Difference Between Beryllium and Aluminium

Beryllium and Aluminium are two metallic elements in two different periods and groups of the periodic table. The key difference between Beryllium and Aluminium is that Beryllium is a molecule in the group II (atomic number = 4) whereas Aluminium is a group XIII element (atomic number = 13).

How is beryllium similar to aluminum?

Beryllium shows resemblance with its diagonally opposite element aluminium. Points of similarity are: ... 3) These two elements have same electronegativity and the polarising power i.e. charge/ radius ratio of their ions are very similar.

Which is more metallic beryllium or Aluminium?

Your friends are correct. Be is more metallic than Al. The standard reduction potential for Be is -1.85 V while that of aluminium is -1.66 V.

What is the difference between beryllium and magnesium?

Beryllium can be thought of as being even more covalent than magnesium. The small size (ca. 0.3 Å) results in a very high charge density of Be²⁺. In addition, the ionization energy for beryllium is a large positive value (1^st ionization energy = 899.5 kJ/mol, 2^nd ionization energy = 14,848.7 kJ/mol).

Which of the following is not a similarity of beryllium with Aluminium?

But, the stability of Carbonate of Be is not similar to carbonate of Al. Hence, option C is the correct answer.

Which is more electropositive than Aluminium?

In the modern periodic table, alkali metals are highly electropositive elements. Caesium is the most electropositive element in the modern periodic table. Group 13 elements include boron, aluminium, gallium, indium and thallium. ... Hence, boron is less electropositive than aluminium.

Which is more metallic sodium or Aluminium?

Metallic character decreases as move from left to right in the periodic table, therefore sodium will be more metallic as compared to aluminum.

Which is more metallic B or C?

In a period, the non-metallic character increases from left to right Thus, among B,C,N and F, non-metallic character decreases in order:F>N>C>B. However, within a group, non-metallic character decreses from top to bottom, Thus , C is more non-metallic than Si.

Is magnesium or beryllium more reactive?

The alkaline-earth metals tend to lose two electrons to form M ²⁺ ions (Be²⁺, Mg²⁺, Ca²⁺, and so on). These metals are less reactive than the neighboring alkali metal. ... Magnesium is more active than beryllium; calcium is more active than magnesium; and so on.

What do beryllium magnesium and calcium all have in common?

Beryllium, Calcium and Magnesium are three of the six elements that fall into this category. The outer electronic structure of all these elements is similar due to which they all have similarity in their chemical and physical properties. They are all shiny, though fairly soft but still harder than alkali metals.

Why beryllium and magnesium do not give Colour to flame?

* The electrons in beryllium and magnesium are too strongly bound to get excited by flame. ... Beryllium and magnesium also belong to alkaline earth elements. Due to their small size it shows high nuclear effective energy. Due to this they beryllium and magnesium do not give color to flame.
