What the the noble gas configuration for Boron

[He]23

Explanation:

The electron configuration for Boron is 123, but you can also write it as the noble gas configuration, which is [He]23

Note that helium has the configuration of 1, so we instead of writing it, we write [He]. This can be useful when writing the configurations of elements from the later periods as it saves space.

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.
