How many electrons do halogens have to lose or gain to achieve a stable noble gas electron configuration?
They have to gain 1 electron. Halogens have 7 electrons in their valence shell and noble gasses have 8.
In the periodic table what group is ignored?
The Noble Gases.
What group number does the noble gasses belong to?
18
What group has the octet on the periodic table?
noble gasses
Which group or family is nonreactive on the periodic table?
Group 8. Commonly known as noble gases. Although it is true that the higher noble gases such as Neon and Helium are nonreactive, Krypton and Xenon can form compounds due to the high amounts of electron shielding experienced by its outer shell electrons. for example, Xe2Sb2F11
Do all of the noble gases have at least 3 electron shielding layers?
No, not all noble gases have at least 3 electron shielding layers. The noble gas helium (He) has only two electron shielding layers, while the remaining noble gases (Neon, Argon, Krypton, Xenon, and Radon) have three or more electron shielding layers.
Do all of the noble gasses have at least two electron shielding layers?
No. If waht is meant are the layers below the outer layer then:- He has no shielding layer (electronic configuration 1s2) Neon has only one, electronic configuration 1s2, 2s2 2p6
Is it true that all noble gases have at least three shielding layers?
No. Not sure what you mean by a shielding layer- I would take this as the filled electron shells below the "outer", highest energy layer-- He has none, Neon has one , Argon has two.
What is the name given to the gasses that have a filled outer electron?
noble
What is special about the electron configurations of all noble gasses?
The electron configuration of the noble gasses are such that the valence shell (the outer most shell of electrons) is filled up with eight electrons. the outermost shell of electrons can only fit eight and the noble gasses already have all eight.
Is it true All of the noble gases have at least three electron shielding layers?
No. He the lightest has only one 1s2. Neon is 1s2 2s2 2p6 so depending what you understand by the term layers - it either has two (complete shells) or three.
What is the electron affinity value and which elements have a zero value?
Noble gasses
How chemically active are neon?
Neon is one of the 'Noble Gasses', possessing a full outer electron shell. Chemically, they are unreactive, like all other Noble Gasses
When elements are noble gases?
All of the noble gasses have full outer electron shells - rendering them extremely nonreactive. Their electron configuration is what places them in the group on the periodic table that we have designated "noble gases".
How many electrons do halogens have to lose or gain to achieve a stable noble gas electron configuration?
They have to gain 1 electron. Halogens have 7 electrons in their valence shell and noble gasses have 8.
What happens if you mix alkali metals with noble gasses?
Nothing will happen. The noble gases are inert meaning they are non-reactive. They have filled electron clouds.
Why are noble gases chemically inactive?
The noble gasses all have a filled outer electron shell of eight electrons, except helium which has two electrons. Since their outer electron shells are filled, they are less likely to react with other atoms.
