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.

gladu [14]

<u><em>Answer:</em></u>

  • A pure substance that contains more than one atom is called a compound.

<u><em>Explanation:</em></u>

  • Compounds are formed by combination of atoms by a fixed ratio. They have their own characteristic features.
  • Pure substances are further broken down into elements and compounds. A compound can be destroyed by chemical means. It might be broken down into simpler compounds, into its elements or a combination of the two.

<u><em>Example </em></u>

  • H2SO4 which  is formed by combination of three different atoms like H, S and O.
