What else can I help you with?
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.
What noble gases have 3 complete outermost shell?
There are six noble gases: helium, neon, argon, krypton, xenon and radon. All have completely filled outermost shell. Helium has 2 valence electrons while the other elements have 8 valence electrons.
Which of the regions shown on the periodic table contains mostly elements that are gases at room temperature?
The region containing mostly elements that are gases at room temperature is the rightmost column, known as the noble gases or Group 18. These elements have full outer electron shells, making them stable and non-reactive, which allows them to exist as gases at room temperature.
What are some other names for Noble gases?
Another name for noble gases is inert gases.
What are the 3 lightest members of the noble gases?
Helium, neon, and argon are the three lightest members of the noble gases.
Which of the following elements is the least reactive?
Helium is least reactive element.It forms no compounds.Platinum is least reactive metal.
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 noble gases have at least three electron sheilding layers?
No. The first three noble gases (helium, neon and argon) have 1, 2 and 3 energy levels respectively.
Which would be least reactive because its last electron shell is full with 2 electrons 1.helium 2.neon 3.lithium 4 bromine?
Helium would be least reactive because its last electron shell is full with 2 electrons, giving it a stable electron configuration. Neon also has a full outer electron shell but belongs to the noble gases group. Helium is a noble gas, hence more stable and less reactive compared to lithium and bromine.
What are some other names for noble?
Noble gases are also known as, 1- inert gases 2- rare gases 3- monoatomic gases 4- zero group elements.
Are Group 8A element unreactive elements known as transition metals?
Group 8A, also known as group 18, are very non-reactive. However, they are all gases, not transition metals. Transition metals are the large family of elements in the middle of the table in between groups 2 and 13 (2A and 3A). Group 8A are the noble gases.
What noble gases have 3 complete outermost shell?
There are six noble gases: helium, neon, argon, krypton, xenon and radon. All have completely filled outermost shell. Helium has 2 valence electrons while the other elements have 8 valence electrons.

What are some other names for Noble gases?
Another name for noble gases is inert gases.
What are the 3 major categories of the elements?
Metals, non-metals and noble gases.
What are the 3 lightest members of the noble gases?
Helium, neon, and argon are the three lightest members of the noble gases.
What are 3 noble gases in the periodic table?
Helium, Neon, Argon and if another Krypton.
