diagonal relationships are shown by elements in Periodic Table with same charge to radius ratio, i.e. same polarizing power. important examples are beryllium and magnesium, boron and aluminium, carbon and silicon. diagonal relationship leads to "mimicking" of chemical properties, i.e. beryllium will show properties of magnesium anomalous to its group behavior, for instance formation of nitrites. similarly, boron will "mimic" aluminium and show properties like formation of amphoteric oxides. also boric acid is not a protic acid as it gives H+ only in water, just like aluminium.(B(OH)3+ H2O=>B(OH)4-)
What else can I help you with?
What is the density of gallium if aluminium has a density of 2.70 gcm3 and Boron has a density of 2.08 gcm3?
The density of gallium is between 2.08 g/cm³ and 2.70 g/cm³ since gallium is located between boron and aluminum in the periodic table.
What are the similarities between aluminium and boron?
Both are members of the 13th group of the Periodic Table (boron group).
Which atom has a lower ionization energy aluminium or boron?
The maximum capacity of electron accommodation in aluminium is 18 electrons( M shell) on contraty it has only 3 valence electrons whereas boron has maximum capacity of 8 electrons(L shell) and it has 3 valence electrons so electron population of Aluminium is less than that of boron.
Why aluminium is less populated than boron?
Aluminum is less abundant than boron because boron has a higher atomic number and thus is more stable. Aluminium is more reactive and tends to form compounds with other elements rather than existing in its pure form. Boron also has more natural sources and is used in a variety of applications, contributing to its higher population.
What element family does the element Aluminium belong to?
The element Aluminium (Al) belongs to the Group 3 - Boron Family. This family includes: Boron (B) Aluminium (Al) Gallium (Ga) Indium (In) Thulium (Tl) (Ununtrium [Uut])* Every element in this group has three electrons in the outer shell of their atoms. The group is sometimes called "Earth Metals" *Ununtrium has been observed but not officially confirmed by the IUPAC.
What family is boron from?
Boron is from the 3A family, the same as Aluminium.
Which is a non metal gallium indium aluminium boron?
boron
What does the boron group contain?
Elements : Boron, Aluminium, Gallium, Indium, Thallium They are of Group 13.
Why does electropositivity first increase from boron to aluminium and then decrease down the group?
Boron is a metalloid, while aluminium is a metal. The size of the aluminium atom is much greater than boron, so electropositivity increases from boron to aluminium. But then electropositivity decreases from aluminium to thallium due to the poor shielding effect of the d10 orbital.
What is the density of gallium if aluminium has a density of 2.70 gcm3 and Boron has a density of 2.08 gcm3?
The density of gallium is between 2.08 g/cm³ and 2.70 g/cm³ since gallium is located between boron and aluminum in the periodic table.
What is the difference between sodium and aluminum'?
Sodium is a highly reactive alkali metal whereas aluminium is a less reactive metal in the boron group.
On the periodic table which chemical family is Aluminium located in?
Aluminium is located in the Group IIIA - the Boron family on the periodic table.
What are the similarities between aluminium and boron?
Both are members of the 13th group of the Periodic Table (boron group).
What is the most abundant metal in the earths crust and its a member of the boron family?
Aluminium
I am a member of the boron family and am the most abundent metal in the earths crust?
Aluminium.
What are the third element of the periodic table?
Boron, aluminium, gallium ,indium ,thallium
Which atom has a lower ionization energy aluminium or boron?
The maximum capacity of electron accommodation in aluminium is 18 electrons( M shell) on contraty it has only 3 valence electrons whereas boron has maximum capacity of 8 electrons(L shell) and it has 3 valence electrons so electron population of Aluminium is less than that of boron.
