Cupric ion formula

Copper is a chemical element ; it has symbol Cu from Latin cuprum and atomic number It is a soft, malleable, and ductile metal with very high thermal and electrical conductivity. A freshly exposed surface of pure copper has a pinkish-orange color. Copper is used as a conductor of heat and electricity, as a building material , and as a constituent of various metal alloys , such as sterling silver used in jewelry , cupronickel used to make marine hardware and coins , and constantan used in strain gauges and thermocouples for temperature measurement. Copper is one of the few metals that can occur in nature in a directly usable metallic form native metals. This led to very early human use in several regions, from c. Thousands of years later, it was the first metal to be smelted from sulfide ores, c. In the Roman era , copper was mined principally on Cyprus , the origin of the name of the metal, from aes cyprium metal of Cyprus , later corrupted to cuprum Latin. Coper Old English and copper were derived from this, the later spelling first used around Commonly encountered compounds are copper II salts, which often impart blue or green colors to such minerals as azurite , malachite , and turquoise , and have been used widely and historically as pigments. Copper used in buildings, usually for roofing, oxidizes to form a green patina of compounds called verdigris. Copper is sometimes used in decorative art , both in its elemental metal form and in compounds as pigments.

Up until now, we have looked at elements that form ions with fixed charges. By fixed charge, we mean that we can always predict the charge on the ion. An oxide ion, for example, always has a charge of It is impossible for oxygen to form an ion with a -1 charge or a -3 charge. Many metals, on the other hand, form ions that have variable charges. Saying an ion has variable charges means that the same element can form ions with different charges. The large majority of transition metals form ions with variable charges. There is no need to memorize the charges of metals that form ions with variable charges, as the charges may be identified by using Roman numerals.

In ordinary chemical reactions, the nucleus of each atom and thus the identity of the element remains unchanged. Electrons, however, can be added to atoms by transfer from other atoms, lost by transfer to other atoms, or shared with other atoms. The transfer and sharing of electrons among atoms govern the chemistry of the elements. During the formation of some compounds, atoms gain or lose electrons, and form electrically charged particles called ions Figure 2. You can use the periodic table to predict whether an atom will form an anion or a cation, and you can often predict the charge of the resulting ion. Atoms of many main-group metals lose enough electrons to leave them with the same number of electrons as an atom of the preceding noble gas. For example, a neutral calcium atom, with 20 protons and 20 electrons, readily loses two electrons.
