Answer:

Ions are atoms with a positive or negative charge.

Explanation:

Ions are atoms or molecules that, when subjected to the phenomenon of ionization, gain or lose electrons, ceasing to be neutral and acquiring an electric charge.

The charge that atoms or molecules possess can be positive —if it has lost electrons— or negative when it acquires electrons. The negatively charged particle is called anion, and when it is positively charged cation.

The other options are not correct because of:

There are usually as many or more neutrons than protons.
Uncharged atoms are neutral.
The number of protons or neutrons does not affect the electric charge of the atom.
Atoms that joined in fixed proportions can form molecules.

AlladinOne [14]

Answer:

Explanation:

Oxygen is needed to support life and some metabolic processes in microorganisms especially aerobic organism.

The presence of oxygen in the container gives them the opportunity to carry out there metabolic activities thereby enhancing there growth and multiplication.

Hence, to limit the growth of aerobic bacteria or fungi, and also to prevent the evaporation of volatile components that is available in the content oxygen is withdrawn this help extend the shelf life of the produce to be stored.
