WebAug 30, 2024 · 7.11: Electronegativity. The ability of an atom in a molecule to attract a shared electron pair to itself, forming a polar covalent bond, is called its electronegativity. The negative side of a polar covalent bond corresponds to the more electronegative element. Furthermore the more polar a bond, the larger the difference in … http://www.jukenmemo.com/chemistry/inorganic/halogen/

WebIn 1913, the English physicist Henry Moseley developed the concept of atomic numbers. He correctly identified the atomic number with which of the following? 1. the number of protons and neutrons in the nucleus of an atom. 2. the atomic weight of an atom. 3. the number of protons in the nucleus of the atom and the number of electrons in the atom. WebVerified answer. physics. An astronomical unit (\mathrm {AU}) (AU) is equal to the average distance from Earth to the Sun, about 92.9 \times 10^6 \mathrm {mi} 92.9× 106mi.
