The atomic mass of beryllium (be) is 9.01 amu. the atomic mass of calcium (ca), which is in the same group as beryllium, is 40.08 amu. based only on this information, what would you predict to be the atomic mass of magnesium (mg), which is also in the same group but is between be and ca?

It would have a value between 9.01 amu and 40.08 amu.

Explanation:

Hello,

In this case, considering that magnesium is located between beryllium and calcium, its atomic mass will be between 9.01 amu amdn 40.08 amu based on the nowadays organization of the periodic table based on the atomic sizes as well. In such a way, magnesium's atomic mass is about 24.305 amu. This fact is substantiated via the periodic trends associated with the molar mass which states that the higher the period (the atomic radius as well), the higher the molar mass.

Best regards.

both adhesion and cohesion are attractions.

they are different in that adhesion is the force of attraction between the molecules of two different substances, whereas cohesion is the force of attraction between molecules of the same substance.

possible examples include capillary action, in which the adhesion between water and glass causes the water to rise in a narrow tube against the force of gravity.

because of hydrogen bonding, water is extremely cohesive.

this causes molecules on the surface of water to be drawn inward, which is why drops of water form beads on smooth surfaces.

hope this .
