| Question | Answer |
| number of protons=atomic neutrons=mass-atomic electrons=number of protons solid that dissolves-solute liquid in which solute dissovles-solvent isotopes-atoms with same number of protons but different number of electrons average mass- relative atomic mass | chemistry Element-substance-one atom-not broken down. Atom- simplest particle of an element-own stable enviro. Compound-substance 2 or more elements chemically combined. electrons=neg nucleus and protons=positive neutrons=no charge |
| ions: its a charged particle formed when an atom gains or losses an electron. MOLECULAR ION- charged particle containing more than 1 atom. POSITIVE ION- cation NEGATIVE ION- anion simple ion formed when an atom loses or gains an electron to achieve full outer shell. overall charge of ion depends on number of positive protons and number of negative electrons. BONDING-its the way in which molecules and structures are held together. 3 types or ionic, covalent & metallic. | IONIC- occurs in compounds composed of metal or non-metal. COVALENT- occurs between Non-metal atoms -can be im compounds such as hydrogen chloride. METALLIC- occurs in metals |
| Bonding Ionic STRUCTURE- Ionic Lattic properties of ionically bonded structures-high melting point, soluble in water, conducts electricity when in solutions or molted . |
