Answer:
The two-dimensional crystal is shown in the attached file.
Explanation:
The two-dimensional crystal that contains six formula units of sodium chloride in the solid state is shown in the attached file. In the two-dimensional crystal, there are ion pointing outward and there are others pointing inward. Each sodium ion in the crystal is surrounded by 6 chloride ions. Similarly, each chloride ion in the crystal is also surrounded by 6 sodium ions. Due to this arrangement, the number six (6) is commonly known as the the coordination number of sodium and chloride ions.
Answer:That all noble gases will have 8 valence electrons which makes a atom stable
Explanation:
Answer: Fe2O3
Explanation: By applying crisscross method, the formula will be Fe2O3.
Explanation :
According to the molecular orbital theory, the general molecular orbital configuration will be,
As there are 7 electrons present in nitrogen and 9 electrons in fluorine.
(a) The number of electrons present in molecule = 7 + 9 = 16
The molecular orbital configuration of molecule will be,
The formula of bonding order =
The bonding order of =
(b) The number of electrons present in molecule = 7 + 9 - 1 = 15
The molecular orbital configuration of molecule will be,
The bonding order of =
(c) The number of electrons present in molecule = 7 + 9 + 1 = 17
The molecular orbital configuration of molecule will be,
The bonding order of =
