WebWhat’s in an Atom? • Atoms are the building blocks of matter. • Atom is mostly empty space. Most of the mass of the atom is found in the nucleus. • If the nucleus was 1 cm across, the whole atom would be the size of a football field. Protons and neutrons are found in the nucleus- the center of the atom. The nucleus is very small compared to the overall size of …
WebRemember, the 'size' of an atom has nothing to do with the size of the nucleus. It has to do with the size of the valence shell (which itself is not well-defined*). So, if we neglect change in electrical attraction, the size should stay the same—a shell is a shell and it need not 'expand' to accomodate electrons. reattach my cameraWebFeb 23, 2016 · Atomic size INCREASES down a Group, but DECREASES across a Period.
