Question

when sodium reacts with chlorine...
a sodium becomes a neutral atom.
b sodium accepts an electron from chlorine and becomes a positively charged ion.
c sodium donates an electron to chlorine and becomes a negatively charged ion.
d sodium donates an electron to chlorine and becomes a positively charged ion.
e sodium accepts an electron from chlorine and becomes a negatively charged ion.

Explanation:

Sodium has 1 valence - electron and chlorine has 7 valence - electrons. In the reaction, sodium donates its valence - electron to chlorine. When an atom donates an electron, it loses a negative charge and becomes a positively charged ion (cation).

Answer:

D. Sodium donates an electron to chlorine and becomes a positively charged ion.
