Isotopes contain?(i) Same nuclear charge, but different mass number.(ii) Different nuclear charge, but same mass number.(iii) Same nuclear charge and same mass number(iv) Same number of neutrons.

Two atoms are isotopes if they havea) different atomic numbers.b) the same mass number, but different atomic numbers.c) the same number of protons and neutrons.d) the same number of electrons, but a different number of neutrons.e) the same atomic number, but a different mass number.

Isotopes of an element have different mass numbers. Complete the sentence to explain why.  Because they have different numbers of:neutronsprotonselectrons

Which statement is correct about the isotopes of an element?A. They have the same mass numberB. They have the same electron arrangementC. They have more protons than neutronsD. They have the same numbers of protons and neutrons

Isotopes of the same element are different from one another in thatMultiple Choicethey have a different number of protons.they have a different number of neutrons.they have a different number of electrons.they are a different element.only one of the isotopes is matter.

Which statement about the isotopes of an element is correct?A. They have the same mass number.B. They have a different atomic number.C. They have the same chemical properties.D. They are located in different places in the periodic table
