Why is the bond in beryllium chloride covalent rather than ionic?
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 is beryllium and why is it so important?
Beryllium is a chemical element. It's used as a hardening agent in alloys. It's widely used in the aerospace industry. To find out all the details about beryllium, type in "beryllium" in your web browser and you'll get several websites describing it.
What has 4 neutrons is metallic and has 4 electrons?
BerylliumThe fourth element in the Periodic Table, Beryllium has four neutrons and electrons, but it doesn't necessarily have four protons. Beryllium is also a type of metal.
What type of activity is the ability of your lungs and heart to supply the muscles with oxygen?
Aerobic
What type of blood does the coronary artery deliver to the heart?
The coronary artery delivers oxygenated blood to the heart. The coronary arteries supply the heart muscle with oxygen and nutrients.
What type of bond will form between oxygen and oxygen?
covalent bond
What type of bond is BeO?
BeO forms an ionic bond, where beryllium donates electrons to oxygen, resulting in the formation of Be^2+ and O^2- ions that are held together by electrostatic attraction.
What type of bond is between oxygen atoms of gaseous oxygen?
The bond between oxygen atoms in gaseous oxygen is a covalent bond. In this type of bond, the atoms share electrons to form a stable molecule.
What type of bond will form between sulfur and oxygen?
A covalent bond will form between sulfur and oxygen. This type of bond involves the sharing of electrons between the two atoms.
What type of bond forms between barium and oxygen?
An ionic bond forms between barium and oxygen.
What type of bond exist between carbon and oxygen?
A covalent bond typically exists between carbon and oxygen. This bond involves the sharing of electrons between the two atoms.
What type of bond does carbon and oxygen form?
Carbon and oxygen typically form a covalent bond when they bond together. This type of bond involves the sharing of electrons between the two atoms, resulting in a strong bond.
What type of bond is present between oxygen and hemoglobin?
The bond between oxygen and hemoglobin is a reversible coordination bond formed between the iron atom in the heme group of hemoglobin and the oxygen molecule. This bond allows hemoglobin to transport oxygen from the lungs to tissues throughout the body.
What is bond type of ocl2?
OCl2 has a covalent bond type. It is formed by sharing electrons between the oxygen and chlorine atoms.
What type of bond forms between Cardon and oxygen?
A covalent bond forms between carbon and oxygen when carbon dioxide (CO2) is formed. In this bond, carbon shares electrons with oxygen to achieve a stable electron configuration.
What type of bond is formed between carbon and oxygen?
polar covalent
