Given the atomic notation of 19/9 X, identify element X.
a fluorine
b neon
C potassium
d nickel

Explanation:

The notation refers to some element X that has 9 protons and 19 protons and neutrons (so that means 19-9 = 10 neutrons). The element that has 9 protons is fluorine (symbol F on the periodic table)

This means would update to

in chemistry, adhesion and cohesion are attractive forces that exist between molecules. they hold the molecules together from each other. they are different in that adhesive force exists between molecules of different substance while cohesive force happens between molecules of same substance.

adhesion between water and glass causes water molecules at the edge of water and glass interface to climb up the wall in a narrow glass tube. this is called capillary action. cohesion is what gives glass its shape and causes water to form a droplet.
