Google Answers: atoms What Two Factors Determine the Atomic Radius of ... - Synonym Which element has the smallest atoms? | Socratic What is the difference between H+ ion and an electron? - Quora Tue Nov 04 2014 · The other trend of atomic radius or atom size occurs as you move vertically down an element group. This direction increases the size of the atom . Again this is due to the effective charge at the nucleus . This time even though the number of protons increases by a lot the electron valence shells do not. The size of an atom can be estimated by measuring the distance between adjacent atoms in a covalent compound . The covalent radius of a chlorine atom for example is half the distance between the nuclei of the atoms in a Cl 2 molecule. The covalent … Assuming atoms have a spherical shape the radius of the sphere describes the size of the atom . The atomic radius of a chemical element is a measure of the size of its atoms . It represents the mean distance from the nucleus to the boundary of the surrounding cloud of electrons. So the takeaway message is that atom size depends on the environment the atom is in since things like pressure temperature and other atoms can drastically affect atomic size. The atoms size is also determined by electrons that are hard to pin down so edges of things get very fuzzy at the atomic scale .
