In the late 1800s, Mendeleev developed a periodic table of the elements based largely on atomic mass. In the early 190 the periodic table based on increasing atomic number. Which evidence supported Mosely's modification to Mendeleev's

the answer is alpha particles hope i you

the atomic number will stay the same no matter how many electrons it has, so it doesn’t decrease nor increase. it’ll only change with a different number of protons

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.
