Which of the following may contribute to the increased radius of an anion compared to parent atom? select all that applies.
-
Additional electrons lead to more electron-electron repulsion, which will increase the average distances of all the outer orbitals from the nucleus.
-
Additional electrons may need to occupy higher-energy orbitals, which are farther from the nucleus than the lower-energy orbitals.
-
The charge of the nucleus decreases.
-
None of the above

Question 9 Which of these statements is false? An anion is always larger than its parent neutral atom. The first electron affinity is always a large negative value. First ionization energy decreases in going down a column (group). Second ionization energies are always larger than first ionization energies. Atomic size decreases in going from left to right across a row (period).

In questions 2-4, you may use radius comparisons as given information. IONIZATION ENERGY. Ionization energy refers to energy required to remove an outer electron from an isolated atom. The energy tends to be less for elements with weaker attractions to the nucleus or higher initial energy levels. The general trend is for lower energy for elements lower in columns and higher energy from left to right across rows of the periodic table. There are some notable exceptions. Explain why: 2....

Which of the following events may occur when IR radiation is absorbed? (true or false) -Intra-molecular bond angles are changed. -Vibrational amplitudes of bonds are increased. -Relative electron spins are changed. -Bonding electrons are promoted to higher energy molecular orbitals. -More intense IR absorptions occur for those bonds having greater dipole moment changes with bond lengthening in a vibration.

Could you please give me answers for these ? thanks 1. Atomic radius decreases as we move from left to right in the periodic table. Which of the following is the BEST explanation for this trend? a. The electrons in the valence shell increase in number and thus interact more with one another as we move from left to right. b. There is more shielding of the inner electrons as we move from left to right. c. The electrons in...

Bohr Atom 01 Due this Tuesday, Apr 24 at 11:45 am (EDT) The Bohr Model of the hydrogen atom proposed that there were very specific energy states that the electron could be in. These states were called stationary orbits or stationary states. Higher energy states were further from the nucleus. These orbits were thought to be essentially spherical shells in which the electrons orbited at a fixed radius or distance from the nucleus. The smallest orbit is represented by n=1,...
