The number of electrons in an electrically-neutral atom is the same as the number of protons in the nucleus. However, this assumes the atom to exhibit a spherical shape, which is only obeyed for atoms in vacuum or free space. Copyright © 1996-2012 Yinon Bentor. Atomic number denotes the number of protons or electrons in an atom. As the most electronegative element, it is extremely reactive: almost all other elements, including some noble gases, form compounds with fluorine. Only fluorine-19 is stable and naturally occurring; therefore, fluorine is a monoisotopic and mononuclidic element, and only artificially produced fluorine isotopes have mass numbers other than 19. A Fluorine atom, for example, requires the following ionization energy to remove the outermost electron. Non-Metals The atomic mass is the mass of an atom. a.

There are related clues (shown below). Electron affinities are more difficult to measure than ionization energies. Which of the following characteristics is similar for fluorine and iodine? Note that, each element may contain more isotopes, therefore this resulting atomic mass is calculated from naturally-occuring isotopes and their abundance. Isotopes are nuclides that have the same atomic number and are therefore the same element, but differ in the number of neutrons. Which atom has 28 protons? Doing a Radiation with sufficient energy to create ions by physically removing electrons from neutral atoms is referred Density is defined as the mass per unit volume. Number of protons . The total electrical charge of the nucleus is therefore +Ze, where e (elementary charge) equals to 1,602 x 10-19 coulombs. This page was created by Yinon Bentor.
