What is the correct order of ionisation energy?
-That is why the correct order of ionisation energy is C
< O < N < F.
Which has more ionisation energy O or S?
The sulfur ion has an extra shell than an oxygen ion, so the atomic size of sulfur should be greater than oxygen. Therefore, the ionization energy of an oxygen ion should be more than a sulfur ion because the electrons in oxygen are closer to the nucleus when compared to sulfur.
Which of the following ionization energy order is incorrect?
The order O
Which of the following is correct order of density?
So, the order of density is down the group at first decreases then increases.
Why density of Be is more than MG?
Beryllium can be thought of as being even more covalent than magnesium. The small size (ca. 0.3 …) results in a very high charge density of Be2+. Both beryllium and aluminum form covalent compounds or strongly solvated cations, and both form polymeric hydrides, chlorides, and alkyls.
Is beryllium or magnesium 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.
Are Group 2 metals alkali?
The Group 2 alkaline earth metals include Beryllium, Magnesium, Calcium, Barium, Strontium and Radium and are soft, silver metals that are less metallic in character than the Group 1 Alkali Metals.
Why Be and Mg 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.
magnesium chloride is not impact colour to the flame.
Common elements
