1. On the basis of Thomson’s model of an atom, explain how the atom is neutral as a whole. Ans:As per Thomson’s model of an atom, the number of electrons and the number of protons are equal in an atom. Electrons are positively charged and protons are negatively charged, hence the...
atom is bound to four different substituents as shown below. enantiomers were introduced as stereoisomers that are non-superimposable mirror images of one another. any molecule that is not superimposable on its mirror image and so exists as a pair of enantiomers is said to be chiral and to ...
It is made up of two atoms of oxygen and one atom of titanium which is the 9th most common element in the crust of the earth and it is present generally in plants and animals. In order to form titanium dioxide, the metal of titanium reacts naturally with oxygen. This oxide is commonly...
(o 3 ). ozone o3 is generated through the passage of oxygen o 2 through a high voltage potential resulting in the attachment and formation of a third oxygen atom. the molecular formula for ozone (o 3 ) was established by soret (1863) by taking the ratio of the change in volumes when...
