Respuesta :
Magnesium metal is easily deformed by an applied force, whereas magnesium fluoride is shattered. This is because magnesium atoms are held by covalent bond where as Magnesium fluoride form ionic compound.
By applying a force to an ionic compound due to which like charged ions which are located next to each other will cause which is the part of the compound to break off. The like charged ions in the compound repel each other, making the compound to break at that point.
What is alkaline earth metal?
The alkaline earth metals are those elements which correspond to group 2 of the modern periodic table.
All elements of this group forms a cation of +2 charge.
The other elements of this group are:
Beryllium, Magnesium, Calcium, Strontium, Barium, and Radium.
What is Halogen?
The Halogen elements are present in group 17 of the modern periodic table.
All elements of this groups forms anions of -1 charge.
The elements of this group are:
Fluorine, Chlorine, bromine, iodine, and astatine.
Thus, we concluded that the because of the formation of covalent bond in magnesium atoms where as ionic bond in Magnesium fluoride. They are different.
