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 does an increase in atomic radius lead to a lower ionization energy?
An increase in atomic radius leads to a lower ionization energy because the outermost electrons are farther away from the nucleus, which weakens the attraction between the electrons and the nucleus. This makes it easier to remove an electron, resulting in a lower ionization energy.
When lead and bromine combine what is it called?
When lead and bromine combine, they form lead(II) bromide.
What elements are in lead bromide?
Lead and bromine, Pb and Br
Is lead bromine an ionic bond?
Yes, lead bromine forms an ionic bond. Lead donates electrons to bromine, resulting in the formation of positively charged lead ions and negatively charged bromine ions, which are held together by electrostatic forces of attraction.
What is the order of increasing ionization between lead cesium and barium?
The order of increasing ionization energy among lead (Pb), barium (Ba), and cesium (Cs) is cesium < barium < lead. Cesium, being in Group 1, has the lowest ionization energy due to its larger atomic radius and lower effective nuclear charge. Barium, an alkaline earth metal, has a higher ionization energy than cesium but lower than lead, which is a post-transition metal with a higher effective nuclear charge and smaller atomic radius. Thus, the increasing order is Cs < Ba < Pb.
What has the largest first ionization energy Se Sb Pb Cl?
Among the elements listed, chlorine (Cl) has the largest first ionization energy. Ionization energy generally increases across a period from left to right on the periodic table, and since chlorine is located in Group 17 (the halogens) and is to the right of selenium (Se), antimony (Sb), and lead (Pb), it has a higher ionization energy than these elements. Selenium and antimony are both in the same group as chlorine but are lower down, while lead is in Group 14 and has a much lower ionization energy due to its position.
Which element has a higher first ionization energy than carbon?
Oxygen has a higher first ionization energy than carbon. This is because ionization energy increases across a period in the periodic table, and oxygen is located to the right of carbon in Group 16. As a result, oxygen's increased nuclear charge and smaller atomic radius lead to a stronger attraction between the nucleus and its electrons, requiring more energy to remove an electron.
What element has the largest first ionization energy Sb Se Cl or Pb?
Chlorine (Cl) has the largest first ionization energy among the elements listed (Sb, Se, Cl, and Pb). Ionization energy tends to increase across a period and decrease down a group in the periodic table. Since Cl is located in the second period and is further right compared to the others, it has a higher ionization energy than antimony (Sb), selenium (Se), and lead (Pb).

What element has the highest ionization energy in group 4 of the periodic table?
Carbon has the highest ionization energy in Group 4 of the periodic table. This is because as you move across a period from left to right, the ionization energy generally increases due to increase in effective nuclear charge. Among the elements in Group 4 (carbon, silicon, germanium, tin, lead), carbon has the highest ionization energy.
Why does an increase in atomic radius lead to a lower ionization energy?
An increase in atomic radius leads to a lower ionization energy because the outermost electrons are farther away from the nucleus, which weakens the attraction between the electrons and the nucleus. This makes it easier to remove an electron, resulting in a lower ionization energy.
What Identification Energy responsible different reaction rates?
Ionization energy, which is the energy required to remove an electron from an atom or ion, plays a significant role in determining reaction rates. Higher ionization energy typically indicates a more stable atom or ion, making it less likely to participate in reactions, while lower ionization energy can lead to increased reactivity. Additionally, activation energy, the energy needed to initiate a reaction, directly influences how quickly reactants can convert into products; reactions with lower activation energies tend to proceed faster. Overall, both ionization energy and activation energy are crucial in understanding the rates of chemical reactions.
When lead and bromine combine what is it called?
When lead and bromine combine, they form lead(II) bromide.
What elements are in lead bromide?
Lead and bromine, Pb and Br
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.
Is lead bromine an ionic bond?
Yes, lead bromine forms an ionic bond. Lead donates electrons to bromine, resulting in the formation of positively charged lead ions and negatively charged bromine ions, which are held together by electrostatic forces of attraction.
