The equation for first ionization energy is the equation for the energy required to remove an electron from one mole of gaseous atoms to produce a mole of gaseous ions. It is as follows: X(g) ---> X^+1(g) + e^-1.

Why does helium has a higher first ionization energy than argon?
The ionisation energy depends on the orbital from which the electron is removed and also the distance of the orbital from the nucleus. In the case of Helium, the electron is removed from 1s orbital whereas in the case of argon it is from 3p orbital. As 1s is closer to the nucleus, the force of attraction experience by these electrons is higher and hence helium will have higher 1st ionisation energy.
Why second ionisation energy is larger than the first ionisation energy?
The reason the second ionization energy is higher than the first relates to the attraction between the electrons and the nucleus. When one electron is removed from an atom, the neutral atom becomes positive. When one attempts to remove a second electron from a positive ion, there is more attraction between the electrons and the nucleus due to the extra proton. Thus, the second electron is harder to remove and the ionization requires more energy.
How is Einstein's equation important to the Big Bang Theory?
Einstein's equation demonstrated that some of the energy released when the universe began was quickly turned into matter, the first matter in the universe.
What is the first law of thermodynamics known as?
The first law is also known as law of conservation of energy. It say that the energy can neither be created nor be destroyed but can only be transferred. Its is given by this equation dQ = dU + dW .
What is the best interpretation of the first law of thermodynamics?
The first law of thermodynamics says that energy can neither be created nor destroyed; it can only be changed from one form to another. One of the implications of this is that the total energy of the universe is finite. Einstein's famous equation E=mc**2 provides a corollary to the first law by demonstrating that mass and energy are interrelated. Since they are related by his equation, the first law could be modified to say that the combination of mass and energy is finite for the universe, or that matter is just another form of energy. When energy is converted to mass the increase in mass is usually so tiny that it is not detectable within experimental uncertainty but it can be calculated. The one exception to this is when high energy photons (e.g. gamma rays) convert to a matter-antimatter particle pair. However the antimatter particle so rapidly collides with a matter particle, converting back to a high energy photon that although easily detectable in experiments it has no practical value.

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.
First ionisation energy?
the first ionisation energy is the energy required to remove the first most loosely bound elecctron from a neutral gaseous atom in its ground state.
Why are the ionisation energy of isotopes the same?
no the same,first ionisation contains a slightly differences in isotopes
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
What happens to the first ionisation energy of the elements as a period is crossed?
tinger tinger tales
Which Lewis structure represent an atom x in period 4 with the highest first ionisation energy?

Why is the first ionisation energy of strontium larger than the first ionisation energy of rubidium?
Because, as we know that when we go across the period of the periodic table, the number of shells remain the same but the number of electrons and protons increases. So, Rb having its atomic number as 37 and Sr as 38, Strontium has got more nuclear charge as well as more electrons. As a result the first ionisation energy required to remove one electron is more in Strontium than Rubidium.
What are the ionisation enthalpies of potassium and sodium?
First ionization energy of sodium is 495,8 kJ/mol.First ionization energy of potassium is 418,8 kJ/mol.
What is meant by the first ionisation energy of nitrogen?
THis is the energy required to remove(ionise) one (the first) outer most electron. For nitrogen this would be quite a large figure, because nitrogen, wants to accept electrons ,rather than remove electrons. As a general rule as you go along any given period, the ionisation energies increase. There are two 'humps', with a slight fall in ionisation energiers in this general increase.
What is the first ionization energy for sodium?
Na(g) --> Na+(g) + e- First ionisation energy is always: X(g) --> X+(g) + e- with X being an element
What is the relationship between ionization energy and the alkali metals?
There is no relation ship. They have the lowest ionization energies.
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
