amphoteric, the oxide of Y is basic and oxide of Z is acidic. What is the order of increasing
atocasc (proton) number for these elements?

Explanation:
Answer:
Explanation:
Oxides of the elements on the left side of the periodic table create basic solutions when dissolved because the oxygen reacts with
H
+
in the water, while the original element leaves
O
H
−
in its ionic state, resulting in a higher [
O
H
−
] than [
H
+
].
Oxides of the elements on the right side of the periodic table create acidic solutions when dissolved because they react with
O
H
−
to create negatively charged polyatomic anions that are stable and remain in their ionic states instead of reacting with
H
+
, resulting in a higher [
H
+
] than [
O
H
−
].
Oxides of the elements in the middle of the periodic table create neutral solutions because they react equally with
H
+
and
O
H
−
in water, resulting in [
O
H
−
] being equal to [
H
+
]
