Question

α - particles are: (A) ionized helium atom (B) hydrogen atom (C) neutral atom (D) all of the above

Tardigrade Admin · Accepted Answer

α - particles or a-rays are a highly ionizing form of particle radiation which have low penetration. They consists of two protons and two neutrons bound together into a region identical to a helium nucleus, hence, it can be written as He2+

Q. $α -$ particles are:

ionized helium atom

hydrogen atom

neutral atom

all of the above

$α -$ particles or a-rays are a highly ionizing form of particle radiation which have low penetration. They consists of two protons and two neutrons bound together into a region identical to a helium nucleus, hence, it can be written as $H e^{2 +}$
