halogens (group 17 elements)
The word "valance" is used to describe electrons in the outer-most energy level of an atom. Oxygen has six valance electrons.
Elements in the same group have the same number of valence electrons. These are the outer-shell electrons that react with other elements.
The elements which falls under the group 16 has 4 electrons in its outer p orbital...
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.
16
Group 18 elements have a stable octet.
Group seven elements have 7 electrons in their outermost energy level.
noble gases
alkaline earth metals
The word "valance" is used to describe electrons in the outer-most energy level of an atom. Oxygen has six valance electrons.
All the Group 14 elements has 4 electrons in its outer energy level.
Group 8
The noble gases is the most stable group of elements. They have their outer electron energy levels full, but the number of electrons vary according to which noble gas it is. They are group 18 on the periodic table.
there are 7 electrons in the outer energy level of group 17 elements
Elements in a group have the same number of electrons in their outer orbital.
Group 2 elements ... also called alkaline earth metals.
Elements in the same group have the same number of valence electrons. These are the outer-shell electrons that react with other elements.
