Answer:
5. gains two electrons.
Explanation:
In order to determine the most stable monoatomic ion of oxygen, we need to consider the octet rule: atoms will gain, lose or share electrons to complete their valence shell with 8 electrons.
Oxygen is in the Group 16 in the Periodic Table, so it has 6 valence electrons. Therefore, it will gain two electrons to have the electron configuration of the closest noble gas.
The relation between the elements electro negativity, atomic radius, and ionization energy levels.
Answer:
The atom that loses the electrons becomes a positively charged ion, while the one that gains them becomes a negatively charged ion
Methane composes most of the natural gas.
