electronegativity increases with the exception of the noble gases
Explanation:
in general, electronegativity decreases as you move down a group in the periodic table, this correlates neatly with the increase in distance between the atom’s nucleus and the electron valence.
Extrusive, or volcanic, igneous rock is produced when magma exits and cools above (or very near) the Earth's surface. These are the rocks that form at erupting volcanoes and oozing fissures.
