A change in matter that produces on or more new substances
Answer:
5. Atoms with high ionization energies and high electron affinities have low electronegativities.
Explanation:
Ionization energy is the minimum amount of energy which is required to knock out the loosely bound valence electron from the isolated gaseous atom.
Electron affinity is the amount of energy released when an isolated gaseous atom accepts electron to form the corresponding anion.
Electronegativity is the tendency of an atom in a bond pair to attract the shared pair of electron towards itself.
Low ionization energies as well as low electron affinities mean the atom has low effective nuclear charge, which results in the less attraction of the valence electrons by the atom and thus, low electronegativity.
Answer:
Yes
Explanation:
Because if you multiply it with waffles you get salad
Element Oxidized: S (S^(2-) --> S⁰)
Element Reduced: N (N^(5+) --> N(2+))
Oxidizing Agent: HNO3
Reducing Agent: H2S
THE ANSWER SHOULD BE THE PERIODIC TABLE I THINK
