Isotopes are:
A. Atoms of an element with similar chemical properties but different atomic masses.
B. Atoms of different elements with similar chemical properties but different atomic masses.
C. Atoms of an element with different chemical properties but same atomic masses.
D. Atoms of different elements with different chemical properties but same atomic masses.
Answer:A
Isotopes are:
A. Atoms of an element with similar chemical properties but different atomic masses. B. Atoms of different elements with similar chemical properties but different atomic masses. C. Atoms of an element with different chemical properties but same atomic masses. D. Atoms of different elements with different chemical properties but same atomic masses.
Explanation: Isotopes are the atoms of some element which have same atomic number but different mass number. They have same atomic number, same number of protons, same number of electrons and, same number of valence electrons. Valence electrons are responsible for the chemical properties of an element. Since isotopes of an element have same number of valence electrons. So they will have similar chemical properties.
