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
Why is the ionisation energy of Nitrogen higher than Beryllium?
Beryllium is a metal. It has 2 valance electrons (in the outer shell), and therefore it tends to lose those electrons in order to achieve a stable electron configuration, which in the case of beryllium is also 2 electrons, but in the inner shell. Nitrogen is a nonmetal, with 5 valence electrons, and it tends to acquire more electrons in order to reach a stable electron configuration of 8. Less energy is need to lose electrons when the result is going to be a stable electron configuration.
Why does bromine have higher ionization energy then lead?
Bromine has less valence shells than lead making the distance between its valence electron and its nucleus less than that of lead. This means that there is greater attraction between the nucleus and electron for bromine and it requires a higher ionisation energy to remove its electron.
Which atom has a lower ionization energy aluminium or boron?
The maximum capacity of electron accommodation in aluminium is 18 electrons( M shell) on contraty it has only 3 valence electrons whereas boron has maximum capacity of 8 electrons(L shell) and it has 3 valence electrons so electron population of Aluminium is less than that of boron.
How many protons does the second type of boron atom contain?
5. If it is more or less than 5 protons then it is not boron.
Why is the first ionization energy of boron lower than beryllium?
The rise in ionisation energy is not regular. To explain this we must remember that the second shell of electrons is actually subdivided into 2s and 2p. The most easily removed electron in Boron is that in the 2p orbital, higher in energy than the 2s electrons in Beryllium. It therefore needs less energy for total removal than does the 2s electron of Boron. This outweighs the effect of the increased nuclear charge of Boron, which tends to make its outer electron harder to remove.

Which element is more reactive lithium or beryllium?
Lithium is wayy more reactive... like, duh? An elements reactivity depends on its ionisation energy (the amount of energy required to remove one electron from the atom) and if you look at a periodic table the ionisation energy is known to increase across the table and decrease down it. Berylium is further across the table than lithium so you'd expect it to have a lower ionisation energy and be less reactive. This is because beryllium (atomic number 4) has 4 protons, which cause a positive charge and subsequent attraction of electrons, while lithium has the atomic number 3 and therefore only has 3 protons to attract its electrons. Lithium is a Group I alkali metal, while Beryllium is a Group II alkaline earth metal. Group I Alkali metals are generally more reactive as they only need to lose one electron to have a complete outer shell.
Why is the ionisation energy of Nitrogen higher than Beryllium?
Beryllium is a metal. It has 2 valance electrons (in the outer shell), and therefore it tends to lose those electrons in order to achieve a stable electron configuration, which in the case of beryllium is also 2 electrons, but in the inner shell.

Less energy is need to lose electrons when the result is going to be a stable electron configuration.
Elements with high ionisation energy have?
1.A small atomic/ionic radius 2.therefore less number of protons 3. more net nuclear attraction between the positively charged nucleus 4. higher energy is needed to break those bonds. 5. therefore an element has high ionisation energy
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
What is the pH OF beryllium oxide?
The PH of Beryllium Oxide is anything less than 6
Is the ionization energy of alkali metals larger or smaller than the alkaline earth metals in the same period?
It is about first ionization energy. It is less than alkaline earth metals.
Why does bromine have higher ionization energy then lead?
Bromine has less valence shells than lead making the distance between its valence electron and its nucleus less than that of lead. This means that there is greater attraction between the nucleus and electron for bromine and it requires a higher ionisation energy to remove its electron.

Why does carbon have a higher first ionization energy than boron?
this is simply by the energy needed for the outer electron of boron is less than the energy for carbons outer electron. most elements which change shell will have a sudden decrease which then the factor of extra shielding decreases the attraction of the electron and the center of the atom.
Does a boron atom have less protons than a lithium atom?
Boron has more protons. It has 5, lithium has 3.
