K is the abbreviation for calcium.
A True
B False<\/p>\n\n\n\n

The Correct Answer and Explanation is :<\/strong><\/mark><\/p>\n\n\n\n

The correct answer is B. False<\/strong>.<\/p>\n\n\n\n

The abbreviation for calcium<\/strong> is not K<\/strong>. Instead, Ca<\/strong> is the chemical symbol for calcium, which comes from the Latin word calx<\/em>, meaning “lime.” The periodic table of elements assigns symbols to each element, and these symbols are typically one or two letters long. For example, K<\/strong> is the symbol for potassium<\/strong>, not calcium.<\/p>\n\n\n\n

Here\u2019s why:<\/p>\n\n\n\n

    \n
  1. Periodic Table Symbols<\/strong>: The periodic table assigns unique symbols to chemical elements, typically derived from their English or Latin names. Calcium, which has the atomic number 20, is symbolized as Ca<\/strong>, following the general pattern of using the first letter of the element’s name, with a second letter to distinguish it from other elements.<\/li>\n\n\n\n
  2. K for Potassium<\/strong>: The symbol K<\/strong> is used for potassium<\/strong>. This might be confusing because the letter K<\/strong> is not the first letter of “potassium.” However, K<\/strong> comes from the element’s Latin name kalium<\/em>, which has roots in Arabic, and was historically used to refer to potash, from which potassium was first extracted.<\/li>\n\n\n\n
  3. Naming Conventions<\/strong>: The use of K<\/strong> for potassium and Ca<\/strong> for calcium follows the pattern of assigning symbols based on historical, linguistic, or geographical reasons. This can sometimes lead to non-intuitive choices, such as Fe<\/strong> for iron (from ferrum<\/em>, its Latin name) or Na<\/strong> for sodium (from natron<\/em>, its Latin name for soda).<\/li>\n<\/ol>\n\n\n\n

    In summary, Ca<\/strong> is the correct abbreviation for calcium, and K<\/strong> is reserved for potassium. The naming conventions for elements often reflect their Latin roots or historical context rather than their English names, which is why potassium is represented by K<\/strong>, even though the first letter of “potassium” is not K<\/strong>.<\/p>\n","protected":false},"excerpt":{"rendered":"
