Answer:

Size of cation is lower than neutral atom because as a particular atom looses electron, no of proton become more than no of electron and attraction forces increases so radius decreases.

What is the number of electrons shared between the atoms in a I2 molecule
vova2212 [387]

The number of electrons shared between the atoms in a I₂ molecule is two (2).

Explanation:

An iodine atom has 53 electrons and its electron configuration is;

2. 8. 8. 18. 17

  1s²2s²2p⁶3s²3p⁶4s²3d¹⁰4p⁶5s²4d¹⁰5p⁵

Note that the outermost p shell has 5 electrons while it can accommodate a maximum of 6 for stable electron configuration. Therefore an Iodine atom needs one (1) electron to acquire nobility. Two Iodine atoms will, therefore, share two electrons (each from one of their p sub-shell ) by covalent bonds to form I₂
