this (1) element is a good conductor of both electricity and heat. in chemistry, this (ancient greek métallon, μέταλλον) is an element or alloy that (2) electricity. in this element, atoms readily lose electrons to form positive ions. those ions are surrounded by delocalized electrons, which are responsible for the conductivity.
metals occupy most of the periodic table, while non-metallic (3) can only be found on the right-hand-side of the (4) table of the elements. a diagonal line drawn from boron (b) to polonium (po) separates the metals from the non-metals. most elements on this line are metalloids, sometimes called semiconductors. this is due to the fact that these elements have electrical (5) common to both conductors and insulators (elements that don’t carry electricity). elements to the lower left of this division line are called metals, while elements to the upper right of the division line are called ( .
metals are very corrosive – they (7) in contact with water. painting (or any other form of covering) is a good way to prevent their corrosion.
metals in general have high electrical conductivity, the ability to be deformed under stress. optically speaking, metals are (8) (that means ‘not clear’), shiny and lustrous. the large number of free electrons in any typical metallic element or alloy is responsible for the fact that they can never be categorized as transparent (9) .
The list of the tallest buildings in Russia includes skyscrapers and high-rise buildings with a height of 130 meters or more. For residential buildings, the height of which is unknown, but the number of storeys is known, the total height is calculated using the formula recommended by the specialists of the Council for High-Rise Buildings and the Urban Environment: for residential buildings and hotels, the floor height is taken equal to 3.1 m, for office buildings - 3.9 m, for multifunctional - 3.5 m [1]. Accordingly, the listing criterion for buildings with unknown heights is as follows: 42 floors for residential buildings, 37 floors for multifunctional buildings, 33 floors for office buildings.
перевод:Список самых высоких зданий России включает небоскрёбы и высотные здания высотой 130 и более метров. Для жилых зданий, высота которых неизвестна, но известна этажность, общая высота вычисляется по формуле, рекомендуемой специалистами Совета по высотным зданиям и городской среде: для жилых зданий и отелей высота этажа принимается равной 3,1 м, для офисных — 3,9 м, для многофункциональных — 3,5 м[1]. Соответственно, критерий включения в список для зданий с неизвестной высотой является следующим: 42 этажа для жилых зданий, 37 этажей для многофункциональных, 33 этажа для офисных.
Breakfast in the UK
One of the most famous dishes in the UK is the ‘full English’ or ‘fry-up’. It’s made up of eggs, bacon, sausages, baked beans and toast, and can also include black pudding, fried mushrooms and tomatoes! A full English breakfast takes a lot of time to cook and it’s quite unhealthy to eat every day, so a lot of British people only eat it at the weekend. On weekdays, most people eat something lighter for breakfast, like a bowl of porridge or breakfast cereal. Another popular choice is to eat buttered toast with jam or marmalade. No English breakfast is complete without a cup of tea!
