1. Read and translate the text on specialty in written form:


OCCURRENCE AND DISTRIBUTION OF THE ELEMENTS.
Comparatively few of the elements occur in the free or uncombined state in nature. Among these are oxygen and nitrogen, these exist free and are mechanically mixed together in the atmosphere. Sulphur occurs in the free state in large deposits in the neighbourhood of volcanoes. Carbon occurs free in its purest natural form, crystallized as the diamond. It also occurs in many places as graphite.
Arsenic, copper, gold, silver, platinum and mercury also occur in the free state. Although many of the elements occur in the free state in nature, they are more often found in the state of combination with other elements. Metals are usually found in metallic ores combined with one or more of the following elements – sulphur, carbon, oxygen, silicon, chlorine, fluorine, phosphorus etc.
Hydrogen and oxygen occur combined as water. They also are essential constituents of all animal and vegetables bodies. Most organic compounds contain them.
Various elements occur scattered very irregularly throughout the earth. Some are very abundant and occur widely distributed, while others are found in such minute quantities that their properties are not fully studied.
