Chapter 2 - Bonds Flashcards
Atomic Mass
Number of protons and neutrons in the nucleus
Atomic Number
Number of protons in the nucleus
Biological Half-Life
Time it takes for 50% of radioactive material to clear out of the human body
Electron
Subatomic Particle with -1 charge
Isotope
Element with different number of neutrons
Neutron
Subatomic particle with 0 charge
Physical Half Life
Time it takes for 50% of radioactive material to decay
Proton
Subatomic particle with +1 charge
Radioisotope
Element with unstable number of neutrons
This force holds ionic bonds together
Electrostatic
Ion
Atom that has gained or lost an electron
Anion
A negatively charged ion
Cation
A positively charged ion
What will you get if you add up the charges in an ionic bond
zero
Crystallized forms of lots of the same ionic compounds
Salt or lattice structure
Covalent Bonds
Bonds that share electrons
Shows which type of atoms and how many are in a molecule
Molecular Formula
Shows the relationship of atoms in a molecule
Structural Formula
Valence Shell
The outermost shell you’ll find electrons in
Hydrogen bond
Intermolecular force between partial positive and partial negative charges
Hydrophobic Interactions/Van der Waals Forces
Nonpolar to nonpolar
Reactants
What goes into a chemical reaction
Metabolism
All chemical reactions in the body
Products
What comes out of a chemical reaction
Catalyst
Anything that speeds up a reaction
Activation Energy
Energy required for reaction to occur (usually breaks existing bonds)
