According to me
Atomic No= No.of protons or electrons in an atom.

Bala said:   1 decade ago
In a nuetral atom the atomic number is equal to no of protons and also equal to no of electrons.

Nandhu said:   1 decade ago
In an atom, no of protons are equal to the electrons. So whether it protons and electrons are sai to be correct.

Hence electron is the negative charges and neutron is the zero.

Obtion (B) is correct.

For any atom with atomic number N, atomic mass Z & no. of neutrons 'n', we have,

Atomic mass number= Z+n...(1)

So, atomic number N is given by

N=Atomic mass number - Atomic mass

=(Z+n)-Z

=n.

Which means that atomic number depends upon number of neutrons & hence 'D' should be the correct option.

Protons which determines the number of atomic number in atom.

Yes I agree with samantha.

Samantha said:   1 decade ago
Proton is right. I agree with vinay.

Vinay said:   1 decade ago
But while sharing electrons number will change.

So we take proton number only.

Ok but for meteals or non ions electrons can also be said as atomic no.
