- CContains more protons
- DIs a different element
✓
Answer
Correct option: A.
Contains more neutrons
a
(a) $_6{A^{12}}$ and $_6{X^{13}}$ both are isotopes but have different no. of neutrons.
(a) $_6{A^{12}}$ and $_6{X^{13}}$ both are isotopes but have different no. of neutrons.
$_6{A^{12}}$, For $A$ have $p = 6,e = 6$ and $n = 6$ and
$_6{X^{13}}$, For $B$ have $p = 6,e = 6$ and $n = 7$
