To solve this problem, we need to analyze each statement and determine which are correct.$\\$A. Atoms of all elements are composed of two fundamental particles.$\\$This statement is incorrect. Atoms are composed of three fundamental particles: protons, neutrons, and electrons.$\\$B. The mass of the electron is $9.10939 \times 10^{-31}$ kg.$\\$This statement is correct. The mass of an electron is indeed $9.10939 \times 10^{-31}$ kg.$\\$C. All the isotopes of a given element show the same chemical properties.$\\$This statement is correct. Isotopes have the same number of protons and electrons, which determine chemical properties.$\\$D. Protons and electrons are collectively known as nucleons.$\\$This statement is incorrect. Nucleons refer to protons and neutrons, not electrons.$\\$E. Dalton’s atomic theory regarded the atom as an ultimate particle of matter.$\\$This statement is correct. Dalton's atomic theory considered atoms as indivisible particles.$\\$Now, let's evaluate the options:$\\$Option 1: A, B, and C only$\\$• A is incorrect, so this option is incorrect.$\\$Option 2: C, D, and E only$\\$• D is incorrect, so this option is incorrect.$\\$Option 3: A and E only$\\$• A is incorrect, so this option is incorrect.$\\$Option 4: B, C, and E only$\\$• B, C, and E are all correct, so this option is correct.$\\$Therefore, the correct answer is Option 4.
