Barium - Periodic Table of Elements and Chemistry

Characteristics: Barium is a metallic element chemically reseling calcium but more reactive. It is a soft, silvery metal and when cut it quickly turns a black color due to the formation of barium oxide, (BaO). It is also highly reactive with water or alcohol.

Explain why magnesium has a higher melting point …

Magnesium has 2 outer electrons compared to Sodium''s 1. Therefore it releases more electrons into the sea of delocalised electrons and it''s nucleus has a greater positive charge of +2 compared to Sodium''s +1. This means that Magnesium''s nucleus has a greater attraction on the delocalised electrons.
