D - block contains most elements....
ie,from 3rd group to 12th group
The transition metals are the most common, and are found in the middle (groups 3-12) of the periodic table.
Most organic compounds contain carbon and hydrogen. They may also contain oxygen, nitrogen, sulfur, or other elements in smaller quantities.
Most commonly, oxyacids contain 3 elements. They must contain Oxygen, Hydrogen, and a central atom that can be a variety of different elements. Here are some examples: HClO HBrO4- HIO
Most elements contain a mixture of isotopes, which are atoms of the same element with different numbers of neutrons. Isotopes can have different properties but behave similarly in chemical reactions due to their identical number of protons.
Oranges contain a variety of chemical elements, with the most abundant being carbon, hydrogen, and oxygen. They also contain smaller amounts of minerals such as potassium, calcium, and magnesium. Additionally, oranges contain trace amounts of elements such as iron, zinc, and copper.

That depends on the monomerCarbohydrates have the elements Carbon, hydrogen, and oxygenAmino acids have the elements carbon, hydrogen, oxygen, and nitrogenNucleotides have the elements carbon, hydrogen, oxygen, nitrogen, and phosphorus.Lipid is a broad category that may contain some or all of the elements listed above.
solids
Most organic compounds contain carbon and hydrogen. They may also contain oxygen, nitrogen, sulfur, or other elements in smaller quantities.
The elements that hydrocarbons contain are: -Hydrogen -Carbons
To determine which category contains the least elements, one would need to compare the number of elements in each category directly. Without specific categories or data provided, it is impossible to identify the category with the least elements. If you provide more context or the categories in question, I can offer a more precise answer.
