What does energy star meani really don't know

ENERGY STAR is a symbol that certifies energy efficiency.

The US government certifies that products with this symbol use less energy than standard products.

For example, televisions with the ENERGY STAR symbol use on average 27 % less energy than uncertified models.

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.
