Question
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
Solution
The correct statement about the isotopes of an element is B. They have the same electron arrangement.
Here's why:
A. They have the same mass number - This is incorrect. Isotopes of the same element have different mass numbers due to the different number of neutrons.
B. They have the same electron arrangement - This is correct. Isotopes of an element have the same number of protons and therefore the same number of electrons. This means they have the same electron arrangement.
C. They have more protons than neutrons - This is incorrect. The number of protons and neutrons can vary in isotopes of the same element.
D. They have the same numbers of protons and neutrons - This is incorrect. Isotopes of the same element have the same number of protons but different numbers of neutrons.
