The isotope of uranium used as a fuel in nuclear reactors and carbon used in radiocarbon dating are

In response to a question,a student stated that in an atom,the number of protons is greater than the number of neutrons,which in turn is greater than the number of electrons. Do you agree with the statement? Justify your answer.

If the number of electrons in an atom is $8$ and the number of protons is also $8$,then $(i)$ what is the atomic number of the atom? and $(ii)$ what is the charge on the atom?

Is it possible for the atom of an element to have one electron,one proton,and no neutron? If so,name the element.

Which of the following statements are true for an element?
$(i)$ Atomic number $=$ number of protons $+$ number of electrons
$(ii)$ Mass number $=$ number of protons $+$ number of neutrons
$(iii)$ Atomic mass $=$ number of protons $=$ number of neutrons
$(iv)$ Atomic number $=$ number of protons $=$ number of electrons

Explain with examples $(i)$ Atomic number,$(ii)$ Mass number. Give any two uses of isotopes.
