Trends On a Periodic Table

• Elements close to each other on the periodic table display similar characteristics.
• There are 7 important periodic trends
• Reactivity- metals and non metals show different trends
• The most reactive metal is Francium and the most reactive non-metal metal is Flourine.
• Ion charge- elements ion charges depends on their group melting point.
• elements in the center have the highest melting point.
• noble gases have the lowest melting point
• melting point increases from left to right until the middle of the table
• Atomic radius
• decreases to the up and the right
• helium has the smallest atomic radius
• Ionization energy- energy needed to completely move an electron from an atom
• increases going up and to the right
• all noble gases have high ionization energy
• helium is highest
• francium is lowest
• Electronegativity
• refers to how much atoms want to gain electrons
