molecules and compounds

Molecules of Compounds - A molecule of a compound consists of two or more atoms of different elements joined together in a fixed ratio. Examples: CuSO 4 contains Cu - 1 atom, S - 1 atom, O - 4 atoms A chemical formula represents the composition of a mole..

A molecule of a compound consists of two or more atoms of different elements joined together in a fixed ratio. Examples: CuSO 4 contains Cu - 1 atom, S - 1 atom, O - 4 atoms A chemical formula represents the composition of a molecule of the substance in terms of the sy..

It is smallest particle (of an element or compound), which is capable of independent existence. Molecules are formed by combination of atoms. Molecules are formed by combination of atoms If the molecule is made up of atoms of the same element it is said to be..

Carbon atom has four electrons in its outermost shell. Thus, it requires four more electrons to acquire a stable noble gas configuration. Each of the hydrogen atoms has only one electron in its outermost shell and requires one more electron to complete its outermost shell (to acquire He configura..

Carbon atom has four electrons in its outermost shell and hydrogen atoms have only one electron in its outermost shell. Carbon share one of its electrons with hydrogen to form a single bond each. Each carbon then requires three more electrons to acquire a stable configuration of the nearest noble..

Atoms and Molecules - Laws of Chemical Combination With the development of more scientific ideas on elements, compounds and mixtures, people began to probe into how and why substances react. French chemist A. Lavoisier laid the foundation to the scientific investigation of matte..

Formation of Molecule Atoms of most of the elements do not exist independently. They either form molecules or ions. An atom having a charge on it is called an ion. When an atom loses or gains charge, it gets converted into a positively or negatively charged ion respectively...

Atoms and Molecules - Summary The law of conservation of mass states that the masses of the reactants and products remain unchanged. The law of constant proportions states that all pure specimens of a compound always contain the same elements combined together in the same propor..

such as linear, triangular, square planar, pyramidal, octahedral etc. The shape of a molecule affects its chemical and physical properties. For instance, some of the unique properties of water are due to the angular shape of its molecule (H 2 O). The stability and the self-repli..

Chemical Formulae Every chemical substance is known by a specific name. But these names can sometimes be cumbersome, confusing and not provide sufficient information about its chemical composition. To overcome this, each chemical compound is represented by a chemical formula that give..
