The main characteristic properties of covalent compounds are: 1. The covalent compounds do not exist as ions but exist as molecules because of weak inter molecular force. 2. The covalent compounds have lower melting and boiling points 3. Covalent compounds are generally insoluble or less soluble in ...

Two types of covalent bonds are formed depending upon the electro negativity of the combining elements. 1. Non-polar covalent bond 2. Polar covalent bond Non-polar covalent bond During the Formation of a covalent bond between two atoms which belong to the same element, the pair which is shared will lie in ...

A covalent bond is a form of chemical bonding that is characterized by the sharing of pairs of electrons between atoms, and other covalent bonds. In short, the attraction-to-repulsion stability that forms between atoms when they share electrons is known as covalent bonding. The concept of ...

The factors which influence the formation of an ionic bond between a metal and non-metal are discussed below: 1. Ionization Energy: The amount of energy required to remove (to infinity) the outermost electron i.e. loosely bound electron in the atom when the gas atom is isolated ...

In this type of bond, the outer atomic shell of one atom has a vacancy which allows addition of one or more electrons. These newly added electrons potentially occupy a lower energy-state (effectively closer to more nuclear charge) than they experience in a different atom. ...

A chemical bonding is an attraction between atoms or molecules and allows the formation of chemical compounds, which contain two or more atoms. It is caused due to redistribution of electrons in the outer shells. The redistributions take place either by the process of electron ...

92U238 ------> 90Th234 + 2He4 + Q The exact mass of 92U238 isotope = 238.1249 a.m.u. and that of 90Th234 = 234.1165 a.m.u. The exact mass of 2He4 = 4.0039 a.m.u. Where, a.m.u. is Atomic Mass Unit. The value of Q can ...

2 1H1 + 2 0n1 ----->2He4 Check whether the reaction is exoergic or endoergic? The exact mass of 1H1 isotope = 1.0081 a.m.u. and that of 0n1 = 1.0086 a.m.u. The exact mass of 2He4 = 4.0039 a.m.u. Where, a.m.u. is Atomic Mass Unit. The value of Q can be ...
