The dot model for hexagonal close packing (HNC) represents the arrangement of atoms in a hexagonal lattice where each atom is depicted as a dot. In this model, atoms are positioned at the vertices and face centers of the hexagonal unit cell, illustrating the close-packed structure that maximizes density. This arrangement allows for efficient packing and is characteristic of materials like metals and certain crystalline solids. The dot model helps visualize atomic interactions and spatial arrangements in three dimensions.
HNC stand for "Higher National Certificate"
An HNC is equivalent to the first year of a uni course. An HND is equivalent to the second year of a uni course. As for a NVQ level 4 i don't think it is as good as a HNC.
There is no specific age requirement to pursue an HNC (Higher National Certificate) in the UK; however, most students are typically over 18 years old. Entry requirements may vary depending on the institution offering the course, but applicants are usually required to have a certain level of qualifications or work experience to enroll in an HNC program.

Yes, a Higher National Certificate (HNC) is considered a form of higher education qualification, typically awarded after completing a program of study at a college or university. In many contexts, obtaining an HNC signifies that you have graduated from that specific course of study. However, whether you are considered a "graduate" can depend on the specific definitions used by educational institutions and employers.
Guanidine is a base. The chemical formula is HNC(NH2)2.
no it is the same level just a different name
In England, Wales and Northern Ireland, a HNC (previously a level 4 qualification) is now Level 5 on the National Qualifications Framework.In Scotland, an HNC is Level 7 on the Scottish Credit and Qualifications Framework.

Yes, you can often receive credits towards a Higher National Certificate (HNC) with an NVQ Level 3, as both qualifications may cover similar skills and knowledge relevant to certain fields. However, the specific transfer of credits depends on the institution and the program requirements. It's best to consult with the educational provider offering the HNC to understand their policies on credit transfer.
HND is higher than a HNCHNC stands for Higher National Certificate whereas HND stands for Higher Nationla Diploma.HNC requires ten units and a HND requires 16 units.A HNC can be topped up to a HND with the additonal 6 units.A HND is therefore higher than a HNC.A HNC starting from scratch will take 4-5 years (No prior qaulifications in the given field.)HND Courses are normally only 1 year. But for some strange reason, Colleges will class them as 2-year courses because you MUST do HNC qaulification with them first.
For models there are sites such as Models (dot) com, Model Mayhem and One Model Place.
A Lewis dot model is a simple diagram that represents the outermost valence electrons of an atom, typically using dots to represent electrons. It is used to illustrate the bonding between atoms in a molecule or compound. Lewis dot models help to predict the reactivity and chemical behavior of elements.
