CFC contains carbon, hydrogen, chlorine or fluorine.
Of the elements listed by atomic symbol, Cs has the largest atoms.
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 these options the correct answer is e) Cs for cesium. If you checked it for Study Island then the answer is Francium (Fr)
Of the elements listed by atomic symbol, Cs has the largest atoms.
· Cadmium (Cd) · Caesium (Ce) · Californium (Cf) · Carbon (C) · Calcium (Ca) · Cesium (Cs) · Chlorine (Cl) · Chromium (Cr) · Cobalt (Co) · Copper (Cu) · Curium (CM)
Californium (Cf).
*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)
These elements are: K, Rb, Cs, Fr, Ra.
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.
Today all elements up to atomic number 98 (including Cf) are considered as natural chemical elements.
CsO2 is made of cesium (Cs) and oxygen (O)
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
Cs (Caesium) is the most reactive!!!!
These six elements are Li, Na, K, Rb, Cs and Fr.
