Okay, so we should keep in mind that in the atomic structure, so atom consists of nucleus in the center.
00:08
This nucleus consists of further neutron and proton.
00:11
Neutron carry no charge, they are neutral, and protons carry positive charge.
00:18
The electrons are revolving around the nucleus and those electrons carry negative charge.
00:25
Okay, now, first of all, in the first blank we have.
00:30
Given so we have given that location is a right so for location a atomic mass 1 .0 atomic mass unit okay so that is approximate mass okay let me write again approximate mass we have given now see on the basis of this information name so that should be proton symbol this will be p positive charge so in multiples of like e okay so this is 1 .6 10 raised to power minus 19 that with positive okay plus sign so as i told you that the proton lies in the center of nucleus, okay, and mass is one atomic mass unit.
02:02
Actually, proton is what? proton is actually considered for the h -positive ion, okay, and hydrogen ion here.
02:12
So that is the proton, and hydrogen itself has the mass of one.
02:17
Okay, proton, actually, i should say especially for proton, which has mass one, okay? having atomic number one also so this is called proton now moving on to next second we have given symbols and that is e minus okay now on the basis of this the name so this will be electron then okay symbol is done charge charge will be minus 1 .6 multiplying 10 raise to power minus 90.
03:08
Okay...
