The outer energy level of electrons. What are valence electrons? Tells how many protons are in the nucleus and identifies the element. What is the atomic number? Negatively charged particles in the atom. What are electrons? Most reactive metals. What are the alkali metals in group 1? This type of reaction combines two or more elements to create a new substance. What is a synthesis reaction? When a positive ion is attracted to a negative ion. What is an ionic bond? When blue litmus paper turns red. What is an acid? Chemical equations must be balanced because of this law. What is conservation of matter? When energy is absorbed in the reactants. What is an endothermic reaction? Particles are locked in position and can only vibrate in place. What is a solid? When a solid changes directly in to a gas. What is sublimation? When a gas turns in to a liquid. What is condensation? The amount of space an object takes up. What is volume? Mass divided by volume. What is density? The subscript in a chemical formula tells this. What is the number of atoms of that element? This element is the backbone of all living organisms. What is carbon? This number multiplies the amount of a substance. What is a coefficient? The ability of a solute to be dissolved in a solvent. What is solubility? The lower the pH on the scale the more of “this” is present. What are hydrogen ions in an acid? An energy-rich organic compound made of the elements carbon, hydrogen and oxygen. What are carbohydrates? The body uses this from food to build and repair body parts and to regulate cell activities. What are proteins? Most fuels are made of these. What are hydrocarbons? These have the same number of protons but different number of neutrons. What are isotopes? Malleability, ductility and conductivity are due to the sea of electrons in this . What is a metallic bond?
