He explained that a fixed amount of energy a quantum of energy is needed for an electron to move from one orbit to the next. Serious students may want to supplement the materials with more level-specific guides, but generally speaking this is an excellent and comprehensive revision tool. The real strength of this book lies in the story behind it, the credentials of the author, and his friendly, understandable tone. The relative masses and charges of electrons, protons and neutrons are shown in the table.
However, he had no evidence. Highly critically acclaimed, the guide covers the techniques required to do well. Fractional distillation works by using a tall tower of gaps and surfaces, which are gradually colder towards the top. The guides are even available on Amazon Kindle, so they can be accessed from anywhere. This guide uses colourful diagrams, an attractive format, and clear language to present the subject matter in a way that is accessible to all.
The real strength of this book lies in the story behind it, the credentials of the author, and his friendly, understandable tone. Currently, scientists believe atoms are made of three important particles — protons, electrons and neutrons. In addition to this, the guides encourage students to adopt their own view on topics, to fulfil the all-important critical analysis criteria necessary to hit the highest GCSE grades. A typical atomic radius is about 0. Key words atomic number electron neutral neutron proton Did you know? The activities for studying, along with descriptions of what needs to be done to attain a particular grade, provide yet more valuable assistance for students and give honest and direct advice.

Negative electrons were thought to be embedded in a ball of positive charge, rather like the fruit the electrons are part of a pudding the ball of positive charge. Otherwise dense and tricky material is broken down into digestible chunks, without omitting the important parts.
A particularly interesting feature is the use of topics to think and write about, in place of conventional practice questions, which encourage students to think more critically and addresses more general skills.
Section F: Sums This section deals with all the calculations involving relative atomic masses and moles up to and including simple titration and electrolysis calculations.
Key information At each stage, the explanations of atomic theory were provisional until more convincing evidence was found to make the model better. Key information It is because a helium atom has two protons that it has an atomic number of 2. Section B: Some essential background chemistry This is a lengthy section which covers the important lab-based chemistry: Reactivity series Salts Simple analysis Periodic Table: including some history, the structure of the table, the noble gases, Groups 1 and 7, and an introduction to transition metals Electrolysis and electrochemical cells Energy changes in reactions Section C: Large scale chemistry This covers the extraction of several metals, and the chemistry of salt and limestone.
All the relevant topics are covered in sufficient detail, interspersed with practice exam questions to allow students to test themselves as they go through. However, since then, GCSE syllabuses have changed, particularly in the order in which they do things, and with more stress on making chemistry "relevant" - some would argue, more dumbed down!
These titles are comprehensive and friendly guides that have a great deal to offer any student — they take much of the pain out of the revision process. In94 years later, J. The space between the nucleus and the electron shells is empty space. Figure 1.
Fractional distillation works by using a tall tower of gaps and surfaces, which are gradually colder towards the top. Masses and charges The nucleus of an atom is made up of particles protons and neutrons that are much heavier than electrons. Atoms are very small. The book is simple, enjoyable, and helps students feel confident and sure in their ability to do well by walking them through the process in a pleasant and supportive way.
Admittedly, much of the information in the book is not new, and can be found online or with the help of a teacher. Eventually nearly all the gases in the mixture will condense and be collected as separated liquids. Nevertheless, the guide is full of useful advice, confidently backed with solid empirical evidence, giving students a reliable and useful weapon in their fight against GCSE exams.
From examination this syllabus will no longer be regulated by the qualifications and examinations regulators in England, Wales and Northern Ireland.
We have seen how ideas about atoms have changed over the years. We can explain how everything, including ourselves, is made by using ideas and models of atoms. The material stays highly on-topic throughout, teaching only information that will be useful in the exam instead of filling out the pages with irrelevant facts and details.
The atomic number for helium is 2 because it has two protons. Use ideas about opposite charges. The relative masses and charges of electrons, protons and neutrons are shown in the table.
Magnification x 16 There are the same number of protons and electrons. Different editions of the book exist, focusing on different exam boards, which is important when the subject matter and exam structure varies depending on who produced the test.
There are questions at the end of each chapter to test understanding, and a set of GCSE-style exam questions at the end of each section.
