Close
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
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.
Bonding Ionic STRUCTURE- Ionic Lattic
properties of ionically bonded structures-high melting point, soluble in water, conducts electricity when in solutions or molted .
