Fill in the blanks :
$(1)$ In a galvanic cell,the anode and cathode possess $\dots$ and $\dots$ charge respectively.
$(2)$ According to convention,the anode and cathode in a galvanic cell are present on the $\dots$ and $\dots$ side respectively.

(N/A) $(1)$ In a galvanic cell,the anode is the negative electrode (site of oxidation) and the cathode is the positive electrode (site of reduction). Thus,the charges are negative and positive respectively.
$(2)$ By convention,in a standard cell diagram (cell notation),the anode is written on the left side and the cathode is written on the right side.
