formation of water molecules

Each oxygen atom has six electrons in its valence shell. Thus, it requires 2 more electrons to achieve the nearest noble gas configuration. This is achieved by sharing two pairs of electrons by the two oxygen atoms as shown below: ..

Nitrogen atom has five electrons in its valence shell. Thus, it requires three more electrons to acquire a stable configuration of the nearest noble gas (neon). This is done by mutually sharing three pairs of electrons as shown below: ..

Two hydrogen atoms mutually share one electron each with an atom of oxygen to form a water molecule (Fig. 3.8). Note ..

Chlorine atom has seven valence electrons. Thus, each Cl atom requires one more electron to acquire the nearest noble gas configuration (Ar:2, 8, 8). They do this by mutual sharing of one pair of electrons as shown below...

With a considerable decrease in the earth's temperature over thousands of years, the atoms of different elements came together at random and formed inorganic molecules. Since the lighter elements (hydrogen, oxygen, carbon and nitrogen) were the most abundant in the outermost layer, their ..

Sometimes, two or more stable molecules combine to form a molecular complex. In a complex molecule, the constituent molecules are held together by a 'coordinate bond'. One typical example involves the molecules of NH 3 and BF 3 . The electron dot structures..

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 respectivel..

Water is the most abundant compound in the vast majority of cells. It forms about 60 to 90% of the total chemical content of the cell. Water accounts for about 65% of the chemical composition in the human body. In a jellyfish, the water content in the body is more t..
