- Ex.7 Read and translate the text. Blocks of the Periodic Table
| Ex. 6 Translate the following sentences into Russian or Kazakh.
1.One of the cornerstones of modern chemical theory is the Periodic Law. 2. Zwitterions contain an anionic centre and a cationic centre in the same molecule, but are not salts. 3. Aqueous solutions of salts can be also electrolyzed because they are also electrically conductive. 4. A molten salt is an example of something that may be electrolyzed because salts are composed of ions. 5. All elements from atomic number 1 (hydrogen) to 118 (ununoctium) have been synthesized. 6. Hexane (C6H14) is also a widely used non-polar, non-aromatic solvent. 7. Salts are composed of cations (positively charged ions) and anions (negative ions) so that the product is electrically neutral (without a net charge). 8. Neutral salts are those that are neither acid nor basic salts. Ex.7 Read and translate the text. Blocks of the Periodic Table The Periodic Table does more than just list the elements. The word periodic means that in each row, or period, there is a pattern of characteristics in the elements. This is because the elements are listed in part by their electron configuration. The Alkali metals and Alkaline earth metals have one and two valence electrons (electrons in the outer shell) respectively. These elements lose electrons to form bonds easily, and are thus very reactive. These elements are the s-block of the periodic table. The p-block, on the right, contains common non-metals such as chlorine and helium. The noble gases, in the column on the right, almost never react, since they have eight valence electrons, which makes it very stable. The halogens, directly to the left of the noble gases, readily gain electrons and react with metals. The s and p blocks make up the main-group elements, also known as representative elements. The d-block, which is the largest, consists of transition metals such as copper, iron, and gold. The f-block, on the bottom, contains rarer metals including uranium. Elements in the same Group or Family have the same configuration of valence electrons, making them behave in chemically similar ways. Vocabulary blocks of the Periodic Table – блоки периодической системы just – просто to list – называть to mean – значить each row – каждый ряд pattern – образец in part – частично configuration – конфигурация, строение alkali metal – щелочной металл alkaline earth metal – щелочноземельный металл outer shell – внешняя оболочка respectively – соответственно to lose – терять to form – формировать bond – связь easily – легко very reactive – хорошо вступающий в реакции on the right – находящийся справа to contain – содержать common – обычный non-metal – не металл since – так как to make – делать stable – устойчивый directly – прямо to the left – слева readily – легко, быстро, с готовностью to gain – получать to make up – составлять main-group – главная группа transition metal – переходный элемент on the bottom – внизу, на дне rare metal – редкий металл to include – включать the same – те же самые to behave – проявлять себя, вести себя similar – подобный жүктеу/скачать 422,31 Kb.
