What is the trend for melting point on the periodic table?
The melting and boiling points of the Group 1 elements decrease on descending the group. This is due to a decrease in the forces of attraction between the atoms. On crossing a period in the Periodic Table the atomic size decreases. On descending a group the atomic size increases.
What is scandium used for?
Scandium is mainly used for research purposes. It has, however, great potential because it has almost as low a density as aluminium and a much higher melting point. An aluminium-scandium alloy has been used in Russian MIG fighter planes, high-end bicycle frames and baseball bats.
How is molybdenum used?
Most molybdenum is used to make alloys. It is used in steel alloys to increase strength, hardness, electrical conductivity and resistance to corrosion and wear. These ‘moly steel’ alloys are used in parts of engines. Other alloys are used in heating elements, drills and saw blades.
What trends are in the periodic table?
Major periodic trends include: electronegativity, ionization energy, electron affinity, atomic radius, melting point, and metallic character. Periodic trends, arising from the arrangement of the periodic table, provide chemists with an invaluable tool to quickly predict an element’s properties.
What element has the highest boiling point?

How does scandium react with water?
When scandium particles react with water, they undergo oxidation and form scandium(III) hydroxide. Scandium loses all three of its valence electrons and gets a three plus charge state and bonds with hydroxide ions in water. The remaining hydrogen atoms combine and form hydrogen gas.
How many liquid elements are there on the periodic table?
There are eight liquid elements, if you include recently-discovered synthetic elements. Key Takeaways: Liquid Elements Only two elements on the periodic table are elements at room temperature. They are mercury (a metal) and bromine (a halogen).
Is there a printable periodic table of the elements in Spanish?
This Spanish color printable periodic table of the elements includes the element name, atomic number, symbol, and atomic weight. The colors denote the element groups. You can save the pdf version of this printable periodic table to your hard drive or can print it.
Is there a paper version of the periodic table?
Sometimes it’s nice to have a paper version of the periodic table of the elements that you can refer to when working problems or doing experiments in the lab. This is a collection of periodic tables that you can print and use. Note: For 2019 values featuring all 118 elements, more free printable periodic tables are also available.
Which elements are liquid at room temperature?
The only liquid elements at standard temperature and pressure are bromine (Br) and mercury (Hg). Although, elements caesium (Cs), rubidium (Rb), Francium (Fr) and Gallium (Ga) become liquid at or just above room temperature. Point at or click an element in the periodic table for more information:
