The Be2+ cation is smaller in size (being above the rest of the group 2 elements) and hence has high charge density. This enables it to easily polarise the comparatively larger Cl- anion, which results in a covalent characteristic of the compound. Dative bonding (a special type of covalent bond in which the shared electrons come from one of the atoms only) occurs in the compound and BeCl2 usually occurs as a dimer i.e Be2Cl4 (polymeric type) based on the linear molecular structure of BeCl2.
Polarisation occurs between a small cation with high charge density and a larger anion. Since the size of the cations of the group 2 elements increases down the group (more atomic radius), charge density around the cation decreases and hence their ability to polarise the Cl- also decreases, resulting in an ionic compound.

When beryllium loses electrons to fluorine what is the process called?
Wouldn't it be the formation of an ionic compound, BeF2. Because fluorine needs to gain one electron to become stable like the noble gases. In turn, beryllium needs to lose two electrons to become stable. So, two fluorine atoms react with one beryllium atom. The two fluorines are called anions (ions with (-) charge) and the beryllium is a 2+ cation (or ion with (+) charge). Then, to cancel out the charges, they bond together to form what is known as an ionic compound.

When two element form a covalent bond what do the electrons do?
A covalent bond is a form of chemical bonding that is characterized by the sharing of pairs ofelectrons between atoms, and other covalent bonds. In short, the stable balance of attractive and repulsive forces between atoms when they share electrons is known as covalent bonding.[1]Covalent bonding includes many kinds of interaction, including σ-bonding, π-bonding, metal to metal bonding, agostic interactions, and three-center two-electron bonds.[2][3] The term covalent bond dates from 1939.[4] The prefix co- means jointly, associated in action, partnered to a lesser degree,etc.; thus a "co-valent bond", essentially, means that the atoms share "valence", such as is discussed in valence bond theory. In the molecule H2, the hydrogen atoms share the two electrons via covalent bonding. Covalency is greatest between atoms of similar electronegativities. Thus, covalent bonding does not necessarily require the two atoms be of the same elements, only that they be of comparable electronegativity. Although covalent bonding entails sharing of electrons, it is not necessarily delocalized. Furthermore, in contrast to electrostatic interactions ("ionic bonds") the strength of covalent bond depends on the angular relation between atoms in polyatomic molecules.
Why does beryllium chloride has more covalent character than barium chloride?
Beryllium chloride has more covalent character than barium chloride because beryllium is a smaller cation with a higher charge density, leading to stronger interactions with the chloride anions. This results in a more polar covalent bond in beryllium chloride compared to the more ionic bond in barium chloride due to the larger size and lower charge density of barium.
Is beryllium perchlorate ionic or covalent?

What is the ionic compound of BeCl2?
The ionic compound of BeCl2 is beryllium chloride. It is formed by the combination of beryllium (Be) and chloride (Cl) ions in a 1:2 ratio.
Is BeH2 and HCl ionic or covalent?
BeH2 is a covalent compound because beryllium typically forms covalent bonds with hydrogen. HCl is considered an ionic compound because hydrogen chloride typically forms an ionic bond between the hydrogen and chlorine ions.
