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.

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.
What has two more protons than boron?
Carbon has two more protons than boron. Boron has 5 protons while carbon has 6 protons.
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.
Why is boron being treated for arthritis?
Boron is being studied for its potential role in reducing symptoms of arthritis due to its anti-inflammatory properties and its ability to support bone health. Research suggests that boron may help decrease inflammation and pain associated with arthritis, as well as improve joint function. However, more studies are needed to fully understand the mechanisms and effectiveness of boron in arthritis treatment.
Why boron is non metal?
THE STRONGER THE TENDENCY TO LOSE ELECTRONS,THE MORE ELECTROPOSITIVE AND MORE METALLIC AN ELEMENT IS.SINCE BORON IS VERY SMALL AND THE FORCE OF ATTRACTION BETWEEN THE NUCLEUS AND THE VALENCE ELECTRON IS VERY HIGH,AS WELL AS LARGE VALUE OF IONIZATION POTENTIAL INDICATES THAT BORON DOES NOT HAVE THE TENDENCY TO LOSE ELECTRONS THAT IS WHY IT IS LESS ELECTROPOSITIVE AND THEREFORE IT IS A NON-METAL
Is iodine -131 a more stable than barium -137?
Iodine 131 has a half-life of 8.0197 days. Barium has no half-life. So no, Iodine-131 is not more stable than barium-137.
