Which of the following is true about metallic character, when we move from left to right in a period and top to bottom in a group?

The main group elements complete their elctron configuration using s and p electrons in the periodic table. These elements range from the most metallic to the most non-metallic , with intermiediate properties of semi-metals, in between . The elements which occur at the two extremes of the periodic table are highly reactive and therefore , these highly reactive elements do not occur in free state, they usually occur in the combined forms. Which of the following properties show opposite trend on moving along a period from left to right and from top to bottom in a group ?
