first ionisation energy - correct answer the energy required to remove one electron from each atom in a mole of gaseous atoms to form one mole of gaseous 1+ ions second ionisation energy - correct answer the energy required to remove one electron from each ion in one mole of gaseous 1+ ions to form one mole of gaseous 2+ ions factors affecting ionisation energy - correct answer at...

Atomic Radius, Nuclear Charge, Electron Shielding - What are the 3 things that affect first ionisation energy? Increase. More protons- stronger attraction. Not much extra shielding. - What is the general trend in ionisation energy across periods? And why? Decrease due to increased attraction between electrons and nucleus. - What is the trend in atomic radius across a period? Increase due to metallic bonds getting stronger. - What is the trend in boiling points across metals? Silicon. Stro...

What is the correct definition of "emission"? correct answer: The release of energy in the form of a photon as an electron transitions to a lower energy level What is the correct definition of an "excited state"? correct answer: All energy states other than ground state until ionisation threshold (E=0). How is the energy of a particle with restricted motion best described? (ie. an electron bound to an atom) correct answer: There are an infinite number of discrete energies possible f...
