What else can I help you with?
Which atom never form chemical bonds?
Noble gases, such as helium, neon, and argon, typically do not form chemical bonds with other atoms due to their stable electron configurations.
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.
Can noble gases combine with each other?
Noble gases rarely combine with each other or with other elements due to their stable electron configuration. These elements already have a full outer electron shell, making them very unreactive under normal conditions.
Which element has the biggest shielding?
Typically, elements with higher atomic numbers have better shielding due to more inner electron shells that shield the outer electrons from the positive charge of the nucleus. For example, noble gases like xenon or radon would have better shielding compared to elements with lower atomic numbers like lithium or carbon.
Why are neon argon and helium non-reactive?
Because they are noble gasses. All of the noble gasses have a full valence shell, meaning that they have little tendency to gain or lose electrons. Any element, which is going to be a gas, in the 18th column of the periodic table are noble, or inert.
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
What is the name given to the gasses that have a filled outer electron?
noble
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 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.
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".
Which atom never form chemical bonds?
Noble gases, such as helium, neon, and argon, typically do not form chemical bonds with other atoms due to their stable electron configurations.
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.
True or false noble gases are inert gasses?
Noble gasses are historically known as inert gasses - so true
Where can you find noble gasses in nature?
Noble gases can be found in the atmosphere; the air on Earth is partly composed of the noble gasses.
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.
