Radium is a member of the alkaline earth family. in addition to being a part of this family, what is another property of radium that you can deduce from the information given in the periodic table? a) the atomic number tells us that radium is a synthetic element. b) based on its location overall, radium is considered a nonmetal. c) the atomic mass and atomic number tell us that radium is a radioactive element. d) the period number tells us that radium is the least reactive member of the family.

I'm not sure, but I'm pretty confident that the answer is C). The atomic mass and atomic number tell us that radium is a radioactive element.

Its C. I did this on usatestprep. Plz mark me brainliest and thank you

Explanation:

smooth muscle is composed of involuntary muscles found within the walls of organs and structures such as the esophagus, stomach, intestines, and blood vessels. those muscles push materials like food or blood through organs. unlike skeletal muscle, smooth muscle can never be under your control.

the best answer is d because the strong cohesion is caused by the ability of water molecules to undergo hydrogen bonding.

a is incorrect because when water solidifies, it becomes   ice, which expands and occupies a bigger volume for the same mass of water in its liquid state.

b is incorrect because water has high surface tension. besides bonding to itself it hydrogen bonds to other molecules at the top decreasing possibility for breaking of attractive forces.

c is incorrect because the water molecule has oxygen which is highly electronegative and so pulls the electron pair towards itself creating a dipole moment, making the molecule polar.

e is incorrect because water has strong adhesion, ability to stick to other molecules such as glass because of this molecules having stronger hydrogen bonding than water.
