Ionic
Yes, a covalent bond exists between the magnesium atom and the fluorine atoms in MgF2. Magnesium forms a +2 cation and each fluorine forms a -1 anion, resulting in a ionic compound with covalent character due to the sharing of electron density between the atoms.
Magnesium chloride consists of ionic bonds.
In the formation of the binary ionic compound between fluorine and lithium, a lithium atom donates one electron to a fluorine atom. This electron transfer results in the formation of lithium cation (Li+) and fluorine anion (F-). The attraction between the oppositely charged ions leads to the formation of the ionic compound lithium fluoride (LiF).
The fluoride atom has 7 electrons in its outer shell (9 in total) but the ion of fluorine has any number of electrons in the outer shell. eg. F+ = the normal fluorine atom but with one less electron.
One electron is lost when a lithium atom forms a compound with fluorine atoms, as lithium has 1 valence electron and fluorine can gain one electron to achieve a full outer shell.

A fluorine atom forms a covalent bond with another fluorine atom to produce the fluorine molecule which is gaseous at room temperature.

Magnesium atoms lose 2 electrons to form a Mg2+ ion, and fluorine atoms gain 1 electron to form a F- ion. One magnesium ion forms an electrostatic attraction with two fluoride ions. This electrostatic attraction is an ionic bond. The resulting ionic compound is MgF2. Mg2+ + 2F- ---> MgF2

When fluorine reacts with a metal, it gains an electron to form the fluoride ion (F-). This process is called reduction, as the fluorine atom is gaining electrons.
There are 3 atoms in one molecule of MgF2: one magnesium atom and two fluorine atoms.
The simplest formula for the compound formed between boron and fluorine would be BF3, which is boron trifluoride. Boron typically forms compounds by sharing 3 electrons with each fluorine atom, resulting in a molecule with a boron atom at the center and three fluorine atoms surrounding it.
When a fluorine atom gains an electron, it forms a fluoride ion with a negative charge because it now has one more electron than protons. This gives it a full outer electron shell, making it more stable.
