How is metallic character shown on the periodic table?
The metallic elements on a periodic table may be represented by a certain color unlike those of other elements. Most periodic tables have elements in different colors, so try looking at the key that shows what each color represents for that element.
When looking at a periodic table of elements what do you know by knowing in which column an element appears?
Chemical elements in the same group have similar chemical properties.
How do you find the atomic number of an element?
Look it up in "periodic table of elements" You can find the number of a particular element by looking at the Periodic Table; you can also do this by counting the number of protons in the nucleus.
What predicts an element's properties?
The answer you are probably looking for is the periodic table, which arranges the elements. The periodic table can help predict properties of an element based on the element's location. All the elements in a veritcle collum (also known as family or group) will have the same number of valence electrons and thus behave in a similar manner. Elements can also be compared to one another on the horizontal axis(the period). i.e. moving from left to right elements become less metalic and do not exibit metallic properties as stongly. General location on the table can tell you what type of element it is; metal, nonmetal, metalloid/semimetal. or the # of protons and electrons in the element, the atomic mass.
What are the elements in the second period of the periodic table of elements?
You can discover this by looking at a periodic table of the elements.The rows of the table are called periods; the columns are called groups.The second period therefore begins with the element Lithium and ends with the element Neon.
What elements can have variable oxidation numbers are known as known as what group of elements?
Most elements can have more than one oxidation number, but I think you are looking for the transition elements in groups 3 - 12.
How can you show that carbon is not a metal?
By looking at the periodic table of the elements. Carbon is listed as a nonmetal.
Is a gum Arabic a element?
No, if whatever you are looking for does not appear on the Periodic Table of Elements then it is not an element.

When looking at a periodic table of elements what do you know by knowing in which column an element appears?
Chemical elements in the same group have similar chemical properties.
How many elememnts are in the periodic table?
There are either 118 or 117 elements in the peiodic table. it depends on the one that you are looking at.
How do you determine the electrical charge of an atom?
I believe you use a periodic table to find the specific element you're looking for.
If you were looking for a very reactive atom would you look in group 1 or 18?
The most reactive chemical elements are in the first group of the periodic table of elements.
How are elements found on the periodic table?
It depends on the Periodic Table you're looking at. There are currently 117 confirmed elements; of those, 111 have been named by the IUPAC (International Union of Pure and Applied Chemistry), not including systematic names.
What elements on the Periodic Table make salt?
The answer is Group 17 Halogens.
How many elements are found on the Periodic Table?

How can you determine the number of energy rings an atom has by looking at the periodic table?
The number of energy levels is equal to the period number of the element. Through a group, the number of energy levels increases. All the elements in a period has the same number of energy levels.
