Can molecules made from the same atom form ionic bonds. why?

Considering the definition of ionic bond, molecules cannot form ionic bonds from the same atom because ionic bonds form when atoms with opposite charges bond with one another. In ionic compounds, metal elements are willing to donate an electron while nonmetals are willing to take it.

An ionic bond is produced between metallic and non-metallic atoms, where electrons are completely transferred from one atom to another. During this process, one atom loses electrons and another one gains them, forming ions. Usually, the metal gives up its electrons forming a cation to the nonmetal element, which forms an anion.

In other words, ionic bonding is based on the transfer of electrons, thereby forming electrically charged atoms, called ions. The positive ions are called cations, and the negative ions are called anions. Once the cations and anions are formed, electrostatic attractive forces build up between them, leading to bond formation.

That is, an ionic compound is made up of positive and negative ions, united by electrostatic forces of attraction.

So, molecules cannot form ionic bonds from the same atom because ionic bonds form when atoms with opposite charges bond with one another. In ionic compounds, metal elements are willing to donate an electron while nonmetals are willing to take it.

the correct answer is - d. china has a large and growing population.

the fact that china has a large (the biggest) population, and it is still growing, doesn't hinder the agriculture production in the country. in fact, it can for increased production in the agriculture, since there's more labor force, as well the sheer mass of people produces lots of scientists that come up with new inventions as to how to improve this sector. nice example is the inner mongolia region in china, in general dominated by the gobi desert, but few scientist came up with a nice idea as to how to make the region productive by using plants that are very resistant to droughts, so lots of people have been employed, and the region is becoming greener and greener each year, and the production of food in this region is also increasing.
