Answer:
Correct answer is a. Ag(s) reacts spontaneously with 1M H+(aq).
Explanation:
A charasteristic of metals is that they lose easily electrons, cations tends to gain electrons to react and anions tends to lose or share electrons to react.
If you want to make a chemical reaction you must to mix a reagent that tends to lose electrons with other that tends to gain them.
In the statement (a) we have a metal that loses electrons and a cation that can obtain them, so is the right answer.
note that the other optios have :
b) Metal with metal cation, not react beacause left a medium of reaction.
c) Both loses electrons
d) Both tends to gain electrons.
Answer:
VII'th group, negative ion
Explanation:
Usually fluorine is located in the seventh(VII) group as fluorine has 7 electrons in it's outer shell with chemical symbol "F"
Fluorine has 7 electrons in it's outer shell therefore, it needs one more electron to get the noble gas configuration. So more electrons means negative ion.
