Question

How does adding an atom affect the position of existing atoms and lone pairs?

Answer 1

Changes the geometry by decreasing the bond angles.

Step-by-step explanation:

Before delving into the solution to the question, let us define few terms relating to the question.

ATOMS:

Atoms are said to be the smallest unit of a matter, although it has been proved that atoms contains particles such as proton, neutron and electrons. The three(that is proton, neutron, and electrons) are called the subatomic particles.

LONE PAIR:

Lone pairs are valence electrons pairs and they are found at the outer part of the atom shell.

Bond pairs: are pairs of electron responsible for bondings between atoms.

So, let us go back to the question. The electrons on the lone pairs and that of the bond pairs repels and then comes the addition of another atom. Upon this addition of atoms, strain will occur and they have to come closer, also in order to overcome this, the geometry has to change too from its original to the new one.

Answer 2

Adding an atom affect the position of existing atoms and lone pairs by changing the geomertry and changing postion of the lone pairs and atoms so that they are furthest apart. Hope this answers the question. Have a nice day.
