The reader is taken through a wide range of topics by a combination of clearly written text, beautiful illustrations and more interactive learning, including problems and screencasts. Two examples where the book gives excellent coverage of areas that students often find difficult are NMR splitting (covered by a very clear diagram showing how splitting relates to the energy levels within the nucleus) and chemical kinetics (the section includes screencasts to explain steady-state and transition state theory).
I like the way that atomic structure is approached in this book, starting with material that all students will understand from A-level chemistry (eg flame tests), but leading through in a logical manner to the Schrdinger equation. It also offers extra material for those who want it, for example on angular wavefunctions (there is a very useful Maths Toolkit at the end of the book for those who lack confidence or understanding in mathematics).
The section on molecular orbitals is very clear, leading to more difficult topics such as s-p mixing and relating back to experiments, showing how photoelectron spectroscopy allows us to determine orbital energies.
I find the descriptive inorganic chemistry sections slightly more disappointing. The chapters on p- and d-block chemistry seem a little superficial and some topics are almost completely ignored. For example, p-block organometallics are only allocated one page. Crystal field theory is covered in the d-block chapter but there is no mention of molecular orbital theory, which some advanced students may want to consider having studied such theory in p-block chemistry. These are not serious criticisms, just a comment on the balance of the book, which I feel is excellent on theory but a little weaker on description.
Chemistry3 establishes the fundamental principles of all three strands of chemistry; organic, inorganic, and physical. By building on what students have learned at school, using carefully worded explanations, annotated diagrams and worked examples, it presents an approachable introduction to chemistry and its relevance to everyday life. This 4th edition includes new and updated online resources, including videos and screencasts, as well as new ChemTube3D interactive molecular structures.
There is a lot of interesting science to investigate in this world. Not all of the science is done by men wearing white coats and working in laboratories. All of the world around us involves science. Students and teachers can investigate some pretty interesting stuff without requiring a laboratory or expensive equipment.
The Countertop Chemistry resources linked below include activities on the properties of matter, the properties of gases, micro-chemistry reactions, properties of solutions, suspensions, and colloids, and many other fun chemistry investigations.
Many of these activities can serve as teacher demonstrations or hands-on student activities. As much as possible we try to use simple and cheap materials that you might have at home. The activities can be used at a variety of grade levels from K-12. Each activity includes directions, questions, material lists, and tips for carrying out the activity. Have fun with Chemistry!
Some units are squared, such as an area of 150 m2, or cubed, such as a volume of 25 cm3. Remember that m2 means m*m, and cm3 means cm*cm*cm. When performing unit conversions on a unit raised to a power, you need to remember to raise the conversion factor to the power as well. That is, you need to convert both meters in m2, or all three centimeters in cm3. This is illustrated in the following examples.
You can work with the units independently, so you will leave m alone. The conversion needed is 60 s = 1 min. The conversion can be squared (remembering to square the 60 when entering into the calculator)
In chemistry we will use cm3 for volume or the volume unit L (with or without metric prefixes). When converting between these units, you should know that 1 cm3 = 1 mL. Note that the centimeter is cubed but the milliliter is not. Therefore, in the following example going from m3 to cm3 requires a cubed conversion factor but going from mL to L does not.
Chemistry is widely considered to be the central science: it encompasses concepts from which other branches of science are developed. Yet, for many students entering university, gaining a firm grounding in chemistry is a real challenge. Chemistry3 responds to this challenge, providing students with a full understanding of the fundamental principles of chemistry on which to build later studies.

The annual Nobel prizes celebrate, in part, the very best of the latest research and discoveries in physics and chemistry. With previous winners, including household names Albert Einstein and Marie Curie, there is no doubt about the prestige which comes with winning such an award. This year saw 5 laureates across the two fields, with three winning the physics prize and two claiming the chemistry one.
What does this new method mean for science? Gene functions can now be studied more easily. Plants can now be given specific qualities that will help them survive better in their changing climates. Its medicinal value is very high , with contributions to not only immunotherapies for cancer but even the potential to cure inherited diseases. Trials are in fact taking place. New techniques for fixing genes in organs such as the brain are also in development.
However, as with all technology, there is the opportunity for abuse. Ethical issues come hand in hand with many advances in science, and anything involving genes is no exception. The genetic scissors could be used to genetically modify embryos.
Although there are laws and rules which are in place to control the use of genetic engineering, any experiment that will involve humans or animals has to be allowed by ethical committees first. Nonetheless, this is still certainly a tool which could help in solving several problems that humanity faces.
The goal of the Chemistry Climate Working Group (CCWG) is to continue to develop the representation of chemical gas and aerosol species in the CESM with the aim to improve our knowledge of the interactions between chemistry, aerosols and climate. CCWG science topics include past, present and future atmospheric composition in the troposphere and lower- to mid- stratosphere; interactions between atmospheric composition and other components of the Earth System (including land, ocean and ice); stratosphere-troposphere coupling; aerosol direct and indirect effects on the Earth's energy balance; aerosol effects on precipitation; and the impacts of chemistry and aerosol on both climate and air quality across multiple spatiotemporal scales.
CESM2 CAM-chem will serve as the new workhorse model to perform fully-coupled experiments for CMIP7, including comprehensive tropospheric and stratospheric chemistry (MOZART TS1). CAM-chem will provide the aerosol and chemistry fields to be prescribed in CAM7 with simple chemistry for longer climate-scale simulations. The new model lid is at 80 km, and comprises 93 vertical layers with a default horizontal resolution of about 1 degree on a cubed sphere, run on a spectral element dynamical core.
CAM-chem can be run as a free-running climate model, coupled to the land model (CLM), and optionally to the ocean and ice models. It can also be nudged to winds and temperatures of meteorological reanalyses, with a default of using MERRA2 and GEOS5 fields, for detailed comparisons to field experiments and specific observations.
