Which characteristics of metal atoms help explain why valence electrons in a metal are delocalized? Metal atoms are large and have high electronegativities.
Metal atoms are small and have low electronegativities.
Metal atoms are large and have low electronegativities.
Metal atoms are small and have high electronegativities.

The answer is c:  Metal atoms are large and have low electronegativities.

explanation:

right on Edu 2020

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.
