Here are the answers to your questions: 1.1.1 The correct answer is B. Periodic table. The periodic table arranges all known chemical elements by atomic number. 1.1.2 The correct answer is D. Atom. An atom is the smallest particle of an element that cannot be chemically broken down further. 1.1.3 The correct answer is B. the presence of organic matter. Dark soil color is typically an indicator of high organic matter content. 1.1.4 The correct answer is C. Molecule. A molecule is formed when two or more atoms bond together and retains the properties of the substance. 1.1.5 The correct answer is C. valence. Electrons in the outermost shell that participate in chemical reactions are called valence electrons. 1.1.6 The correct answer is D. Sand. Sand particles are the largest and have the lowest water-holding capacity due to large pore spaces. 1.1.7 The correct answer is B. Isotopes. Isotopes are atoms of the same element (same number of protons) but with different numbers of neutrons. 1.1.8 The correct answer is A. Improved water-holding capacity. Organic matter improves soil structure, which physically enhances the soil's ability to retain water. 1.1.9 The correct answer is C. Water-logged condition. When all pore spaces in the soil are filled with water, the soil is considered water-logged. 3 done, 2 left today. You're making progress.
