WHAT IS A MOLECULE. A molecule is defined as two or more atoms of the same element different element that are bound together. A molecule may be homonuclear, which means, it consists of atoms of one chemical element, as with oxygen (O 2); or it may be heteronuclear, a chemical compound composed of more than one element, as with water (H 2 O). GCSE CHEMISTRY Higher Tier Paper 1 8462/1H H . 2 ... 0 6 . 2 Explain why graphite conducts electricity. Answer in terms of the structure and bonding 4. Why can we see through diamond but not aluminum? How about graphite? 5. Why does aluminum (and for that matter all metals) conduct electricity? What must be happening at the atomic-molecular scale for this to occur? 6. What does the fact that diamond doesn’t conduct electricity tell you about the bonding in diamond? 7. Why do you assume that the healthcare system won't use such technologies? History suggests that every medical technology that works eventually is used. Very expensive treatments are sometimes justified on political grounds, but more often they are justified on the grounds that they will decrease overall expenditure by, for example, reducing ... Oct 01, 2019 · 39. A non-metal X exists in two different forms Y and Z. Y is the hardest natural substance, whereas Z is a good conductor of electricity. Identify X, Y and Z. Answer. ‘X’ is carbon, ‘Y’ is diamond as it is the hardest natural substance and ‘Z’ is graphite as it is good conductor of electricity. 40. Why does calcium float in water ... Graphite conducts electricity due to the ‘spare’ electrons being delocalised between the layers. Why is graphite used in pencils? Properties and uses. The layers in graphite can slide over each other because the forces between them are weak. This makes graphite slippery, so it is useful as a lubricant .

Sep 05, 2008 · The carbons form only three bonds because they are sp 2 hybridized (hence the -ene suffix). This means that there are only 3 hybrid orbitals that can form bonds, similar to the carbon in something like ethylene, H2C=CH2 (however, graphene doesn't have a double bond).
Graphite consists of several 2D layers of covalently bonded atoms stacked together. Their configuration in this substance allows Their configuration in this substance allows electrons to flow freely and thus conduct electricity, which is merely the flow of electrons from one place to another.
▸ Introduction to deep learning : What does the analogy "AI is the new electricity" refer to? AI runs on computers and is thus powered by electricity, but it is letting computers do things not possible before. Similar to electricity starting about 100 years ago, AI is transforming multiple industries. Correct. Yes.
Electricity and all its observable effects result from properties of stationary or moving electric charges. But if extra charges of one type are added, the material is left with a net charge and electrical effects result. Charges can be transferred from one material to another by rubbing them...

Oct 16, 2015 · The report does admit that a TfL takeover in South London wouldn’t lead to an automatic cut in all fares. As it points out, however, what TfL do bring to the table is a much simpler fares system, as well as a variety of free travel concessions. These aren’t the only potential savings that the report argues devolution could bring.
Metals conduct heat and electricity. It is by virtue of this property of metals that heat, and electricity can pass through them. Every metal is a good conductor of heat and electricity. Note: Silver is the best conductor of heat and electricity, copper is also a good conductor. The worst conductor of heat is lead whereas Iron and mercury are ...
Hey guys just a question from an electrical engineer, does the metal conduct electricity? The tip itself is non-conductive, and the shaft of the Inkless Metal Pen is made from anodized aluminum which is also non-conductive.
