Want this question answered?
An ionic bond is formed when a metal and a non-metal react. Electrons are transferred during this process. Magnesium is a metal and Fluorine is not. So, it forms an ionic bond. I don't believe there is such thing as a diatomic bond, only diatomic molecules which are 2 atoms of an element (O2, N2, etc) Metallic bonds are formed between metals. And in covalent compounds the atoms share the valence electrons.
Electrons
An ionic bond forms when electrons are transferred between atoms.
When electrons are transferred between two atoms a covalent bond is formed is known as an ionic bond.
Ionic
It is ionic. Electrons are transferred from magnesium to oxygen.

They are more strongly attracted to the fluorine. We say that fluorine is more electronegative than hydrogen.
When electrons are transferred in a reaction, it is referred to oxidation/reduction or redox.
Ionic
HF is molecular (aka covalent) because it is a bond between two nonmetals in which electrons are shared. In the HF bond, Fluorine has six valence electrons and shares two electrons with Hydrogen. Hydrogen only has these two electrons because it only has a max of two electrons on its outer valence shell. Fluorine has an electronegativity of 4.0 (the highest on the Periodic Table), which is greater than Hydrogen's 2.2, so therefore Fluorine would be considered slightly negative in the bond, and Hydrogen would be slightly positive.It is not ionic because in an ionic bond, electrons are not shared, they are transferred.
No they do not, electrons are transferred between atoms
Two electrons are transferred between calcium and oxygen to form calcium oxide.
Magnesium fluoride, MgF2 is held together by ionic bonding between the positively charged magnesium ion and the negatively charged fluoride ions.
