Elements in group three basically have THREE electrons in their outtermost orbitals.However, reactivity increases down the group with Thalium(Tl) being the most reactive as its outtermost electrons are further away from the nucleus.These elements react by losing 3 electrons and therefore they all have a valency of +3.
What else can I help you with?
Where are the base forming elements located in the periodic table?
On the left of the periodic table, especially group 1 and group 2 elements.
Which group is based on elements on the periodic table?
All groups in the periodic table contain chemical elements.
Where is cation on the periodic table?
Periodic table consists of elements not cations. However group 1 and group 2 elements (left side of the periodic table) are elements which will form cations easily.
In group 2 on the periodic table are they positive ions when they bond with other elements?
Elements from the group 2 of the periodic table form cations.
Region of the periodic table where most radioactive elements are found?
Group 3 of the periodic table contains many of the radioactive elements.
Why there is a group of elements in periodic table?
There is a group of elements in the periodic table as the elements with same properties are clubbed together.
What group in the periodic table of elements is gallium in?
Gallium is in group 13 of the periodic table. The other elements in this group are Boron, Aluminum, Indium, and Thallium.
Which elements occupy the same group in the periodic table?
Elements that have similar chemical properties occupy the same group on the Periodic Table.
Is a group of elements in the periodic table known as a family of elements?
Yes it is a group is a family remember that when dealing with the periodic table.
What is a group of elements in the periodic table?
A group in the periodic table is a column of elements that share similar chemical properties due to having the same number of electrons in their outer energy level. Groups are vertical columns and are numbered from 1 to 18.

Which group is based on elements on the periodic table?
All groups in the periodic table contain chemical elements.
Where is cation on the periodic table?
Periodic table consists of elements not cations. However group 1 and group 2 elements (left side of the periodic table) are elements which will form cations easily.
What group is co3 in the periodic table?
CO3 is not placed in periodic table. Only elements are arranged in periodic table.
In group 2 on the periodic table are they positive ions when they bond with other elements?
Elements from the group 2 of the periodic table form cations.
What is a groups?
group is the amount of elements in a pair or Periodic Table.
