Detailed explanation-1: -The mass of the atom is concentrated in the nucleus (protons and neutrons are about 2000 times as heavy as electrons). 2. The atomic number (the number of protons) determines which element an atom is.
Detailed explanation-2: -The nucleus of an atom contains the protons and neutrons, which are much more massive particles than the electrons found orbiting outside the nucleus. As a result, the mass of an atom is concentrated in the nucleus.
Detailed explanation-3: -What is the model of the atom proposed by Ernest Rutherford? The atom, as described by Ernest Rutherford, has a tiny, massive core called the nucleus. The nucleus has a positive charge. Electrons are particles with a negative charge.
Detailed explanation-4: -Mass of an atom is concentrated inside the nucleus of the atom. Medium.
