In an ionic compound, the attraction between actions and _________ hold the compound together
Nady [450]
Answer: 
            The correct option in blank is anion.

Explanation:
                  Ionic compound is formed by the transfer of electron from one atom to another atom. When an electropositve atom lose an electron it form cation, whereas as anion is formed when an atom gain an electron. These actions and anions then attract each other and form an ionic compound.
I hope it will help you.

Example:
              The formation of NaCl is best example of ionic compound. Na has one electron in its outer most shell which can easily be removed to form Na+, while Cl has seven electron in its outer most shell so it can easily gain an electron lost by Na to form Cl-. Then these ions attract each other and form NaCl as shown in the figure.

Leya [2.2K]

Answer:

The correct answer is "I, II, and III".

Explanation:

The missing options of this question are:

I only

II only

III only

I, II, and III

The correct answer is "I, II, and III".

Antibiotics are of different spectrums of activity depending on the number of pathogens they can kill. They are different reasons for this differences in antibiotic specificity:

I. Antibiotics interrupt processes found in some but not all pathogen cells. For instance, some antibiotics are directed to cell walls that not all bacteria posses.

II. Some pathogens have no metabolic processes to interrupt. The antibiotics that are directed to metabolic reactions of bacteria are not effective in treating viruses because they do not perform this metabolic reactions.

III. Some pathogens have developed genetic resistance to specific antibiotics. Bacteria have a remarkable genetic plasticity having plasmids that can be easily transmitted among them, which give them antibiotic resistance.
