A group is a vertical column on the Periodic Table. There are a total of 18 groups. They tell you how many electrons beyond an even eight that the elements have. For example, in group 1, each element has one more electron than an octet (9, 17, 25, etc).
However, be careful! The transition metals (columns 4 through 12) do not follow this rule. The rule picks up again at group 13. Therefore, group 1: 1 extra electron, group 2: 2 extra electrons, group 13: 3 extra electrons, group 14: 4 extra electrons, etc.
What else can I help you with?
How are the properties of elements shown by the periodic table?
The periodic table shows the atomic number, symbol, mass number, density of an element. Elements are arranged in periodic table such that their physical and chemical properties follows varies in a systematic way.
What does the color on an element block tell me?
Read the explanations under your periodic table; not all periodic tables have colors.
What direction do periods run and what do they tell us in a periodic table?
They run from left to right
How can you tell which elements of the periodic table are in the same period?
By number of elctrons,protons in them and their reaction rate
What information can you gather from the position of an element in the periodic table?
From the location on a periodic table, it is possible to tell how some elements will behave. Elements in one group usually have similar characteristics.
How do you tell electronegative levels on a periodic table?
Electronegativity increases while moving left to right along the period and decreases down the group in the periodic table.
What does periodic table tell you?
The periodic table tells you chemical elements. :)
How do you tell the p sublevel from the periodic table?
The p-block on the periodic table is the chunk of mostly nonmetals starting at group 13 that ends at the Noble gases on the far right side.
What does the periodic table tell you about the element in a group?
The periodic table tells you that elements in the same group have similar chemical properties because they have the same number of valence electrons. This influences how they react with other elements and helps predict their behavior in compounds.
What do the periods along the sides of the periodic table tell you about the elements on the periodic table?

How can a periodic table entry for an element tell important information about the element?
Periodic table describes chemical properties of element.It can also describe its degree of reactivity.
What does the Roman number above each column of the A group in the periodic table tell you about the electronic configuration of those elements?
Valance level
What are columns on the periodic table orginized by?
The columns tell you how many electrons the atoms have in their outer shells, which is a very essential information to understand reactions. Group 1 has 1 electron in the outer shell, group 2 has 2 electrons, etc.
How can you tell the elements have similar properties by using a periodic table?
Elements with similar properties are found in the same group or column on the periodic table. This is because they have the same number of valence electrons, which influences their chemical behavior. Elements in the same group tend to react in similar ways and have comparable physical properties.
How can you tell using the periodic table that sodium and potassium are similar?
You can tell by the location, and the fact that they are both in the same column. Elements in the same column (or group) have similar properties.
What is the benefit of organizing the periodic table in columns?
the benefit is that you can tell the atomic number atomic mass its symbol and where it is on the periodic table
Why is the periodic tables called the periodic table?
It is arranged such that similar elements with similar preferred bonding arrangements are aligned vertically. This exposes the various s, p, d, and f bonding orbitals for each successive "exterior" shell, and so appears to repeat... hence "periodic".
