It is not ionic, it is covalent.
Potassium and fluorine will form an ionic bond
Yes, they form an ionic bond.
Yes
No, they are both halogens and nonmetals with a electronegativity too close together to form an ionic bond. They, if ever bonded, would form a covalent, or polar covalent bond.
ionic bonds
fluorine iodine would be molecular because it is 2 non metals.
Potassium and fluorine will form an ionic bond
All of the metallic elements will form an ionic bond with fluorine.
Yes, they form an ionic bond.
Magnesium and iodine react to form the ionic compound magnesium iodide - MgI2.
Ionic
Mg2F
Yes
No, they are both halogens and nonmetals with a electronegativity too close together to form an ionic bond. They, if ever bonded, would form a covalent, or polar covalent bond.
It is ionic bond
ionic bonds
Ionic bond, as the difference in electronegativity between calcium and fluorine is over 1.7
