Atoms of the elements in a group have the same number of electrons in their outer energy shells. This gives the elements similar Chemical Propetries.
No, they do not. However, elements in the same group have the same number of valence electrons.
number of valence electron
All the atoms in group 1.
They don't. Of the main group, or representative elements, group 1 elements are the only ones whose atoms have only 1 electron in their outermost energy levels.
Atoms of these elements do not combine with other atoms, even atoms of the same element, because their valence electron shells are full.
Group 18
ns^2np^3
The atoms of Group 17 elements must gain one electron in order to become stable.
Elements in group 1 have 1 electron in their outer shell. Group 7 electrons have 7 electrons in their outer shell. This means that the group 1 element needs to give its electron to the group 7 element so that they both have full outer shells, making them stable. By a school boy in yr. 10
The group of elements that have a stable electron configuration are the noble gases.
The outer electron shells of their atoms are full, and they do not need more electrons from other atoms, so they do not easily bond.
why atoms of group 0 elements do not form ions
