How is krypton gas made?
krypton (symbol Kr) Gaseous nonmetallic element that is a noble gas. Discovered in 1898, krypton makes up about 0.0001% of the Earth’s atmosphere by volume and is obtained by the fractional distillation of liquid air. It is used in fluorescent lamps, lasers and in electronic heart valves.
What is krypton 81m?
Krypton-81m, an inert, radioactive gas with a physical half-life of 13 seconds was used to evaluate regional lung ventilation in 25 pediatric patients. This inert gas, with its 13-second half-life and 190-KeV-gamma emission, is ideally suited for imaging with present scintillation cameras.
What is the noble gas configuration for carbon?

Carbon/Electron configuration
How do you write the noble-gas electron configuration for carbon?
How do you write the noble-gas electron configuration for carbon? [H e]2s22p2 ……. For carbon Z = 6, and if there are 6 positively charge nuclear particles, there must be 6 negatively charged extra-nuclear particles in the neutral atom.
What is the symbol for carbon in the periodic table?
Carbon – Periodic Table Element Carbon Atomic Number 6 Symbol C Element Category Non Metal Phase at STP Solid
What is the number of electrons in a neutral atom of carbon?
Therefore, there are various non-equivalent definitions of atomic radius. The number of electrons in an electrically-neutral atom is the same as the number of protons in the nucleus. Therefore, the number of electrons in neutral atom of Carbon is 6.
What is the electron affinity of carbon in kJ mol?
Electron affinity of Carbon is 153.9 kJ/mol. In chemistry and atomic physics, the electron affinity of an atom or molecule is defined as: the change in energy (in kJ/mole) of a neutral atom or molecule (in the gaseous phase) when an electron is added to the atom to form a negative ion.
