Question

Alkali metals from ionic compounds with the halogens give reason

Answer 1

Answer:

alkali meatals have only one electron in the outermost shell and they tend to lose one electron..... Also halogens have 7 electrons in outermost shell and they need only one to complete the octet..... hence they accept OK ne electron from alkali metals and for ionice compounds

Answer 2

Explanation:

alkali metals tend to loss one electron and form ions with a single positive charge. They form ionic compounds (salt) in reaction with the halogens (alkali halides) sodium and potassium ions form important constituent of body fluids (electrolytes).
