Explanation:
While atomic radii DECREASE across a Period, a row of the Period Table, from left to right as we face the Table, atomic radii INCREASE down a Group, a column of the Periodic Table, due to the shielding of the valence electrons by the closed valence shell(s) that intervenes between the nucleus and the valence, outermost electrons.
Answer:
It is a Cline or layer where density gradient is greatest within a body of water
Iodine has 53 protons. For question 82, the number 127 stands for neutrons plus protons. So the neutron for I-127 is 74. For 83, according to the definition of isotopes, they need to have the same number of protons and different number of neutrons. I-127 and I-131 satisfy these requirements. For 85, the half life of I-131 is 8 days which means after 8 days, only half of sample remains unchanged. So if 80 gram change to 1.25 gram, it goes through 6 half life. So it took 48 days.
Answer:
movement of water from an area of lower solute concentration to an area of higher solute concentration
Explanation:
suppose two compartments separated by a semipermeable membrane, so that one contains water (compartment A) and the other a concentrated saline solution (compartment B). In this situation there is a greater chemical potential of the water present in A, which manifests itself as a diffusion tendency towards B, diluting this solution accordingly.
