Question

Adding an alpha particle to nucleus of sodium atom, product will be

• A. ${Na}^{+}$
• B. ${Mg}^{2+}$
• C. ${Al}^{2+}$
• D. $Al$

Answer 1

The correct option is D

$\mathrm{Al}$

An $\mathrm{\alpha }$-particle is simply the nucleus of a doubly charged Helium atom.

The chemical reaction involved if alpha particle is added to the nucleus of Sodium ($\mathrm{Na}$) atom is:

${}_2{}^4\mathrm{He}+{}_{11}{}^{23}\mathrm{Na}\to {}_{13}{}^{27}\mathrm{X}$

The atomic number of product is 13.

So, the element present in the product is Aluminium ($\mathrm{Al}$).

Final answer:

Hence, option (D) is correct.
