Question

From your knowledge about the distribution of electrons in their shells and from the atomic number (in parentheses), indicate the most likely charge on the ion when this atom forms an ion. (Remember the 2-8-18 shell distribution.) Hydrogen (1)

Answer 1

Answer:

$H^{-}$ or $H^{+}$

Explanation:

General electron shell distribution id 2 - 8 - 18

Now hydrogen has 2 electrons in its outermost shell. The only it can become a hydrogen ion is either by gaining one electron or by loosing  one electron. Hydrogen atom looses one electron to become a positively charged ion called the cation and can gain one extra electron to become a negatively charged ion called the anion.

Answer 2

The answer is +1, hope this helps.
