Answer:
X₂O₃ , Y₂O
Explanation:
Valency of an element tells how well that element can form compounds with other atoms.
It sometimes, is also determined by the number of hydrogen atoms that it combines with.
Oxygen usually has a valency of 2, or oxidation state of -2.
That means oxygen will need 2 more electrons in it's outer shell to form a configuration of a noble gas(octet configuration).
The oxidation state of an atom in a molecule gives the number of valence electrons it has gained or lost.
Assuming both X and Y are less electronegative than oxygen, X has a valency of 3 and OS of +3.
While forming a neutral compound, we need no net charge on the compound. In X₂O₃,
total charge on X is 2 x (OS of X)= 2 x ( +3) = +6
total charge on O is 3 x (OS of O)= 3 x ( -2) = -6
Net charge is 0.
Similarly, in Y₂O
total charge on Y is 2 x (OS of Y)= 2 x ( +1) = +2
total charge on O is 1 x (OS of O)= 1 x ( -2) = -2
Net charge is 0.
Answer is: Rutherford demonstrate that <span>J.J Thompson's Plum Pudding model was not accurate.
</span><span>Rutherford theorized
that atoms have their charge concentrated in a very small nucleus.
</span>This was famous
Rutherford's Gold Foil Experiment: he bombarded thin foil of gold
with positive alpha particles (helium atom particles, consist of two protons and two neutrons).
Rutherford observed the
deflection of alpha particles on the photographic film and notice that most of alpha particles passed straight through foil.
That is different from Plum Pudding model<span>, because it shows that most of the atom is empty space.</span><span>
