All crystal lattices are built of repeating unit cells. In a unit cell, an atom's coordination number is the number of atoms it is touching. ... The body-centered cubic (bcc) has a coordination number of 8 and contains 2 atoms per unit cell. The simple cubic has a coordination number of 6 and contains 1 atom per unit cell.

Both group form ionic compound but only Halogens for covalent bonds. THe Alkali metals have low densities while the Halogens have high densities and the melting point and boiling point patterns are opposite for the Halogens it increases whereas for the Alkali metals it decreases.

❄️❄️Isomerism means same crystal structure at given temperature and pressure. ⚡have different crystal structures. ❄️⚡Because there atomic redius is different. ❄️Thus, NaCl and KCl are not isomorphous !

Yes! Lattice energy is usually the largest factor in determining the stability of an ionic solid. The extra energy gained by the lattice energy more than compensates for the energy needed to transfer a chloride ion from one PCl5 molecule to another. Thus, PCl5 exists as an ionic solid.

Sodium chloride, regular table salt, is also known as the mineral halite. The diagram to the right shows how sodium and chlorine atoms pack tightly together to form cube-like units of the compound NaCl. Crystals of table salt imitate this structure-they're shaped like little cubes.

It follows that there are 2 tetrahedral and 1 octahedral holes per anion in a fcc structure where the anions make the close-pack framework. Thus the coordination number for Na+ is 4 and for O2- is 8. Consequently the stoichiometry for sodium oxide is Na2O. e tetrahedral holes are filled by the small zinc ions.

It is made of two atoms and is called a diatomic molecule. A crystal of NaCl(s) is not a molecule: it is an ionic lattice made up of an indeterminate number of atoms. Carbon dioxide is a molecule made of two oxygen atoms bonded to a carbon atom. It contains three atoms and is called a triatomic molecule.

In CO32- all the elements have a full octet, all have 8 electrons around each other. In CS2, C has 2 double bonds which gives it a full octet, S also has 8 electrons around it. ... BBr3 also does not obey the octet rule as B only has 6 electrons around it.

-AgBr ( Silver Bromide ) is used for photography.It is because it is sensible to light. ... -When the film is exposed to light, the silver halide crystals change to record a latent image that can be developed into a photograph.

Group 2 elements are held together by metallic bonds. ... Moving down the group, the atoms form different crystal structures in the solid phase. Beryllium and magnesium each have a hexagonal close-packed structure; calcium and strontium form face-centered cubic structures; the structure of barium is body-centered cubic.

In CSI, the constituent ions are Cs+ and I-. Both these ions are large in size, as a result of which their hydration enthalpy is small. Lower is the hydration enthalpy, lower is the solubility of salt. Hence CSI have lower solubility in water.

Carbon tet is nonpolar. A good solvent for NaCl would be polar and the negative end of the solvent would surround sodium ions and the positive end would surround chloride ions.

An example of an ionic solid is table salt, NaCl. ... Covalent-network (also called atomic) solids—Made up of atoms connected by covalent bonds; the intermolecular forces are covalent bonds as well. Characterized as being very hard with very high melting points and being poor conductors.

The BCC unit cell consists of a net total of two atoms, the one in the center and eight eighths from the corners. In the FCC arrangement, again there are eight atoms at corners of the unit cell and one atom centered in each of the faces.

Silver chloride, silver bromide (AgBr) and silver iodide (AgI) are the three silver "halide" compounds used in photography. The halide elements include fluorine (F), chlorine (Cl), bromine (Br) and iodine (I).
