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.
Unless 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.
Charge attraction is what causes ions to form to ionic bonds. This is learnt in science.

Is ionisation enthalpy of potassium higher than that of sodium?
The ionisation enthalpy of potassium is lower than that of sodium.
Is isotopes have same ionisation enthalpy?
yes, it is correct.
What is 1st ionisation enthalpy?
it is the energy required for a mole of atom to loose a mole of electron.
What is back ionisation?
Back ionization is a phenomenon in which ions formed in a mass spectrometer collide with neutral molecules and reintroduce electrons, causing the formation of additional ions. This can lead to interference and signal suppression in the mass spectrometry analysis.
Ionisation energy of noble gases?
Noble gases have high ionization energies due to their stable electron configurations and full outer electron shells. This makes it difficult to remove an electron from them compared to other elements. The ionization energy generally increases from helium to radon within the noble gas group due to increasing nuclear charge.
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.
How can you relate ionisation potential and ionisation energy?
Ionisation potential and ionisation energy are essentially the same concept - they both refer to the amount of energy required to remove an electron from an atom or molecule. The terms are often used interchangeably in practice.
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.
Who ionisation energy differs?
Ionisation energy differs between elements due to variations in the number of protons in their nucleus, which affects the strength of the attraction between the electrons and the nucleus. Elements with higher atomic numbers typically have higher ionisation energies due to increased nuclear charge. Additionally, ionisation energy generally increases across a period and decreases down a group on the periodic table.
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.
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.
Is isotopes have same ionisation enthalpy?
yes, it is correct.
