What is the Law of Conservation of Mass? | The law of conservation of mass states that the mass cannot be created or destroyed in a chemical reaction. |
How is an ionic bond formed? | An ionic bond is formed when one or more valence electrons are transferred between atoms. An ionic bond is the force of attraction that holds cations and anions together. |
How is a covalent bond formed | a covalent bond is formed when pairs of valence electrons are shared among atoms. |
How is a metallic bond formed | a metallic bond is formed when metal atoms become cations and share a pool of freely moving valence electrons between their nuclei. |
why do atoms react to form chemical bonds | some atoms react to form chemical bonds to achieve a more sable electron configuration like those of a noble gas. |
what is a ion | an ion is an atom or groups of atoms that has gained or lost electrons and has a positive or negative charge. EX. Na+ or F- |
list the five general types of chemical reactions and write the general equation for each | synthesis: A+B->AB Decomposition: AB->A+B single-replacement: A+BC->B+AC Double-replacement: AB+CD->AD+CB Combustion: CxHy+O2->CO2+H2O |
