Fluorescent lamps are your commonest household application of ionization, where the gas in the lamp is ionized to give out ultraviolet rays, which then excite phosphors on the inner surface of the tube to emit light.
X-rays are used commonly, and these because of their penetrating properties, will produce images of tissue. Unfortunately, these produce ionizing radiation as a byproduct of their operation, and too many x-rays are not good for you.

Why the first ionisation energy of O is less than that of N?
oxygen is more electronegative and so it wants the electron more than N
Is Aluminum chloride a strong or weak electrolyte?
AlCl3 is a strong electrolyte when dissolved in water it gives complete ionisation: Al3+ + 3 Cl-
Is fluorine ionization energy high medium or low?
first Ionisation energy is 1681 kJ/mol = 402.15 Kcal/mol it is high because of the F electron configuration will be 1s22s22p5
How is water softened without salt or potassium?
By de-ionisation of water, taking calcium and mgnesium ions out (ion exchange, hyperfiltration or reversed osmosis). Destillation is another (more expesive) method.
Does metallic bonding occur between atoms of copper or chlorine?
Metallic bonding occurs between copper atoms. Only copper is a metal and has the characteristics needed for metallic bonding. Metallic bonding occurs between atoms with low electronegativities (low tendency to attract electrons from other atoms) and low ionisation energies (little energy required to remove electrons from the atoms). The low tendency for the metallic atoms to keep their electrons allow their electrons to be shared between the atoms, which thus become cations. The cations tend to be very closely-packed; they are not repulsed by their similar positive charges, but attracted to the electrons flowing freely between the cations. Metallic bonding therefore occurs between copper atoms, which have low electronegativity and ionisation energy. Chlorine atoms have some of the highest electronegativity and ionisation energy of all elements, and thus do not exhibit metallic bonding.
Ionisation energy of noble gases?
noble gases have the maximum ionisation energy. helium has the highest ionisation energy
Why are the ionisation energy of isotopes the same?
no the same,first ionisation contains a slightly differences in isotopes
Is ionisation enthalpy of potassium higher than that of sodium?
The ionisation enthalpy of potassium is lower than that of sodium.
How does the ionisation energy change down the groups in the periodic table?
Ionisation energy decreases down the group. It is easy to remove an electron.
Is the degree of ionisation affected by dilution?
Yes
Is the ionisation energy of sodium same as chlorine?
No
What is better chlorine or ionisation system?
ionisation system stay in water whereas chlorine evaporate into the air, Chlorine irritates the skin, the eyes, and the respiratory system.
Why the first ionisation energy of potassium is only a little less than the ionisation energy of sodium?
both are in the same period which accounts for closeness. they are nonetheless different because there are more protons in the nucleus which means electrons are brought closer to it so there is a higher ionisation energy or potential
When does ionisation energy increases?
when we go from left to right
What rhymes with nitrification?
ionisation (anything with tion at the end)
Do gasses have to be hot for ionisation to take place?
Yes.
Does a gas have to be hot for ionisation to take place?
Yes.
