When the surface of a piece of chalk is scrapped the tiny particles that flake off are knwn as?
When the surface of a piece of chalk is scrapped the tiny particles that flake off are known as. A. Matter B. Molecules C. Elements D. Atoms…….. The flakes are particles of whatever the chalk is made of (calcium sulphate or carbonate plus a binding agent)…I needn’t remind you that atoms and molecules are not visible to the naked eyes...If the chalk is white, the flakes falling off are also white. Again atoms have no colors. Although molecules have characteristic colors, they can’t be seen with unaided eyes.. Now let’s assume the chalk is made up of a single compound let’s say Calcium sulphate (made up of Calcium, Sulphur and Oxygen elements)..individually and independently the smallest bit of a compound capable of independent existence is a molecule, the molecules in turn are made up of atoms of elements CHEMICALLY BOND TOGETHER. One cannot separate the atoms just by scrapping the chalk as they are again Chemically bonded. Notice how I used the word ATOMS for ELEMENTS and MOLECULES for COMPOUND. Meaning an ATOM is the smallest unit of matter that retains all the chemical properties of an ELEMENT and Molecule the smallest unit of a compound capable of independent existence, retaining all properties of that compound or Simply a group of atoms chemically bounded together…Again, the flakes settle on standing which suggests that they are actually PARTICLES, not ATOMS, not MOLECULES not ELEMENTS. PARTICLES is the most appropriate ANSWER to the above question..
