The edge length of the unit cell is 524 pm.

Potassium

The chemical element potassium has the atomic number 19 and the letter K (which stands for kalium in Neo-Latin). Potassium is a silvery-white metal that may be easily and gently sliced with a knife. [6] Within seconds of exposure, potassium metal quickly combines with air oxygen to produce flaky, white potassium peroxide. It was initially separated from potash, which is made up of plant ashes and from which it gets its name. Potassium is an alkali metal in the periodic table. All alkali metals have a single valence electron in the outer electron shell, which can be removed easily to produce a positive-charged ion called a cation, which interacts with anions to form salts.

How does crop rotation help preserve soil?
vitfil [10]

Answer:Crop rotation also helps to battle against the forces of erosion. Rotating crops helps to improve soil stability by alternating between crops with deep roots and those with shallow roots. Pests are also deterred by eliminating their food source on a regular basis. Crop rotation is the practice of growing a series of dissimilar or different types of crops in the same area in sequenced seasons. It is done so that the soil of farms is not used for only one set of nutrients. It helps in reducing soil erosion and increases soil fertility and crop yield. The goal of crop rotation is to reduce the amount of the pest population present in the soil. Some pathogens that cause diseases survive in the soil from year to year in one form or the other, usually as sclerotia, spores, or hyphae. Rotating to non-host crops prevents the buildup of large populations of pathogens.
