BIO 103 Chapter 2 Vocab Test Crossword

Down: 1) Negative ion that is formed by an atom gaining one or more electrons 2) Positively charged particle that resides in the atom's nucleus 3) Very weak interaction between molecules due to temporary charges attracting atoms that are very close together 5) Ability of some elements to attract electrons (often of hydrogen atoms), acquiring partial negative charges in molecules and creating partial positive charges on the hydrogen atoms 6) Positive ion that is formed by an atom losing one or more electrons 7) Molecules that share overall structure and bonding patterns, but differ in how the atoms are three dimensionally placed such that they are mirror images of each other 10) Ion necessary for nerve impulse conduction, muscle contractions, and water balance 11) Molecule that donates hydrogen ions and increases the concentration of hydrogen ions in a solution 12) Arrangment of electrons in an atom's electron shell 15) The amount of heat one gram of a substance must absorb or lose to change its temperature by one degree Celsius 17) Movement of electrons from one element to another; important in creating ionic bonds 18) Total number of protons in an atom 23) Process leading to rearranging atoms in molecules 25) Occurs because water molecules are attracted to charges on the inner surfaces of narrow tubular structures such as glass tubes, drawing the water molecules to the tubes' sides 26) Substances that resists a change in pH by absorbing or releasing hydrogen or hydroxide ions 28) Weak bond between slightly postively charged hydrogen atoms and slightly negatively charged atoms in other molecules 30) Intermolecular forces between water molecules caused by the polar nature of water; responsible for surface tension 31) One of 118 unique substances that cannot break down into smaller substances 34) Type of strong bond formed between two atoms of the same or different elements; forms when electrons are shared between atoms. Covalent bonds are the strongest and form the backbone of biological macromolecules 35) Steady state of relative reactant and product concentration in reversible chemical reactions in a closed system 36) Substance capable of dissolving another substance 39) Molecules that differ from one another even though they share the same chemical formula

Across: 2) Scale ranging from 0 to 14 that is inversely proportional to the hydrogen ions' concentration in a solution 4) Uncharged particle that resides in an atom's nucleus 8) Type of covalent bond that forms as a result of unequal electron sharing, resulting in creating slightly positive and negative charged molecule regions. 9) Chemical reaction that functions bidirectionally, where products may turn into reactants if their concentration is great enough 13) Negatively charged subatomic particle that resides outside of the nucleus in the electron orbital 14) Release of an ion from a molecule such that the original molecule now consists of an ion and the charged remains of the original, such as when water dissociates into H+ and OH-16) Outermost shell of an aotm 19) Isomer with similar bonding patterns differing in the placement of atoms alongside a double covalent bond 20) Molecules that share a chemical formula but differ in the placement of their chemical bonds 21) Tension at the surface of a body of liquid that prevents the molecules from separating; created by the attractive cohesive forces between the liquid's molecules 22) Total number of protons and neutrons in an atom 24) Hydrocarbon consisting of closed rings of carbon atoms 27) One or more forms of an element that have different numbers of neutrons 29) Molecule that takes part in a chemical reaction 32) Anything that has mass and occupies space 33) Core of an atom; contains protons and neutrons 37) Calculated mean of the atomic weights of an element's isotopes 38) Molecule that is a result of a chemical reaction 40) Chemical bond that forms between ions with opposite charges (cations and anions). Formed through the complete transfer of electrons, resulting in oppositely charged ions that attract each other. Ionic bonds create stable structures essential for various biological functions, such as nerve transmission 41) Describes uncharged nonpolar molecules that do not interact well with polar molecules such as water. Means "water-fearing", these substances are nonpolar and do not mix with water. Example: OIive oil 42) Attraction between water molecules and other molecules 43) Molecule that donates hydroxide ions or otherwise binds excess hydrogen ions and decreases the hydrogen ions' concentration in a solution 44) Rule that atoms are most stable when they hold 8 electrons in their outermost shells 45) Element with filled outer electron shell that is unreactive with other atoms 46) Molecule that consists only of carbon and hydrogen 47) Interaction between two or more of the same or different atoms that results in forming molecules
