Note: Skinny jeans are NOT the same as tight-fitting jeans â particularly the Wrangler kind. Those have been around in Western culture for a long time. Theyâre designed to fit closely to the waist and crotch. But the leg parts are flared and loose. Those tight-fitting jeans donât restrict freedom of movement.
Post. Share. Ionization Energy Definition: Ionization energy is the energy required to remove an electron from a gaseous atom or ion. The first or initial ionization energy or E i of an atom or molecule is the energy required to remove one mole of electrons from one mole of isolated gaseous atoms or ions. You may think of ionization energy as a measure of the difficulty of removing electron or the strength by which an electron is bound.
Veiw a periodic table with first ionization energies. Definition: Second Ionization Energy is the energy required to remove a second outermost electron from a ground state atom. Subsequent ionization energies increase greatly once an ion has reached the state like that of a noble gas.) As you move across a period, first ionization energy increases. WHY? - As you move across a period, the atomic radius decreases, that is, the atom is smaller. The outer electrons are closer to the nucleus and more strongly attracted to the center. Therefore, it becomes more difficult to remove the outermost electron.
