Which statement best describes how atoms combine to form sodium chloride (nacl)? a. a positively charged sodium ion and a positively charged chlorine ion form an covalent bond. b. a positively charged sodium ion and a negatively charged chlorine ion form an covalent bond. c. a positively charged sodium ion and a positively charged chlorine ion form an ionic bond. d. a positively charged sodium ion and a negatively charged chlorine ion form an ionic bond.

The answer is D. A positively charged sodium Ion and a negatively charged chlorine ion form an ionic bond.

Option (D) is the correct answer.

Explanation:

A bond generated after transfer of an electron from one atom to another is known as an ionic bond. And, a bond generated by sharing of electron(s) between two atoms is known as a covalent bond.

Sodium is a metal with atomic number 11 and electronic distribution 2, 8, 1. On the other hand, chlorine is a non-metal with atomic number 17 and electronic distribution 2, 8, 7.

So, in order to attain stability sodium will lose one electron and develop a positive charge as . Whereas chlorine at the same time will take up one electron from sodium atom and acquire a negative charge as .

Thus, we can conclude that the statement a positively charged sodium ion and a negatively charged chlorine ion form an ionic bond.

explanation:

since this is put under health, i would define "ethical (medical) behavior" the way the oath for doctors is recited.   "first do no harm."

but the term in general means when given a choice between right and wrong, we should always choose right. if we do, then we are practicing ethical behavior.

the movie was based there, and all the animals and characters are native.
