Its most likely that Boron would react in a similar way as Aluminium because both of them are in the same group (IIIA) - one above the other.But actually, Boron behaves more like Silicon.Because:
Boron is in very specific place in its period.This place is on the boundary between the metals (Li - Be) and nonmetals (C - Ne) which makes Boron a metalloid. Aluminium is in the next period, right under Boron (Their both are present in a common group).This place would give him more metal properties than Boron, so Aluminium turns out as one of the most common and widespread metals.Right next to Boron, Carbon is present.Carbon is in the nonmetal section of 2nd period, so its properties also would be different in contrast to these of Boron.But right under Carbon and right next to Aluminium, Silicon is present.Its nearer to the right side of the Periodic Table than Aluminium is, so its properties won't be namely metallic.But its also right under the typical nonmetal Carbon which would mean that its properties can't also be absolutely nonmetallic.This gives mixed properties to Silicon, making it a metalloid.Exactly like Boron.
That's why Boron reacts more like Silicon.
Aluminum, the element immediately under boron in its column on a wide form periodic table.
Element A and element B are the most likely to have similar properties because they belong in the same family, because if you know an element's family you can tell the number of valance electrons and the elements they react with. In periods, the properties are not alike, they slowly change in a pattern.
it is reffered to as the element's activity
it tells you what block it falls in,s,p,d,or f.
Sodium is a highly reactive element. It is unstable to exist on its own and will react whenever it is capable, which is very likely in nature.
You are correct. Boron Sulphide will even react with atompheric water so has to kept away from air.
in your question boron reacts to moron. boron cannot react by itself. it needs to react with another chemical.
Under normal circumstances boron does not react with water.

The boron family does not react to many items. However, the one group that it does react violently with is the halogen group.
Boron does not react with water or oxygen but when Boron burns it creates boron trioxide and when Boron burns in air when heated it creates a mixture of Boron trioxide and Boron Nitrate. Boron does not react with Acids or Alkalis and will only react if it is in a highly divided state. Also Boron is oxidised by Nitric Acid to produce Boric Acid and finally Boron reacts with fused Sodium Hydroxide to form Sodium, Borate and Hydrogen. Boron is also used in the bearings of wind turbines and in the nuclear industry for a moderator for neutrons.
Nobel gasses.
Francium is one such.
Crystalline/solid boron does not react at all with sulfuric acid. However, finely powered boron will react with sulfuric acid but very slowly.
what do they react to
Technetium react with oxygen, halogens, oxygen, sulfur, selenium, tellurium, boron, carbon etc. and can form alloys with metals.
Under favorable conditions, carbon and boron can react to form boron carbide.
