The first ionization potential of Boron is 800 kJ/mol, Barium is 502.9 J/mol
The essential difference is that in boron the electron being removed is in a 2p orbital in Barium it is in a 6s orbital. A rationalization is that the 6s electron is on average further away from the core, is better shielded than in B.

What elements can combine with the element boron?
Many elements can combine with Boron although not many compound with Boron in are found on Earth naturally. Here are some more common examples: Barium (Ba) - Forms Barium Borate Calcium (Ca) - Forms Calcium Borate Lithium (Li) - Forms Lithium Borate
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.
Is boron-10 or boron-11 more abundant?
Boron-11 is more abundant in nature compared to boron-10. Boron-11 accounts for approximately 80% of natural boron, whereas boron-10 makes up the remaining 20%.
Is boron-11 more abundant than boron-10?
Yes, boron-10 is more abundant than boron-11. Boron-10 makes up about 19.9% of natural boron, while boron-11 makes up about 80.1%.
What has two more protons than boron?
Carbon has two more protons than boron. Boron has 5 protons while carbon has 6 protons.

Does barium has lower ionisation energy than calcium?
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 is negative ionisation?
Negative ionisation is usually the result, in ionic bonding, of adding one or more electrons to an atom, molecule or even an negative ion. The last of these goes more negative.
Is barium a metalloid?
Metalloid. It touches the metalloid "staircase" on the periodic table. Yes, Boron is a metalloid, intermediate between metals and non-metals. It exists in many polymorphs (different crystal lattice structures), some more metallic than others. Metallic boron is extremely hard and has a very high melting point.
When evaluating the reactants BaO Mg one needs to determine uf magnesium is more active than?
When evaluating the reactants barium oxide (BaO) and magnesium (Mg), one needs to determine if magnesium is more active than barium. Magnesium is indeed more active than barium in terms of reactivity, as it is higher on the reactivity series. This means magnesium can displace barium from its compounds, allowing for potential reactions between the two substances. Therefore, the comparison focuses on magnesium's ability to react with other elements and compounds compared to barium's reactivity.
What has two more protons than boron?
Carbon has two more protons than boron. Boron has 5 protons while carbon has 6 protons.
Why is -11 boron more abundant than -10 boron?
Boron-11 is more abundant than boron-10 primarily due to its greater nuclear stability. Boron-11 has a more favorable neutron-to-proton ratio, which contributes to its stability and lower likelihood of radioactive decay. Additionally, the processes in stellar nucleosynthesis favor the production of boron-11 over boron-10, leading to its higher natural abundance.
Which is Sparingly soluble- barium chloride or barium sulfate?
Barium sulfate is sparingly soluble in water, while barium chloride is more soluble. Barium sulfate has a solubility of about 0.0015 g/100 mL of water at room temperature, while barium chloride is much more soluble at about 36 g/100 mL of water at room temperature.
Which is more reactive barium or cesium?
Cesium is more reactive than barium. Cesium is located lower down in Group 1 of the periodic table, making it more reactive than barium, which is further up the group. Cesium readily reacts with air and water, while barium is less reactive in comparison.
