In which set do all elements tend to form anions in binary ionic compounds? li, na, k n, o, i c, s, pb k, fe, br?

Atoms or molecule after gaining of electron possesses negative charge and is known as anion.

For the given sets:

The given elements are alkali metals and have tendency to lose electrons easily and form cations.

The given elements are non-metals and are electronegative. So, they gain electrons easily and form anion.

Carbon has tendency to form bond by sharing of electrons, Sulfur has tendency to gain electrons and form anion whereas Lead has tendency to lose electron.

Potassium and Iron has tendency to lose electron and form cation whereas Bromine has tendency to gain electron to form anion.

Hence, from the given sets, all elements of set: have tendency to form anions in binary ionic compounds.

you gotta add the following molecules so we can give u an answer

explanation:

a). in this case, dh> 0 and sd> 0. if t becomes larger, the term "-tds" will become more negative. at some point, it is possible that -dts will be more negative than the dh is positive, and the reaction will become spontaneous. this is probably the correct answer, but you should look at all of the other possibilities and make sure of that.
