Looking at the line plots on your graph, describe how boiling point and melting point vary with respect to atomic number. The boiling and melting points increase consistently as atomic number increases.

The boiling and melting points decrease consistently as atomic number increases.

The boiling and melting points go up and down as the atomic number increases and there is no clear trend.

Atomic line sis number acresss

Explanation:

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.
