## What is the coordination number for NaCl?

6
The NaCl structure shows each Na+ ion having a Cl− neighbour above and below, to the left and to the right and to the front and to the rear. The concept is true for cl– ion also. For both ions, the coordinating number is 6.

What are the coordination numbers of the Na+ and Cl ions?

What is coordination number of Na^(+) and Cl^(-) ion in Nacl? Each has a coordination number of 6, i.e. each ion is surrounded by six oppositely charged ions.

Why is the coordination number of sodium 6?

NaCl has a fcc lattice in which sodium is at all corners and chloride ions are on the face centre. Here, each ion is attached with 6 other ions. So, the coordination number of each ion is 6.

### How do you find the coordination number of sodium?

The coordination number of Na in Na2O is 4. Na+ ion is surrounded by four oxide ions and O2- ion is surrounded by eight Na+ ions hence the coordination number of Na in Na2O is 4.

How many chloride ions are surrounding sodium ion in sodium chloride?

six ions
Each ion of chloride is surrounded by six ions of sodium and each ion of sodium is surrounded to six ions of chloride.

What are the coordination numbers of the Na+ and Cl ions ie how many Cl ions surround each Na+ ion and vice versa?

Each Na+ ion is surrounded by six Cl– ions and each Cl– ion is surrounded by six Na+ ions. Thus, both Na+ ions and Cl– ions have a coordination number of six. Hence, the structure has 6 : 6 coordination.

#### What is the coordination number of CaF2?

8
Specify the co-ordination number of Calcium and Fluoride ion in the compound Calcium fluoride (CaF2) In CaF2 the coordination number of Ca2+ is 8. As it is surrounded by 8 F ions.

What is the coordination number of sodium in sodium oxide?

four
Hence the coordination number of sodium ions is four in sodium oxide.

How many chloride ions are surrounding sodium ion in NaCl A 4 B 8 C 6 D 12?

Now, since sodium ions are present in the octahedral voids, therefore they will be surrounded by six chloride ions.

## Which is the example of 8 8 coordination in following?

Solution: Each Cs+ is surrounded by eight Cl−ions in CsCl crystal lattice because its co-ordination number is 8 : 8.

In which compound is 4/4 coordination found?

Zinc blende (ZnS) has fee structure. It is an ionic crystal having 4:4 coordination number.

What is the coordination number of chloride in sodium chloride?

Likewise, six sodium ions immediately surround each chloride ions, making the coordination number of chloride also equal to 6. Because the formula unit of sodium chloride displays a 1:1 ratio between the ions, the coordination numbers must be the same. Figure 8.8

### How can we say that NaCl structure has 6-6 coordination?

So, we can say NaCl structure has 6:6 coordination because coordination number defines the number of atoms or ions immediately around a particular atom or ion. The corner site of the NaCl crystal structure is shared by the 8 unit cells (1 corner equal to 1/8 of ion or atom) and the 6 face site is shared by 1/2 atoms or ions.

What are the 5 properties of NaCl?

Properties of Sodium Chloride – NaCl. NaCl. Sodium Chloride. Molecular Weight / Molar Mass of sodium chloride. 58.44 g/mol. Density of sodium chloride. 2.165 g/cm 3. Boiling Point of sodium chloride. 1,413 °C.

What is the name of the compound NaCl?

Sodium Chloride is an ionic compound with the chemical formula NaCl. Sodium Chloride is also known as salt. It occurs in oceans and sea waters.
