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 happens to the first ionisation energy of the elements as a period is crossed?

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.
Are noble gases outer energy levels to full to combine with other elements?
Yes they have full energy levels,this makes them stable.They are highly unreactive, to add on that ionisation is very high in noble gases.
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.
What is the relationship between ionization energy and the alkali metals?
There is no relation ship. They have the lowest ionization energies.
Why do cations form?
metals have high electropositivity and low ionisation energy. So they tend to form cations easily.
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.
What is ionisation energy What is first ionisation energy?
The first ionization energy of an atom or molecule describes the amount of energy required to remove an electron from the atom or molecule in the gaseous state.
Which has high ionisation energy lithium or lithium plus?
lithium plus. removing electron from something that is positive is much harder.
Why do metals form cation?
metals have high electropositivity and low ionisation energy. So they tend to form cations easily.
What are the properties of elements that vary periodically with the atomic number?
The properties like electronegativity , ionisation energy , enthalpy changes vary periodically with atomic number.
