Question

The distance between two atoms in a molecule is measured in order of angstrom
 $ \left( A \right)True \\
  \left( B \right)False \\ $

Answer 1

Hint :To solve this question, we are going to consider the process of formation of a molecule by the atoms and the distance at which the two atoms have to come to form a bond such that the molecule is formed, is considered. Such a distance should be very small which gives us the idea of order.
The bonding of two atoms requires the formation of two types of bond, first is ionic, second is covalent, ionic bond consists of sharing of electrons while the covalent consists of the overlapping. In both the cases, it is very important for the atoms to come closer.

Complete Step By Step Answer:
 In order to form a molecule, it is important that the two atoms come in a range of a very small distance, the distance between the atoms is of such a small order that we have to use a unit very small. Such a distance is taken in the order of $ {10^{ - 10}}m $ . This order, if converted into a unit, we call it angstrom. So, the measured distance of the two atoms is taken in the order of angstrom. Therefore, the option $ \left( A \right)True $ is the correct answer.

Note :
In gases, for the molecules to be formed, the atoms can be at distances as large as a meter but this is not to be confused with the normal case for the formation of an atom. The distance normally has to be as small as an angstrom only. Even the distance of order of nanometers is large for molecule formation.
