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.
What else can I help you with?
Beryllium Be and chlorine Cl form a binary ionic compound with a one-to-two ratio of beryllium ions to chloride ions The formula for the compound is?
Beryllium chloride, BeCl2
What type of bond is between oxygen and beryllium?
2 Be + O2 = 2 BeO
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.
Can carbon only form ionic compounds.?
No, carbon cannot only form ionic compounds; it primarily forms covalent compounds. This is due to its ability to share electrons with other elements, particularly nonmetals, to achieve stability. Carbon's tetravalent nature allows it to form a wide variety of organic molecules, including hydrocarbons and complex biomolecules, through covalent bonding. Ionic compounds are more commonly formed by metals with significantly different electronegativities.
NaCI and Fe2O3 are scientfic what?
First, the correct formula is NaCl (with a lowercase L, not an uppercase I). NaCl (sodium chloride) and Fe2O3 (Iron III oxide) are chmical compounds. Ionic compounds to be specific.
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?
Covalent
Is sodium chloride ionic or covalent?
No, but the bond in sodium chloride is 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.
Which atoms will pair up with beryllium?
Beryllium typically forms covalent bonds with atoms like oxygen, which can form a beryllium oxide compound. Beryllium can also form ionic bonds with atoms like chlorine, which can form beryllium chloride.
Is beryllium fluoride ionic or covalent?
Beryllium fluoride is an ionic compound. Beryllium, a metal, forms cations while fluoride, a nonmetal, forms anions, resulting in a transfer of electrons and the formation of ionic bonds.
