what is ionisation?

Answer 1

Ionization is the physical process of converting an atom or molecule into an ion by changing the difference between the number of protons and electrons. This process works slightly differently depending on whether an ion with a positive or a negative electric charge is being produced. A positive electric charge is produced when an electron bound to an atom or molecule absorbs enough energy from an external source to escape from the electric potential barrier that originally confined it. The amount of energy required being equal to the Ionization potential. A negative electric charge is produced when a free electron collides with an atom and is subsequently caught inside the electric potential barrier, releasing any excess energy.

Ionization can generally be broken down into two types: Sequential Ionization and Non-Sequential Ionization. In classical physics, only Sequential Ionization can take place and therefore refer to the Classical Ionization section for more information. Non-Sequential Ionization violates several laws of classical physics and thus will be discussed in more detail in the Quantum Ionization section.

Answer 2

An ion is an atom or group of atoms that has lost or gained one or more electrons. An atom which has lost electrons acquires a positive charge and is known as a cation; an atom which has gained electrons has a negative charge and is called an anion. The process is called ionisation.

Answer 3

Ionisation is the process in which the electrons are seperated from the nucleus & hence the atom acquires the positive charge,that is ions are formed,so it is called ionisation .
There are different process to do ionisation

Answer 4

Ionization is physically being able to change an atom, or molecule, into an ion by changing the difference between the protons and electrons. Based on the Ionization potential, a negative or positive electric charge can be produced by colliding a free elctron into an atom with enough force to get caught into its electric potential barrier or by freeing an electron from the barrier utilizing an external source.

Answer 5

the removal of a valence electron from an atom, such that the atom gains a positive charge (or loses a negative charge whichever way you see it).

OR

the addition of an electron into the valence shell of an atom such that the atom gains a negative charge/loses a positive charge.

the electron is not removed from the nucleus, as preposterous as the first answerer said.

in thermochemistry, ionisation energy refers to the energy required in electron removal (to form cations), electron affinity referes to the energy required/released in electron capture (to form anions). in general chemistry, the term ionisation is simply the formation of ions from neutral atoms due to electron transfer.

Answer 6

I am answering this question shortly,
Ionisation is a process in which Ionic compounds dissolves in water and disassociate into their ions

Answer 7

you imagine an atom. it has a nucleus containing protons and neutrons surrounded by electrons. an atom is called neutral when the amount of electrons is same with the protons. that mean that the atom has no positive or negative charge.
when certain energy such as light energy radiates the atom, it will supply the electron with excess energy, making the electron has the ability to escaped from the atom. when this happen, the amount of electron will be reduced and the atom is not nuetral anymore. because it loses electron (electron is a negative), thus the atom become an ion (positive ion because amout of positive charge that is proton exceeding negative charge that is electron). that why it is called ionization

Answer 9

Ionization is the process of electrons being added or removed from an atom, so as to form an ion. It often refers specifically to the addition of electrons (as in "ionization energy"), although this is not always the case.

Answer 10

When an electron is plus or minus it's normal number of electons minus negative ion plus positive electron
