What else can I help you with?
What group of elements has a staple number of electrons in their outer energy level?
Group 18 elements have a stable octet.
What is the number of electrons needed for stability in the groups of the periodic table?
They r noble gases which have stable valance shell and grotp no. 18
Why is it easier for group 14 elements in the periodic table to become stable instead of transferring electrons?
Group-14 elements do not transfer electrons. They share electrons to form covalent bonds.
How many electrons does group 2 lose?
Group 2 elements lose 2 electrons to achieve a stable electron configuration.
What is different about the group 18 elements?
Group 19 elements have 8 valence electrons (obey octet rule) and are hence stable.
Why group 17 elements are strong non metals while grour 1 elements are strong metals?
Group 17 elements (halogens) are strong non-metals because they have high electronegativity and tend to gain electrons to achieve a stable electron configuration. Group 1 elements (alkali metals) are strong metals because they have low electronegativity and tend to lose electrons to achieve a stable electron configuration.
What group of elements are un reactive?
Balanced or neutral elements. They are more stable because they have a balanced number of protons and electrons.
What is the groups number for elements that have a stable number of electrons in their outer energy level?
Group 8
How many electrons do the elements of the most stable group have in their outer shells?
Elements in the most stable group of the periodic table, also known as the noble gases, have full outer shells. This means they have 2 electrons in the case of helium, and 8 electrons for all other noble gases.
How many electrons are required in the outer energy level for most elements to be stable?
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.
How to find the amount of valence electrons in an atom?
To find the amount of valence electrons in an atom, look at the group number on the periodic table. The group number tells you how many valence electrons an atom has. For example, elements in group 1 have 1 valence electron, elements in group 2 have 2 valence electrons, and so on.
Compared with Group 2A elements Group 6A elements have?
Group 6A elements have a higher electronegativity and a greater tendency to gain electrons to achieve a stable octet configuration. In contrast, Group 2A elements have a lower electronegativity and typically lose electrons to form cations.
