Closed packed derections.. are derections of the lines drawn through atoms such that no void space is in bitween..
Refer this, i also got the idea from here

What else can I help you with?
Is zinc an example of pure metal with a hexagonal close-packed arragements?
Yes, zinc is a pure metal that adopts a hexagonal close-packed (HCP) crystal structure at room temperature. In its solid form, zinc atoms are arranged in a close-packed hexagonal lattice structure, making it an example of a pure metal with HCP arrangements.
Particles in a solid are packed so close together they can only what?
Particles in a solid are packed so close together that they can only vibrate in place. This is why solids have a fixed shape and volume. The strong forces of attraction between particles hold them in a fixed position.
How would you characterize the diffusion of solid liquid and gas?
In a solid, particles are closely packed and vibrate in fixed positions. In a liquid, particles are close but can move past each other. In a gas, particles are far apart and move freely in all directions.
What is the lattice parameter of a hexagonal close-packed (hcp) crystal structure?
The lattice parameter of a hexagonal close-packed (hcp) crystal structure is the distance between the centers of two adjacent atoms in the crystal lattice. It is typically denoted as "a" and is equal to 2 times the radius of the atoms in the structure.
Where are molecules close together?
Molecules are close together in solids because the particles are tightly packed and have little room to move around. This results in a fixed shape and volume for solids.
How many slip system are there in hcp crystal?
In a hexagonal close-packed (hcp) crystal structure, there are typically 12 slip systems. These consist of three primary slip directions (the close-packed directions) and four distinct slip planes. The primary slip directions are along the close-packed directions of the hexagonal lattice, specifically along the directions, while the slip planes are the (0001) basal plane and the three prismatic planes. This combination allows for significant plastic deformation under applied stress.
What is a Hexagonal close packed lattice and what is sign it?
What is a Hexagonal close packed lattice and what is sign it?"
What happens when particles in a solid are packed so close together?
particles in a solid are packed so close together they can only
What is the two dimensional coordination number of a molecule in square close packed layer?
In square close-packed layer, a molecule is in contact with four of its neighbours. Therefore, the two-dimensional coordination number of a molecule in square close-packed layer is 4.
Are gas particles packed close together?
No, they are spread out. Gases are less dense than solids and liquids, which is caused by the particles being spread out.
What is a synonym for dense?
compact, packed, close, compressed
What is CPH?
CPH also frequently called HCP - is Close Packed Hexagonal (or hexagonal close packed). It is an arrangement of atoms in a crystal structure. It can mean quite a few other things, one of which is the IATA code for Copenhagen airport. See the related link for more information.
How many neighbors does a hexagonal close packed crystal have?
it has 12 neighbors
Why FCC crystal structure has more slip plans thenHCP?
FCC crystal structure has 12 slip planes because of its cubic symmetry, which allows slip to occur in many directions. HCP crystal structure, on the other hand, has 3 slip planes due to its hexagonal close-packed arrangement, which restricts the slip to fewer directions.
What type of crystalline structure does cobalt possess?
According to wikipedia, metallic cobalt occurs as hexagon close-packed and face-centred cubic.
Why does slip occur on close-packed planes?
Slip occurs on close-packed planes because the atoms in these planes are closely packed together, making it easier for them to slide past each other when a force is applied. This slipping motion is a result of the arrangement of atoms in the crystal lattice structure of the material.
Are solid particles packed close together?
As compared to liquids or gasses, yes they are.
