Hello everyone, in this question we need to differentiate between the following.
00:04
The first one is the atomic number and mass number.
00:09
So, the atomic number is basically the number of protons and the mass number is the number of protons plus the number of neutrons.
00:26
We can take the example here of helium.
00:32
So, the atomic number is 2 and mass number is 4.
00:41
Then we need to differentiate between the isotopes and radioisotopes.
00:46
So, isotopes are basically different form of atoms of same element whereas the radioisotope is the unstable isotope of a chemical element that can undergo the radioactive decay.
01:08
The radioisotopes are essentially radioactive whereas the isotopes do not show the radioactivity.
01:17
Then the third differentiate is that of the shell and orbit.
01:22
So, a shell is the pathway that is followed by electrons around the nucleus whereas the orbital is the mathematical function that describes the wave -like behavior of an electron.
01:46
So, shell basically gives the principal quantum number whereas the orbit gives the magnetic quantum number.
01:58
Then the next is between ionic and covalent bond.
02:02
So, ionic bond are the chemical link between two atoms that is caused by electrostatic forces or by oppositely charged ions.
02:15
In an ionic bond it has a high polarity whereas the covalent bond there is a chemical link between two atoms or ions and the electron pairs are shared amongst them and they have low polarity like oxygen.
02:36
In the ionic bond we can take the example of nacl...
