Describe the Size of an Atom
Size of an atom. Each electron has a negative charge -1 equal to the positive charge of a proton 1. Atomic Size Introduction To Chemistry It represents the mean distance from the nucleus to the boundary of the surrounding cloud of electrons. . Compared with the overall size of the atom the nucleus is even more minute. The protons and neutrons make up the nucleus the center of the atom and the electrons fly around the. Atoms vary by size but consider a hydrogen atom. The nucleus of an atom is about 10-15 m in size. This means that if the nucleus were a typical pea then the atom would be about the size of a baseball field. Every atom includes electrons and a nucleus where protons and neutrons reside. 74 rounds up to 10. Protons and neutrons have approximately the same mass about 167 10-24 grams which scientists define as one atomic mass unit amu or one Dalton. Dynamic Science I The tendency of an atom to att...
