The group 1 elements are all soft, reactive metals with low melting points. They react with water to produce an alkaline metal hydroxide solution and hydrogen. |
Because Group 1 elements have wide atomic radii between neighbouring atoms, the melting and boiling points are lower than other metals. The atomic radius ... |
This is because francium is below caesium in the periodic table, so it should have a lower melting point, and the difference in melting point decreases going ... |
Less energy is required for boiling to happen. The boiling will occur at a lower temperature. Hence, the boiling point of Group-1 elements decreases down the ... |
