There are 18 groups in the standard Periodic Table. These groups are arranged vertically.
Elements in the same group behave similarly because they have the same number of electrons in its outermost shell.
Group 1 has one electron, group 2 has two, ect. However, most Transition Metals in groups 3 through 13 have two electrons.
Group 1- Alkali Metals (Lithium Family)
Group 2- Alkali Earth Metals (beryllium family)
Group 3- Scandium
Group 4- Titanium
Group 5- Vanadium
Group 6- Chromium
Group 7- Manganese
Group 8- Iron
Group 9- Cobalt
Group 10- Nickel

Group 17- Halogens
Group 18- Nobel Gases

The periodic table
there are 117 elements in the pereodic table in total
These names are the names of chemical elements.
Both arrange elements in groups of elements having similar properties.
Both arrange elements in groups of elements having similar properties.
Sodium is at the extreme left and chlorine is in the next-to-rightmost cell of period 3. Most would not consider that close.

Dmitri Mendeleev decided to arrange his cards by organizing elements with similar properties into groups and leaving gaps for undiscovered elements. He then ordered the groups by increasing atomic weight, which led him to identify patterns and create the periodic table of elements.
