Which element has an atomic mass of 65.38?

acid rain: rain that is polluted by acid in the atmosphere and damages the environment. acid: any material that can accept a pair of electrons and has a pH less than 7. agriculture: growing plants and raising animals for food and other products. alcohol: any organic compound in which a hydroxyl group (–OH) is bound to a saturated carbon atom. alkaline: having a pH greater than 7. allotropes: different structural forms of an element in which the atoms of the element are bonded together in a different way. alloy: a mixture of two or more metals, or of a metal and another element. alpha decay: when a nucleus breaks apart and emits a helium nucleus, called an alpha particle. amu: a unit of measurement, atomic mass unit, used to measure the mass of atoms and molecules. anion: an atom or group of atoms with a negative charge. anode: the electrode where oxidation occurs. aqueous solution: a solution in which the solvent is water. atmosphere: a unit of measure of pressure.

atom: the smallest particle of matter that cannot be broken down by chemical means. An atom is made up of a nucleus of protons and neutrons, surrounded by a cloud of electrons. atomic mass: the sum of the number of protons and neutrons in an atom’s nucleus. atomic number: the number of protons in an atom’s nucleus. atomic symbol: the symbol that represents an element on the periodic table. Avogadro’s law: a law that states that the molar volumes of all ideal gases are the same. base: a substance that accepts a hydrogen ion (H+) from another substance. Examples include baking soda, ammonia, and oven cleaner. basic: having a pH lower than 7. beta decay: a kind of radioactive decay of an atomic nucleus when an electron called a beta particle is emitted. biochemistry: the study of chemistry in living things. biology: the study of life and of living organisms. boiling point: the temperature at which a liquid boils. Boyle’s law: a gas law that states that the pressure and volume of a gas have an inverse relationship, when temperature is held constant.

carbon: an element found in all organic compounds. catalyst: a material that increases the rate of a chemical reaction without being consumed in the reaction. cathode: the electrode where reduction takes place. cation: an atom or group of atoms with a positive charge. cellular biology: the study of cell structure and function. characteristic: a feature of a person, place, or thing, such as blue eyes or curly hair. Charles’s law: a gas law that describes how gases expand when heated, and the relationship between volume and temperature. chemical equation: the use of symbols to represent a chemical reaction, with reactants on the left and products on the right. chemical reaction: a process where one or more substances are chemically charged and transformed into different substances. chemistry: the study of the properties of substances and how they react with one another. chromatography: a method of separating a mixture by passing it through a third material.
