MCQ
In helium nucleus, there are
- A$2$ protons and $2$ electrons
- B$2$ neutrons, $ 2$ protons and $2$ electrons
- ✓$2$ protons and $2$ neutrons
- D$2$ positrons and $2$ protons
✓
Answer
Correct option: C.
$2$ protons and $2$ neutrons
c
(c) Helium nucleus $→ _2H{e^4}$.
Number of protons $= Z = 2$
Number of Neutrons $= A -Z = 2.$
(c) Helium nucleus $→ _2H{e^4}$.
Number of protons $= Z = 2$
Number of Neutrons $= A -Z = 2.$
