Question

Matter is composed of exceedingly small particles called atoms. An atom is the smallest unit of an element that can participate in a _______. A macroscopic sample of an element contains an incredibly large number of atoms, all of which have identical _______. Atoms of one element differ in properties from atoms of all other elements. A compound consists of atoms of two or more elements combined in a _______. Atoms are neither _______ during a chemical change; they're instead rearranged to yield substances that are different from those present before the change.

Answer 1

Answer: 1) chemical change 2) chemical properties 3) ratio? 4) created nor destroyed

Explanation: 1) Matter is composed of exceedingly small particles called atoms. An atom is the smallest unit of an element that can participate in a chemical change. 2) A macroscopic sample of an element contains an incredibly large number of atoms, all of which have identical chemical properties. 3) A compound consists of atoms of two or more elements combined in a small, whole-number ratio. In a given compound, the numbers of atoms of each of its elements are always present in the same ratio. 4) Atoms are neither created nor destroyed during a chemical change, but are instead rearranged to yield substances that are different from those present before the change
