  2. Metallic bonding - Wikipedia

    en.wikipedia.org/wiki/Metallic_bonding

    Metallic bonding is mostly non-polar, because even in alloys there is little difference among the electronegativities of the atoms participating in the bonding interaction (and, in pure elemental metals, none at all). Thus, metallic bonding is an extremely delocalized communal form of covalent bonding.

    The highest grade achievable is an A. An FSMQ Unit at Advanced level is roughly equivalent to a single AS module with candidates receiving 10 UCAS points for an A grade. Intermediate level is equivalent to a GCSE in Mathematics. Coursework is often a key part of the FSMQ, but is sometimes omitted depending on the examining board.

  5. Uniform Mark Scheme - Wikipedia

    en.wikipedia.org/wiki/Uniform_Mark_Scheme

    The A* grade is only obtainable in the A2 level. For all subjects this requires a student to obtain 80% of all the UMS available in addition to 90% of the UMS available in the A2 modules. However, this is different in A level maths: to obtain an A* in A level maths one must obtain 80% of the available UMS in the whole A level and at least 90% ...

    Edexcel, another British exam board, also had similarly low grade boundaries. Subsequently, Ofqual said that they were confident the grade boundaries this year were "sound", so shifted their focus onto the previous year's grade boundaries for the new Mathematics A-Level for the 2,000 students who sat it after studying it for one year.

    In June, Paper 3 of the Mathematics GCSE (Higher Tier, 1MA1/03) appeared to contain an exam question which was published in an AQA (another British exam board) Further Mathematics textbook. The exam question had the same diagram, values and answer as the question in the textbook. Pearson Edexcel said that they were investigating how this might ...

  8. Bonding in solids - Wikipedia

    en.wikipedia.org/wiki/Bonding_in_solids

    Metallic bonding, which forms metallic solids; Weak inter molecular bonding, which forms molecular solids (sometimes anomalously called "covalent solids") Typical members of these classes have distinctive electron distributions, [2] thermodynamic, electronic, and mechanical properties. In particular, the binding energies of these interactions ...

  9. GCE Ordinary Level - Wikipedia

    en.wikipedia.org/wiki/GCE_Ordinary_Level

    The Scottish equivalent was the O-grade (replaced by the Standard Grade). The AO-Level ( Alternative Ordinary Level ) was formerly available in most subject areas. Sometimes incorrectly known as the Advanced Ordinary Level, the AO-Level syllabus and examination both assumed a higher degree of maturity on the part of candidates, and employed ...
