Somewhere between 1 & 8 (unless ionised - could have 0). Which atom are we talking about here? Rule of thumb (not including Lanthanide & Actanide series) - Find which column it is in on the Periodic Table of elements and that's how many electrons it will have in it's (non-ionised) state.

How many electrons in the outer shell does hydrogen ion have?
The hydronium ion has NO(zero) electrons in its outer structure It can be thought of as a 'single proton'. However, it usually combines/attached to another molecule, such as water making the hydronium ion ' H3O^(+) '. or an ammonia molecule making the ammonium ion ' NH4^(+) ' . This is because these two molecule have lone pairs of electrons in their outer energy shells to which the 'proton' can attach.
How many outer shell electrons does iodine have?
The outer most electron shell of iodine atom contains 7 electrons.

The inner electron shell of carbon holds two electrons the outer ones hold up to 8 electrons. How many electrons have in its outer shell?
Carbon has four electrons in its outer shell. The electron configuration of carbon is 1s² 2s² 2p², where the two electrons in the inner shell (1s) are not counted toward the outer shell. Therefore, in the outer shell (2s and 2p), carbon has a total of four electrons.
How many electron pairs are in the outer shell of nitrogen?
Nitrogen has 5 electrons in its outer shell, so there are 3 electron pairs in the outer shell of nitrogen.
What is the electron called when the electrons in the outer shell of atoms?
These are the valence electrons.
