which species is expected to have the smallest radius?
Li2+
Li-
Li+
Li
Li 2+ has lost 2 electrons.
Electrons repel each other and orbit the nucleus. If you take two away, you not only reduce the number of shells, but you also reduce the amount of repulsion. Therefore, by removing two electrons, you ar reducing the radius by two.
which species is expected to have the smallest radius? Li2+ Li- Li+ Li

Which of the following ions should have the smallest ionic radius? A) Sc 3+ B) Ca 2+ C) K+ D) Ar + E) Cl -
Which of the following species are isoelectronic with Ne? Check all that apply. mg2+ Ca Li+ Al3+ F- Na+ Li
Electron radii problem. I thought that P(-3) would have the
smallest radius because it is the same as MG, but the answer key
says CA 2+ is the smallest. Can anyone explain this?
thanks.
5. The following ions are isoelectronic, meaning that they have the same number of electrons. Which of these ions has the smallest atomic radius? (a) Ca+ (b) K (c) Cl 2-
a) Why is the Li+ radius so much smaller than the radius of the neutral Li atom? b) Why is the F- radius so much larger than the neutral F atom? b) Which transition involves the emission of less energy in the H atom, an electron moving from n=4 to n=3 or an electron moving from n=3 to n=2?
1. Out of the following, which electron will be the easiest to remove from Li, justify your answer H2, He2, Li2, Be2, B2, C2, N2, O2, F2, Ne2 2. How much energy will it take to remove that electron from Li according to Koopman's theorem?
Rank the following ions in order of decreasing radius: Li+, Na+, K+, Rb+, and Cs+. Use the periodic table as necessary. Rank from largest to smallest radius. To rank items as equivalent, overlap them.
An ion source is producing Li ions, which have charge +e and mass 9.99 x 10-27 kg. The ions are accelerated by a potential difference of 15 kV and pass horizontally into a region in which there is a uniform vertical magnetic field of magnitude B = 0.93 T. Calculate the strength of the smallest electric field, to be set up over the same region, that will allow the Li ions to pass through undeflected.
