The symbol and group number of the period 5 transition element whos atoms have the fewest protons

Y and group number 17

Explanation:

Iodine is the chemical element of symbol I and atomic number 53, belonging to group 17 or of the halogens, in the periodic table. It is an element that we can find both in its molecular form, and in a diatomic way. In addition, iodine is a trace element and is used in the field of medicine and photography, as well as in some cases it is used as a dye. In the field of chemistry, iodine is the least reactive halogen element. Like the rest of the halogens, iodine also forms diatomic molecules, in this case the diiodine (I2).

Iodine is part of numerous compounds, despite being the element with the lowest reactivity in its group. It has some characteristics of metals, and their oxidation states are -1, + 1, + 3, + 5, + 7.

Despite its use, it is the halogen as a minor abundance, with only 0.14 ppm concentration in the earth's crust, however, in seawater its abundance is exactly 0.052 ppm.

water   molecules stay close to each other through cohesion, the collective action of hydrogen bonds between water molecules. cohesion plants draw water upwards from the root through the stem's transport tubes (xylem) to the leaf. this transport occurs even in large trees and against gravity. transpiration, evaporation of water from plant leaves, creates a tension on water molecules being pulled up from the stem and roots.

water also has high (the attraction of one substance to another) properties because of its polar nature. adhesion of water molecules to plant cell walls counteract gravity while water is transported from roots to leaves.

water exhibits a very high surface tension when compared to other liquids. surface tension is a property of a liquid that holds the surface together and allows it to resist an external force. by capillary action, the water forms concave menisci inside the pores. the high surface tension of water pulls the concavity outwards, generating enough force to lift water from the roots to the leaves of plants.

thus, cohesion, along with adhesion and surface tension creates a capillary action that keeps water molecules interacting and moving through the plants out to the leaf cells.

therefore, option d) is the correct answer.
