QUESTION:
Estimate the relative sizes of the following species: \(\mathrm{Li},\mathrm{\ Li}^+,\mathrm{\ Li}^-\).
ANSWER:Step 1 of 2
Here, we are asked to estimate the relative sizes of the given species.
First, we shall consider that almost all the volume in an atom or monoatomic ion is occupied by the electrons and we determine the number of electrons in each species and determine their size according to the number of electrons.
Generally, for any element, the anion is the largest, the atom is second largest, and the cation is the smallest. The size of an atom depends on the outer boundary of the electrons.
