III. Text Study Ex. 6. Read text 1 and find out: a) what matter is made up of; b) what the structure of an atom is. Text 1. ATOMIC STRUCTURE OF MATTER. ELECTRONS IN MOTION 1. The development of a scientific atomic theory started with Dalton in 1803. Since then through important discoveries scientists have been able to present a true picture of an atomic structure of matter. All matter is composed of atoms and molecules. Atoms are the smallest units of matter into which an element can be subdivided and still retain the properties of that element. A modern theory considers that at extremely high temperatures all molecules break up to form atoms or portions of molecules. The atoms or molecules making up a crystalline structure are arranged according to a definite geometrical pattern. This patterns is known to be a space lattice. 2. Atoms consist of a massive nuclei and small negatively charged particles called “electrons”. The mass of an electron was found to be about 2.000 times as small as the mass of the lightest atom, the hydrogen atom. The positive electricity is concentrated within the nucleus of dimensions very small compared with the total space occupied by an atom. This nucleus is responsible for practically the whole of the atomic mass. 3. An atom is a loose structure of electrons surrounding a heavy central core, the atomic nucleus, which is about one tenthousandth the size of the atom. It was later discovered that the nucleus consists of positively charged particles called “protons” and other particles of about the same weight without any charge, called “neutrons”. 4. The negative electron charge equals the positive nucleus charge: hence the atom has no charge. However, sometimes an atom may gain an electron, and then it has a negative charge. If an atom loses an electron, the nucleus protons are more numerous than the negative electrons, so the atom has a positive charge. 5. A body with a considerable excess of electrons has a strong negative charge; one with few electrons has a strong positive charge. Thus there is a difference of potential. If something allowing a free movement of electrons is placed between the negative and the positive charges, electrons move along this conduc
tive path to occupy the nuclei which lack electrons. This movement is an electric current and it can take place through any conductor. 6. A conductor readily allows the free exchange of orbital electrons, so electrons forming the electric current can move from atom to atom along the material. Silver and copper are good conductors. A perfect insulator would allow no exchange of electrons Hence there would be no movement from atom to atom, and no current would flow. Glass, mica and rubber are good insulators. Ex. 7. Find 2 words with: a) a close meaning weight – size – width – dimension – length unit – structure – matter – lattice – pattern loose – considerable – comparative – free – extreme consist – discover – arrange – be composed – retain conduct – increase – surround – flow – raise matter – structure – insulator – conductor – non-conductor charge – keep – occupy – move – retain b) an opposite meaning considerable – tight – strong – extreme – loose wide – weak – high - loose - strong compose – have – make up – charge – lack lose – occupy – move – gain – form wide – light – strong – heavy – deep small – scientific – dielectric – electric – conductive Ex. 8. Give the Russian equivalents to: To present a true picture of atoms and molecules, the smallest units of matter, the lightest atom, the nucleus is responsible for … , the development of a scientific theory, one tenthousandth the size of an atom, to move along the conductive path, no current flows, a strong negative charge, electrons forming the electric current, according to a definite pattern.

OUR ELECTRONIC WORLD Electronics is the tool of today. It has given us radar, automation, space vehicles*, radio telescopes, and a host of other inventions that have transformed our lives. Electronics means putting electrons to work. An electron is one of the particles in an atom, and travels at incredible speed round the nucleus. Also of the first importance are the facts that the electron has a negative charge, the nucleus a positive one. Many devices are used in our life. For example, transformers, transform or change one voltage to another, or perform other useful functions. A transistor is a device made from semiconductor material, e.g. a tiny* slice of germanium or silicon. It allows a small current (between base and emitter) to control a large current (between emitter and collector). It is used in TV, in computers, and in many other devices. In cathode ray tubes, an electron beam is deflected* by electric or magnetic field, and passes over the face of the tube. These tubes are employed in TV receivers, oscilloscopes and other equipment.
