High, we are asked to compare the size of a catane and an anion with the size of the neutral atom.
00:07
Now a catine is formed when a neutral atom loses an electron.
00:12
Thus a catane is always positively charged.
00:16
An anion is formed when a neutral atom gains an electron.
00:21
And thus, as it has an extra electron, it is always negatively charged.
00:25
Now, what are the factors that define the size of an atom? the central of the atom is a nucleus.
00:32
It contains some protons which are positively charged and neutrons.
00:36
These are the orbits in which the electrons revolve.
00:40
The protons attract the electrons and these electrons also repel each other.
00:45
So these are the forces of attraction and repulsion which determine the final size of an atom.
00:52
Now, suppose in a neutral atom we have two electrons in the first tail and the two electrons in the same.
00:59
Second shell.
01:00
When a catane is formed, so suppose this is a.
01:03
When a catane is formed, it loses one electron.
01:08
So this electron is gone...
