Elements are the building blocks of nature. Water, for example, is a compound composed of two ingredients: hydrogen and oxygen elements. Each element is a pure substance that cannot be split up into any simpler pure substance. The smallest particle of an element that can exist is an atom. An atom is made up of subatomic particles.

Water, for example, is a compound that has two hydrogen atoms and one oxygen atom in it . Its chemical formula is H 2O. When sodium (Na) combines with chlorine (Cl) you get a compound called salt (NaCl). Carbon and hydrogen atoms form methane, or natural gas (CH 4).
Elements and Compounds :
An element can combine with one or more other elements to form compounds, of which there are millions. For example, one of the bestknown compounds is water, written chemically as H 2 0, which means that water is made of two atoms of hydrogen combined with one of oxygen.

Some other examples of mixtures include blood (a mixture of blood cells, platelets and plasma), steel (a mixture of iron and other materials) and the gold that is used to make jewellery. The gold in jewellery is not pure gold but is a mixture of metals.
Elements and Compounds
gold atoms. Compounds In a compound, the atoms of one element are joined tightly to the atom or atoms of another element. This means that a compound is made up of different types of atoms bonded together. A compound has very different properties compared with the elements from which it is made. For example, the compound sodium chloride (table salt) is very different from the elements sodium .

Jul 09, 2014· Chemists succeed in isolating carbongold compound of "amazing stability". The researchers first shielded the gold and carbon from its environment by surrounding them with lowreactive, spacefilling chemical groups. Then the two elements were bonded in a carefully planned step – and so the Au=C fragment was "caught" in the gold carbene complex.

Transition metals are defined as those elements that have (or readily form) partially filled d orbitals. As shown in Figure 1, the dblock elements in groups 3–11 are transition elements. The fblock elements, also called inner transition metals (the lanthanides and actinides), also meet this criterion because the d orbital is partially occupied before the f orbitals.
