Question

An oxygen atom picks up two additional, free floating electrons. Is the charge of the newly formed oxygen ion positive, negative or neutral?

Answer 1

Answer:The newly formed oxygen ion is negatively charged.

Explanation:

Cation : These are species of ions which carries positive charge that is number of protons are greater than the number of electrons.

Anion:These are species of ions which carries negative charge that is number of electrons are greater than the number of protons.

$O+2e^-\rightarrow O^{2-}$

When an oxygen atom gains two electrons it develops the charge of negative charge and forms anion.

Answer 2

I  believe it would be negative as electrons carry negative energy

hope this helps :)
