Question 37

The table describes two changes in neutral atoms of the same isotope.

Atom	Change
X	Absorbs radiation and moves an electron to a higher orbit within the atom
Y	Loses two outer electrons

Which compares the final relative charges and mass numbers?

[1]

X has charge $+ 1$ , Y has charge $+ 2$ ; Y has a lower mass number.

X has charge $0$ , Y has charge $+ 2$ ; Y has a lower mass number.

X has charge $0$ , Y has charge $+ 2$ ; their mass numbers are equal.

X has charge $+ 1$ , Y has charge $+ 2$ ; their mass numbers are equal.
