What particle is needed to complete this nuclear reaction 222 86 rn }218 84 po?

To complete this reaction a helium particle must be added.

²²²Rn₈₆ --> ²¹⁸Po₈₄ + ⁴He₂

This reaction is an example of α decay. In this decay an unstable atom becomes stable by emitting αparticle that is a nuclei a helium so its mass is reduced by 4 units and its atomic number is reduced by 2 units. And the atom becomes stable .

On going from ²²²Rn₈₆ to ²¹⁸Po₈₄, we can see that there is difference in mass number of 4 and in atomic number of 2. So this is clear that a helium nuclei is emitted.

to be fair, you have to have a very high iq to understand rick and morty. the humour is extremely subtle, and without a solid grasp of theoretical physics most of the jokes will go over a typical viewer's head. there's also rick's nihilistic outlook, which is deftly woven into his characterisation- his personal philosophy draws heavily from narodnaya volya literature, for instance. the fans understand this stuff; they have the intellectual capacity to truly appreciate the depths of these jokes, to realise that they're not just funny- they say something deep about life. as a consequence people who dislike rick & morty truly are idiots- of course they wouldn't appreciate, for instance, the humour in rick's existential catchphrase "wubba lubba dub dub," which itself is a cryptic reference to turgenev's russian epic fathers and sons. i'm smirking right now just imagining one of those addlepated simpletons scratching their heads in confusion as dan harmon's genius wit unfolds itself on their television screens. what fools.. how i pity them.

and yes, by the way, i do have a rick & morty tattoo. and no, you cannot see it. it's for the ladies' eyes only- and even then they have to demonstrate that they're within 5 iq points of my own (preferably lower) beforehand. nothin personnel kid

it is to be noted that an alpha particle is an helium nucleus. so it contains 2 protons 2 neutrons and has a mass number of 4. when alpha decay particles are ejected from the nucleus it gets transformed into an atom which has atomic number less than 2 and a mass number less than 4.

an equation that could represent alpha decay is radium 226 decay of alpha particle forms radon 222.
