When the atom loses a balancing electron or gains an unbalancing electron.
For instance, there is one proton in hydrogen. To be electrically neutral (or balanced), there has to be one electron. If you magnetically strip the electron from hydrogen, you get an H+ ion which is electrically positive. If you force an electron into the hydrogen atom through centrifuges, etc, you have an H-. One electron has one - charge, and one proton has one + charge. The +'s must balance the -'s, otherwise you have an ion.

∙ 11y agoUnless the element is a noble gas, it does not have a full valence shell, and is unstable. In order to fix this, it either loses or gains electrons giving it a charge. For example, Sodium needs to lose 1 electron in order to be stable, so by losing it, it gains a positive charge. Or, compounds can go under ionisation, for example hydrochloric acid. When put in solution, the H and Cl atoms, separate from each other, and become H+ and Cl- ions.

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.
What is back ionisation?
Electrons which have not attached themselves to powder particles also travel in the air stream and along the electrostatic field lines to the item being coated. This is because it is grounded. The unattached electrons are attracted to the component together with the powder particles where they build up because of the isolating layer of the already deposited powder particles. If too many charges with the same polarity are deposited on the workpiece, the electrostatic force between the individual particles becomes so strong, that they repell each other and get pushed away from the surface. This is called back ionisation. Back ionisation causes discharges within the powder coat itself and also makes it difficult to coat complex shapes. Additionally, back ionisation causes the powder coat to be uneven and when stoved, the finished surface looks like orange peel.
Is isotopes have same ionisation enthalpy?
yes, it is correct.
Ionisation energy of noble gases?
noble gases have the maximum ionisation energy. helium has the highest ionisation energy
How does smoke affect ionisation?
Smoke alarms use ionisation of air by an alpha source. A small pellet of the isotope of Americium sets up a current of a few micro Amps across an air gap and this is monitored by the electronic circuit. When smoke enters the ionisation cell the current is reduced as the smoke particles neutralise the charged ions. The dip in current causes the alarm to sound.
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.
What are the side effects of radioactive tracers used for sentinel node biopsy?
toxicity the radiations are ionising radiations. they cause ionisation in the body and causes free radical formation.
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
