Atomic Number and Mass Number | Chemistry

In this animate lecture, I will teach you the concept of atomic number and mass number. You will also learn that how can we calculate atomic number and mass number.

Q: What is atomic number?
Ans: Atomic number is defined as the total number of protons present in the nucleus of an atom. Atomic number is sipmly the number of protons present in an atomic.
For example, the atomic number of Hydrogen element is 1. The atomic number of Carbon element is 6.

Q: What is mass number?
Ans: Mass number is defined as the sum of total number of protons and neutrons present in the nucleus of an atom. Mass number or atomic mass is equal to the total number of protons and neutrons present in the nucleus.
For example, the mass number of Car is 12 units. Mass number of an Oxygen is 16 units.

I yesterday saw his channel, I was so happy to have a good and useful channel, thankyou u r the real teacher ❤

[peace]

P=8
E=8
N=?

Solution: Substrate Z(Atomic No.) from A(Atomic Mass)

16-8=8

Answer: N=8

Sir tnx for ur lecture u explains soo well I don't know even basics of Chem but this video helps me alot THANK U SO MUCH SIR

[shoaibphysicswallah]

Thanks dear sir!
Your question answer is=in O=>Z=8, proton=8, electron=8 and A=16 and N=8.

I'M Tanzanian sir, but I enjoy you lecturer, may God bless you inshallah

[mindthoughts]

8 protons
8 neutrons
8 electrons
So easy Thank you sir ☺️

[krishgamer]

Thanks you so much bro for a nice explanation ❤️❤️

[DivyaRoy-npve]

Sir your explanation is as beautiful as Sachin sir's straight drive

[vivektogati]

P=8
E=8
N=16-8=8
Thanks for the clear explanation 👏

[sartajalam]

Really your concept are very understanding

[manjulata]

Thankq so much sr to undrstand by easy way thankq

[KeziaTiwaaBaafi]

I don't understand why number of neutrons is higher than protons in sodium(Na) as compared to carbon(C) and helium(He)

[Deepikaaaaa]

P=8
E=8
N=8(16-8=8)
Thankyou for clearing the topic🤍

UNCLE I THINK JUST ABOUT THIS ONLY YOU PUTTING THIS VIDEO THANK YOU 👍🏻👍🏻👏🏻👏🏻👌🏻👌🏻🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏

Z=8
No.of P=Z=8
No.of E=No.of P=8
No.of N=A-Z, 16-8=8
