Yes, barium has a lower ionization energy than calcium. This is because barium is located further down in Group 2 of the Periodic Table, meaning it has more electron shells and greater electron shielding. As a result, it requires less energy to remove the outermost electron compared to calcium, which is higher up in the group.
What else can I help you with?
Does calcium and barium have the same or different reactivites?
Calcium and barium have similar reactivities, as both are alkaline earth metals located in Group 2 of the periodic table. However, barium is generally more reactive than calcium due to its larger atomic size and lower ionization energy, which make it easier for barium to lose its outer electrons. Both metals react with water and acids, but barium's reactions tend to be more vigorous.
Between beryllium and barium which element will have the lower ionization energy?
Barium has more energy levels. So it has lesser ionization energy.
Why the second ionization energy of Ca is lower than the second ionization energy of k?
Because with the 2nd ionisation of K, you are trying to take an electron from a fully filled orbital (octet rule) whereas with calcium it is getting down to a fully filled orbital
Is ionisation enthalpy of potassium higher than that of sodium?
The ionisation enthalpy of potassium is lower than that of sodium.
Why boron has a lower first-ionization energy than beryllium?
Because in Boron there is a complete 2s orbital and the increased shielding of the 2s orbital reduces the ionisation energy compared to that seen in Beryllium.

Do calcium and barium have the same or different reactivities?
Barium is more reactive than calcium due to its lower ionization energy and larger atomic size, allowing it to easily lose electrons and react with other substances. The reactivity of an element depends on its position in the periodic table and its atomic structure.
Does calcium and barium have similar or different reactivities?
Calcium and barium have similar reactivities, because they are both alkaline earth metals. Quantitatively, barium is slightly more reactive than calcium because it has more electron shells between its valence electrons and its nucleus.
Is barium more reactive than calcium?
Yes, because it is lower down in the group.
Why the second ionization energy of Ca is lower than the second ionization energy of k?
Because with the 2nd ionisation of K, you are trying to take an electron from a fully filled orbital (octet rule) whereas with calcium it is getting down to a fully filled orbital

Explain the increase in pH on progressing from magnesium oxide to barium oxide?
On progression from magnesium oxide to barium oxide, the metal ion has an increasing atom size, with a decreasing ionisation energy and can easily lose one electron to form more the hydroxide ions (or in another point of view leads to lower activation energy and hence faster reaction) this is why there is an increase in pH.
Why ionisation energy of boron is lower than beryllium?
The ionization energy of boron is lower than beryllium because removing an electron from boron involves taking it out of the 2p orbital, which is higher in energy than the 1s orbital of beryllium. This makes it easier to remove an electron from the 2p orbital of boron, resulting in a lower ionization energy.
Why boron has a lower first-ionization energy than beryllium?
Because in Boron there is a complete 2s orbital and the increased shielding of the 2s orbital reduces the ionisation energy compared to that seen in Beryllium.
How does low ionisation energy favor the formation of ionic bond?
Ionisation energy is defined as the amount of energy required to remove the most loosley bound or valence electron from an atom. The lower the ionisation energy, the easier it is to remove the electron. Once the electron has been removed, electroneutrality is lost and the atom develops a positive charge and is known as a positively charged ion. Now, an ionic bond is the bond formed between two oppositely charged species. For example, a bond between a positively charges sodium ion and a negatively charged chloride ion. The lower the ionisation energy, the easier it will be for the atom to lose an electron, thereby forming a positively charged species which will be capable of forming an ionic bond with a negatively charged species. Or lower the ionisation energy, the greater is the tendency to form an ionic bond.
Why is barium more reactive with water than calcium?
Barium metal reacts with water to produce barium hydroxide and hydrogen gas, according to the following equation: Ba(s) + 2 H2O(l) -> Ba2+(aq) + 2 OH-(aq) + H2(g) Some metals react with dilute acids, such as sulfuric acid, produsing a salt solution and hydrogen gas. However, if barium metal is added to water a layer of insolube barium sulfate forms at the surface, according to the equation: Ba2+(aq) + SO42-(aq) -> BaSO4(s) As an aside, calcium behaves in a similar manner. If you don;t have ready access to calcium metal, then this can be observed by placing an egg into quite dilute solutions of hydrochloric and sulfuric acids. In hydrochloric acid, the egg shell (mostly calcium carbonate) is removed. However, in sulfuric acid the reactions does not proceed due to the formation of insoluble calcium sulfate at the surface of the egg shell.
