Answer:
Option B. Sodium and potassium lose electrons and chlorine gains them
Explanation:
Sodium and Potassium are both group 1 element. They both react with chlorine by losing 1 electron each and the chlorine atom accept the electron.
Sodium chloride(NaCl) can be formed by the equation below:
Na —> Na+ + e-
Cl + e- —> Cl-
Combining both equation together we obtained the following:
Na + Cl + e- —> Na+ + Cl- + e-
Eliminating the e-, we have:
Na + Cl —> Na+Cl-
From the above illustration, we can see that sodium loses electron and chlorine accepts/gain the electron
This is also applicable to potassium chloride as shown below:
K —> K+ + e-
Cl + e- —> Cl-
Combining both equation together we obtained the following:
K + Cl + e- —> K+ + Cl- + e-
Eliminating the e-, we have:
K + Cl —> K+Cl-
we can see also that potassium loses electron and chlorine accepts/gain the electron
Therefore, the correct answer to the question is option B
