Answer:
The metal cube lattice is made of only one kind of atom.
Explanation:
As we know that metallic crystals are made up of only one kind of element. A metal crystal is actually a huge sea of positive charges embedded in the layers of negative charges (electrons). The whole crystal is made up of same kind of atoms, e.g crystals of gold, crystals of iron.
If we talk about structure of metallic crystal, it can be body centered cubic, simple cubic, hexagonal or close cubic packing.
Now, coming towards the ionic crystals, we know that they are basically the crystals of ionic compounds like sodium chloride or cesium chloride. These crystals are formed due to ionic bonding between two or more than two kinds of elements/atoms. It is not possible for an ionic crystal to be composed of only one kind of atom. As far as structure is concerned, they can have different structure based on bonding between atoms in an ionic compound, e.g NaCl has octahedral geometry.
Therefore, it is very evident that best option is A.
Answer:
The general form of a partition function is a sum over the states of the system,
Explanation:
qTr + qRo+ qVi +qEl= Qt
Qt= total energy
Answer:
its a chemical compound made from carbamic acid that replaces one or more hydrogen atoms by other functional groups
Answer:
Atomic mass of Gallium is 69.7230 amu
Explanation:
100 atoms of gallium contains 60.11 number of 
atoms and 39.89 number of 
atoms.
Therefore atomic mass of gallium is given by-
= 
= 69.7230 amu
