B. by the sharing of electrons
Answer choices A and C are incorrect because covalent bonds form as a result of electrons (protons are kind of irrelevant). Answer choice D is incorrect because it describes an ionic bond.

Answer: The given statement is true.
Explanation: Ionization energy is defined as the amount of energy required to remove an electron from the outermost shell of an isolated gaseous atom.
General equation of ionization energy is given by:

- If the outermost electron is loosely bound to the nucleus which means that the electron can be easily removed form an atom, it will require less amount of ionization energy.
- And if the outermost electron is tightly bound to the nucleus which means that the electron cannot be removed easily from an atom. And hence, it will require more ionization energy.
Hence, the given statement is true.
Answer:
The greenhouse effect:
The process in which gases in the atmosphere trap heat from the sun and warm the Earth. is the natural warming of the Earth’s atmosphere Solar radiation enters the atmosphere mainly as light and some of that radiation is absorbed by the Earth’s surface then changed to heat that is reradiated into the atmosphere where it is absorbed by greenhouse gases then reradiated back to Earth again
