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.

How nature of orbitals affect ionization energy?
complexity of shapes of orbitals lead to increase in ionization energy. s orbital is spherical in shape, there is an equal tendency of finding an electron anywhere in the sphere so electron can easily be removed from gaseous atom. hence, ionization energy will be low. while in p orbitals dumb-bell shape provides a bit difficulty to occur electron everywhere with equal probability so it will lead to an increase in ionization energy.
Why is the first ionization energy of aluminum lower than the first ionization energy of gallium.if the increased proton no.is the case then why the i.enthalpy is increasing everywhere down the group?
It has something to do with the effective nuclear charge experienced by the valence electrons in Al and Ga. While aluminum's valence electrons are in the 3p shell, and there are 13 protons in the nucleus. Gallium's valence electrons are in the 4p shell, and there are 31 protons in the nucleus. Additionally, the atomic radius of gallium is not too much larger than that of aluminum. Thus, the electrons in gallium are pulled more strongly to the nucleus and they are more difficult to remove. A similar but lesser effect can also be seen in group IV/14, where Germanium has an almost identical first ionization energy to Silicon, and after the F shell is filled--thallium has a higher first ionization energy than Indium, and Lead has a higher first ionization energy than tin.

Does sodium or chlorine have a higher ionization energy?
The second ionization energy of sodium is so much greater than the first because the first electron is removed from the valence shell, while the second electron is removed from the core orbitals. Additionally, the sodium atom has a positive charge after the first ionization, which thus attracts the remaining electrons more strongly. Both of these factors lead to a much higher second ionization energy compared to the first.
What does lead plus bromine equal?
lead + bromine ---> lead bromide Pb + Br2 ---> PbBr2 As a chemical compound containing lead, it is categorised as probably carcinogenic to humans. It is a white powder at room temperature.
How is bromine transported?
bromine is commonly transported in steel tanks lined with lead often supported with strong metal frames. this prevents the risk of the chemical escaping in the risk of an accident. Lead is used as Bromine is capable of dissolving metals however it will nor corrode lead.
Ionic bonds what is lead plus bromine?
PbBr2 - Lead (II) Bromide
Which elements would you get when electricity is passed through molten lead bromide?
