No, ionisation energies change depending on which element you look at and which ionisation (i.e. 1st, 2nd, 3rd...) you are taking about.
For example, as you go across period 3, the 1st ionisation energy generally increases.
- sodium (Na) has the lowest I.E.* as it has the lowest nuclear charge *[actual value is 494 KJ/mol ]
- magnesium (Mg) has a higher I.E.* than sodium as it has a higher nuclear charge *[actual value 736KJ/mol]
- Aluminium drops* below Mg but still higher than Na, this is because although the nuclear charge is greater the 1st electron is being taken from the 3P orbital as opposed to the 3S orbital. This means that the electrons distance from the nucleus is further (so lower attraction). *[actual value 577KJ/mol]
The trend increases from there except from Si to Cl [1060 to 1000KJ/mol], but I think you get the idea.
The I.E. is dependant on
1. Shielding
2. Distance from the nucleus
3. Nuclear charge

Which element in the fifth period has the highest ionization energy?
The element in the fifth period with the highest ionization energy is xenon. Ionization energy generally increases across a period from left to right, so xenon, being on the far right of the period, has the highest ionization energy.
What is the general trend of ionization energy as you go across the periodic table?
Across a period, first ionization energy increases. However, when going down a group, first ionization energy generally decreases. As you go down a group, atoms hove more total electrons so they don't really care that much about their outermost ones.
Does arsenic have the highest ionization energy?
No, arsenic does not have the highest ionization energy. Ionization energy generally increases as you move across a period in the periodic table from left to right. In the case of arsenic, it is found in the 3rd period, so elements to the right of it, such as bromine, have higher ionization energies.
Does Sulfur has a lower ionization energy than chlorine?
No, sulfur has a higher ionization energy than chlorine. Ionization energy is the energy required to remove an electron from an atom, and it generally increases across a period from left to right. Chlorine, being to the right of sulfur in the periodic table, has a higher ionization energy.
How can you determine whether ionization energy is a periodic function of atomic number?
Ionization energy is a periodic function of atomic number because it follows periodic trends in the periodic table. As you move across a period from left to right, ionization energy generally increases due to increasing nuclear charge. Similarly, as you move down a group, ionization energy generally decreases due to increasing atomic size. These trends repeat as you move through each period, making ionization energy a periodic function of atomic number.
Does K or Zn have lower ionization energy?
Potassium (K) would have a lower ionization energy compared to Zinc (Zn). This is because the ionization energy generally increases as you move across a period in the periodic table. Since Potassium is located further to the left in the same period as Zinc, it would have a lower ionization energy.
How does the first ionization energy change going down and across the periodic table?
As you move down a group on the periodic table, the first ionization energy generally decreases due to the increasing atomic size and shielding effect of inner electrons. Across a period, the first ionization energy generally increases because the effective nuclear charge increases, making it harder to remove an electron.
What is the trend in ionization energy of period 3 elements on the periodic table?
The trend in ionization energy of period 3 elements on the periodic table generally increases from left to right.
What is the energy needed to remove electrons from an atom called?
ionization potential energy. but remember the atom must be neutral .
What is the relationship between the xenon ionization energy and its chemical properties?
The xenon ionization energy is the amount of energy needed to remove an electron from a xenon atom. Higher ionization energy generally leads to lower reactivity, as it becomes more difficult to remove electrons and form chemical bonds. Therefore, xenon with high ionization energy tends to be less reactive and more stable chemically.
Is the pattern in ionization energy always true or generally true?
The pattern in ionization energy is generally true, but there can be exceptions due to factors such as electron-electron repulsions or orbital hybridization. In most cases, ionization energy tends to increase across a period and decrease down a group on the periodic table.
Is fire an ionization energy?
No fire is not an ionization energy
