Question

How to find the atomic mass of any atom? If it can be found by adding the number of protons and neutrons, how to find the number of protons and neutrons? Please explain in detail...

Answer 1

Hy


Here is the answer

To calculate the atomic mass of a single atom of an element, add up the mass of protons and neutrons.



Example: Find the atomic mass of an isotope of carbon that has 7 neutrons. You can see from the periodic table that carbon has an atomic number of 6, which is its number of protons.


To find the number of neutrons, you will need to subtract the atomic number from the atomic mass.

Remember that the atomic number is the same as the number of protons, which you have already identified.



Hope helped

Answer 2

Refer periodic table and as u would be knowing that atomic no. is no. of electrons present in that element but no. of electrons=no. of protons now u got no. of protons . In ur question there must be mass no. If it's not given u have to refer periodic table and by subtracting no. of protons from mass no. u will get no. of neutrons.
If any other doubt plz ask
hope you understood.
