The coordination number in hexagonal close-packed (hcp) structures is 12. This means that each atom in an hcp lattice is in contact with 12 surrounding atoms.
The volume of HCP is 8*pi*r^3 or 25.13*r^3

The packing fraction of the hexagonal close-packed (hcp) structure is calculated as (3 * sqrt(3) * (0.5)^2) / (2) which is approximately 0.74. Therefore, the packing fraction of the hcp form of titanium is around 74%.

HCP (hexagonal close-packed) and CCP (cubic close-packed) are both types of close-packed crystal structures. The main difference lies in the arrangement of atoms - HCP has two alternating layers of atoms, while CCP has three alternating layers. HCP has a hexagonal unit cell, while CCP has a cubic unit cell.
The atomic packing factor (APF) of a hexagonal close-packed (HCP) structure is calculated by taking the volume of atoms in a unit cell divided by the total volume of the unit cell. For HCP, the APF can be determined using the formula: APF = (3 * sqrt(3) * (0.25)) / (2 * sqrt(2)) This simplifies to APF = 0.74

Raising a notrump bid to 4NT is a natural invitation to slam, called Quantitative 4NT, or just "quant". Quant bids after a 1NT opening are more or less a math problem, keeping in mind that roughly 33 HCP are needed to be in small slam with two balanced hands.eg: Responding to 1NT (15-17 HCP)9-15 HCP--bid to game16-17 HCP--invite slam with a Quantitative 4NT response.Opener passes with a minimum.18-19--bid to slam
