elements listed by atomic symbol, Cs has the largest atoms.
Californium applications - neutron source to start-up nuclear reactors (Cf-252) - neutron source for neutron diffraction instruments (Cf-252) - neutron source for neutron spectroscopy instruments (Cf-252) - raw material for the preparation of heavier chemical elements (Cf-249) - source for portable neutron activation instruments (Cf-252) - source for radiation therapy with neutrons (Cf-252) - source for neutron radiography (Cf-252) - source for moisture detectors (Cf-252) - source for gold and silver detectors (Cf-252) - source for analysis instruments of coals, cements etc. (Cf-252)

Californium (Cf).
Rb
The most valuable element is Californium (Cf). Its Cf-252 isotope is used in nuclear reactors and cancer therapy. Cf-252 costs $350 billion per pound
Compounds of Na, Cs, Rb, Cs, Sr, Li, Ba, Ca, K are used in fireworks; also elements in pure form as C, Fe, Ti, Al.
CFC's are stable enough. But when they come in contact with UV, they decompose and deplete ozone.
Two elements...Three Caesium atoms and two Nitrogen atoms
Cs (Caesium) is the most reactive!!!!
This is the geoup of alkali metals: Li, Na, K, Rb, Cs, Fr.
These six elements are Li, Na, K, Rb, Cs and Fr.
Today all elements up to atomic number 98 (including Cf) are considered as natural chemical elements.
