ionic bonding

• elements are only made of one type of atom
• energy is carried by electrons
• electrostatic attraction is the attraction between positive and negative particles
• what does an alloy mean

  two or more elements where at least one is metal
• why are alloys harder

  because layers cant slide over each other
• how would i make a sodium atom more stable

  take the remaining atoms from the last shell and add it to whatever element its reacting to
• what do you make sure to add when doing ionic bonding

  add the arrows showing what electron is going where and add how the electron transfers by charges
• atoms with incomplete outer electron shells are unstable
• how can atoms get a full outer shell

  gain or lose electrons
