WebThe protons and neutrons are found in the nucleus at the centre of the atom. The nucleus is very much smaller than the atom as a whole. The electrons are arranged in shells … WebMar 26, 2016 · This is known as the Uncertainty Principle. The quantum mechanical model of the atom uses complex shapes of orbitals (sometimes called electron clouds ), volumes of space in which there is likely to be an electron. So, this model is based on probability rather than certainty. Four numbers, called quantum numbers, were … WebApr 6, 2024 · Thus an atom can also be defined as the simplest structural unit of an element that retains all its properties.
