These groups are groups 3 to 12 (transition metals) containing each four chemical elements.
Group 3 has only 2 elements.
row # 1
semi conductor
Group 3 of the periodic table contains many of the radioactive elements.
Group 16 of the periodic table of the elements (chalcogens elements)
In the Periodic Table of the Elements, a column (group) contains all elements that exist with the group number of electrons in the outer energy level of an atom of that element.
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.
Group 1 in the periodic table is called the Alkali metals. It contains the elements lithium, sodium, potassium, rubidium, cesium, and francium.
Group 3, the transition elements.
Group 3 of the periodic table contains many of the radioactive elements.
Group 16 of the periodic table of the elements (chalcogens elements)
group 1 elements.
Astatine is a member of the group 17 (halogens) of the periodic table of elements.
In the Periodic Table of the Elements, a column (group) contains all elements that exist with the group number of electrons in the outer energy level of an atom of that element.
Group 18, otherwise known as the noble gases.
Group 3 through Group 13
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 the Periodic Table of the Elements, a column (group) contains all elements that exist with the group number of electrons in the outer energy level of an atom of that element.
Noble gases or group 18
This is the group 18 of the periodic table of Mendeleev.
