What does a mean on a 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.
What is the electrons in the outer most energy level of an atom called?
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 :)
How many elements are in the compound Mg?
Mg which stands for Magnesium is the element to begin with, not a compound.
Does atomic radius decrease and metalic character increase from left to right on the periodic table?
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.
What element on the periodic table begins with the letter j?
none look at a periodic table The element 'J' seems to crop up in a number of older books and journals. From my research it is the old name for Iodine

What elements begin with v?
Vanadium is a chemical element. It has the symbol V in the Periodic Table.
How did chemists begin the process of organizing elements?
chemists used the properties of elements to sort them in groups.
What are the empty spaces in the periodic table meant for?
It was recognized by the inventor of the Periodic table that these empty spaces are for elements/isotopes that would be discovered someday. Dmitri Mendeleev is generally credited with the publication, in 1869, of the first widely recognized periodic table. He developed his table to illustrate periodic trends in the properties of the then-known elements. Mendeleev also predicted some properties of then-unknown elements that would be expected to fill gaps in this table.

How did errors in the Mendeleev periodic table begin to show up?
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
Where the elements in period 3 of the periodic table are considered from left to right the degree of nonmetalic character of each successive element tends to do what?
The nonmetallic character begin with silicon and increase to right.
