Question

26 kg : 39 kg :: ₹
200 ratio ₹ 300 true or false​

Answer 1

Step-by-step explanation:

Answer 2

Answer:

Alpha particles have +2 charge (positively charged particle) and 4 units of mass which means mass of 2 protons and 2 neutrons inside the nucleus.

Case of a Helium atom:

In a helium atom, there are 2 protons and 2 neutrons inside the nucleus.

If we remove two electrons from the atom, it will positively charged (+2) and this is similar to alpha particle..

And an alpha particle has no electrons to balance the positive charge of the two protons.

Hence:

Alpha particles are positively charged helium atoms (Option D).
