The simplest way to remember the groups is that it shows the number of valence electrons in an atom.
So, the correct progression is.
Group #:
1- 1 valence electron
2- 2 valence electrons
3 to 12- transition metals --> different isotopes mean different electrons
13- 3 valence electrons
14- 4 valence electrons
15- 5 " "
16- 6 " "
17- 7 " "
18- NOBLE GASES 8 valence electrons (full valence)
NOTE: charges as follows
1- +1
2- +2
3 to 12- again depends on isotope (ROMAN NUMERAL ex: Nickle II)
13- +3
14- +/- 4
15- -3
16- -2
17- -1
18- 0 NO CHARGE BECAUSE OF FULL VALENCE- stable elements

What is groups pattern for periodic table?
Groups are arranged as columns in the periodic table; the contained elements have similar properties.
How many groups of elements in periodic table?
There are 18 groups and 7 periods in the modern periodic table.
What is an arrangement of elements into groups with similar properties?
The periodic table
What organizes elements into groups based on similar properties?
periodic table of elements
How are the elements arranged?
Elements are arranged on the periodic table based on their atomic number, which is the number of protons in their nucleus. This arrangement groups elements with similar properties in columns called groups or families, while elements in the same period have the same number of electron shells.
What are groups in the periodic table?
Groups in the periodic table are vertical columns that contain elements with similar chemical properties. Elements in the same group have the same number of valence electrons, which determines their reactivity and chemical behavior. There are 18 groups in the periodic table.
What does the periodic table show you about the elements?
It groups elements with similar properties in vertical columns
What is the benefit of the periodic table?
The periodic table organizes the elements so that they are easy to find and it also puts them into groups or "families" of elements with similar traits.
How many groups columns are in the periodic table of elements?
There are 18 groups in the periodic table of elements.
How are the elements with simmiler properties desplaed in the periodic table?
Elements with similar properties are displayed in columns, called groups, on the periodic table. This arrangement allows elements with similar chemical behavior to be grouped together. Elements in the same group have the same number of valence electrons, which is the main factor determining an element's chemical properties.
