Which diagram is the correct electron dot diagram for magnesium?

Magnesium is in Group 2 (sometimes called Group II or 2A). Since it is in Group 2 it will have 2 valence electrons. When you draw the Lewis structure for Magnesium you'll put two "dots" or valance electrons around the element symbol (Mg).

fire could start, buildings collapsing, and ash falling from the sky.

explanation:

this is because the buildings or plants could catch on fire and the buildings would most likely collapse. lastly ash would fall because all the burning would cause ash to fall from the sky.

hope this .

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.
