In a piece of silver where would you find the valence electrons

Silver has the atomic symbol Ag and only has 1 valence electron. You can base silver’s group number using the periodic table to look for its valence electrons or using electronic configurations. The number of electrons in the outermost shells equates to the number of valence electrons the element has. In this case, silver’s electronic configuration is 4d^10 5s^1, showing only one outer shell or valence electron. 

it forms an anion that has a larger radius. anions have a negative charge and are larger than the original atom.
