The 14 elements following actinium on the Periodic Table are called the actinides. These elements all have similar chemical properties and are part of the f-block of the periodic table.
On the periodic table, "a" might be the first letter in the element aluminum or argon or arsenic. The letter "a" is not found alone in the periodic table but can be found in several elements that either begin with the letter or include the letter.
Metal elements that begin with the letter C include copper (metal), cesium (metal), and cadmium (metal). Carbon is a nonmetal, while cesium and cadmium are metals. There are no metalloids that begin with the letter C.
valence electrons.. every element wants to have 8 which is why there are ions and such.. elements which already have 8 to begin with are called noble gases and can be found on the last column on the periodic table :)
Mg which stands for Magnesium is the element to begin with, not a compound.
Metallic character decreases as you go across any single period of the Periodic Table. This is because metals are characterized by their ability to lose electrons to form cations; the easier it is to do so, the more reactive a metal is. Non-metals are characterized by their ability to gain electrons to form anions; the easier to do so, the more reactive a non-metal is. As you go across any single period, elements gain an extra valency electron. This makes it harder and harder for those elements to lose their valency electrons, thus becoming more and more non-metallic.

No element in the periodic table begins with the letter J.
Vanadium is a chemical element. It has the symbol V in the Periodic Table.
Chemists began organizing elements by noticing patterns in their properties. Dmitri Mendeleev created the first periodic table in the 1860s by arranging elements in order of increasing atomic weight and grouping elements with similar properties together. This laid the foundation for the modern periodic table.
The empty spaces in the periodic table are reserved for elements that have not yet been discovered or synthesized. These gaps allow for predictions of the properties of these yet-to-be-discovered elements based on their positions in the table and their relationships to neighboring elements.
On the periodic table, "a" might be the first letter in the element aluminum or argon or arsenic. The letter "a" is not found alone in the periodic table but can be found in several elements that either begin with the letter or include the letter.
When it was discovered that Mendeleev's table was based on the wrong characteristic. He believed that it was the mass of the elements that affected their properties. It is, in fact, their atomic numbers
The nonmetallic character begin with silicon and increase to right.
