Document Summary
Law of conservation of matter matter may be transformed form one type of substance to others. Atoms, isotopes, and ions are chemical building blocks. Element- a fundamental type of matter, a chemical substance with a given set of properties that cannot be broken down into substances with the properties. Atoms- the smallest components of that maintain the chemical properties of that element. Nucleus- protons (positively charged particles) neutrons (particle with no charge) Isotopes- atoms of the same elements with differing numbers of neutrons. Half-life- the amount of time it takes for half of the atom to give off radiation. Ions- electrically charged atoms or combination of atoms. Molecules- combination of two or more atoms. Compound- a molecule composed of atoms of two or more different elements. Covalent bond- atoms in a molecule share electron. Solutions- elements, molecules coming together without chemically bonding. Ionic bonds- a transfer creates oppositely charged ions or reacting. Matter is composed of organic and inorganic compounds.
