Starts with B A fast moving particle ejected when a neutron converts to an electron and proton. Starts with C element number 6 Starts with D Direction an excited electron falls Starts with E A subatomic particle with a negative charge. Starts with F A neutral atom with 9 electrons Starts with G The state of matter for elemental oxygen, fluorine, neon and hydrogen Starts with H The electrically neutral element with the least amount of electrons. Starts with I The halogen below bromine that is needed to produce thyroid hormones Starts with J We say electrons have to do this to get from one orbital to a higher orbital Starts with K The elemental symbol for potassium. Starts with L All elements heavier than this element are radioactive. Starts with M Group 3 through 12 make up the transition ____. Starts with N An atom with equal numbers of protons and electrons is said to be electrically _____. Starts with O This element has six valence electrons Starts with P An element used in light bulbs, fertilizers and explosives. Starts with Q The smallest unit of energy Starts with R An atom that releases ionizing radiation is said to be _____. Starts with S Element with six valence electrons that is used in matches, explosives and pesticides. Starts with T The synthetic element with the lowest atomic number. Starts with U Element used in nuclear bombs and reactors. Starts with V Name for electrons in the furthest orbital from the nucleus that participate in chemical interactions. Starts with W A liquid made from combining an oxygen atom with two hydrogen atoms Starts with X The element with 8 valence electrons that is in the 5th period. Starts with Y A transition metal in group 3 and period 5. Starts with Z When combined with copper and an electrolyte, electrons from this element flow to the copper and act as an anode.
