The correct option is D.

Transition metals are those metallic elements that are located in the central block of the periodic table. They exhibit various valency states and they generally have various colors. The atomic radius of an element refers to the measure of the size of its atom. For transition metals, their atomic radii decrease slightly and then start to increase, when one is moving from the left to the right of the periodic table.

Answer : The correct option is, Atomic radii decrease slightly and then start to increase.

Explanation :

Transition metals : It is defined as the element whose atom is ground state or ion in one of the common oxidation states, has incomplete d-subshell.

The general trend of atomic radii of transition metals is :

Generally the atomic radii of d-block elements in a series decreases with increase in atomic number but decreases in atomic size is small after midway that means almost remains same and at the end of the period there is a slight increase in the atomic radii.

Hence, the atomic radii decrease slightly and then start to increase of the transition metals when moving from left to right on the periodic table.

What change was caused by a change in temperature?

Lostsunrise [7]

Answer:

The temperature of the earth determines how much water there is in our atmosphere. Carbon dioxide is the most commonly discussed of the greenhouse gases. This has occurred primarily because of the huge amounts of carbon dioxide humans are moving from the earth to the atmosphere in the burning of fossil fuels.Explanation:

How will the vapor pressure of an aqueous solution of sodium chloride compare to that of pure water?

solmaris [256]

The vapor pressure of a compound refers to the pressure generated by the vapour of a compound in equilibrium with its condensed stage. The major determinant of a compound vapour pressure is temperature. The vapour pressure of an aqueous solution of sodium chloride will be lower than that of pure water. This is because, dissolution of solute in a solvent always reduces the vapour pressure of the solution as a result of interactions between the molecule of the solute and the solvent. Thus, a pure compound will always have a higher vapour pressure than a solution.

Function of leaf in points

klasskru [66]

Explanation:

The main function of a leaf is to produce food for the plant by photosynthesis. Chlorophyll, the substance that gives plants their characteristic green colour, absorbs light energy.

Photosynthesis.

Transpiration.

Guttation.
Storage.

Defense.

I will be describing what each of these do to the plant.

Photosynthesis: Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that can later be released to fuel the organisms' activities.
Transpiration: Transpiration is the process of water movement through a plant and its evaporation from aerial parts, such as leaves, stems and flowers. Water is necessary for plants but only a small amount of water taken up by the roots is used for growth and metabolism. The remaining 97–99.5% is lost by transpiration and guttation.
Guttation: Guttation is the exudation of drops of xylem sap on the tips or edges of leaves of some vascular plants, such as grasses, and a number of fungi. Guttation is not to be confused with dew, which condenses from the atmosphere onto the plant surface. Guttation generally happens during the night time.
Storage: A storage organ is a part of a plant specifically modified for storage of energy (generally in the form of carbohydrates) or water. Storage organs often grow underground, where they are better protected from attack by herbivores.
Defense: The first line of defense in plants is an intact and impenetrable barrier composed of bark and a waxy cuticle. Both protect plants against herbivores. Other adaptations against herbivores include hard shells, thorns (modified branches), and spines (modified leaves).

Hope this helps!
