The elements in the same group have the same number of valence electrons and hence similar chemical and physical properties.

They all have the same number of electrons in their outer shells.
Every element in a particular group has a similar number of valence electrons.

They are in Group 15 of the periodic table, the pnictogens.
Group 16 on the periodic table has elements that form a -2 charge when they bond ionically with metals. This group contains the very common elements oxygen and sulfur. They are usually referred to simply as group 16, group 6A, the "oxygen group," or by their old-fashioned name, the chalcogens.
Group 1 Elements (elements in the first group [column]) are classed as Alkali Metals. Group 2 Elements (elements in the second group [column]) are classed as Alkaline Earth Metals. All elements not in a representative group are classed as Transition Metals. Group 3 Elements (elements in the third full group [coulumn]) are classed as Earth Metals
Copper, gold, and silver are the choices that represent a group of elements with common characteristics. All of these elements are metals.
In space, the most common elements are?
Main group or Alkali metals
Same elements of group have same valency. They possess same chemical behaviour.
The more common name for group 7 elements is the halogens
GROUPS have more in common than PERIODS. I don't know why, I just know the answer.From, Bryan Hollick
elements in a group have the same number of valence electrons. The number of shells present increases as we move down a group.
All elements in group 7 have the same no. of electrons in their outermost shells... and this no. correspondes to the group no.
they are all part of the Periodic Table:)
All the Group 14 elements has 4 electrons in its outer energy level.
