Which noble gas has only two energy levels?
Helium is the noble gas that has only two energy levels in its electron configuration. Its electron configuration is 1s2, which means it has two electrons in the first and only energy level.
Which noble gas does not have eight electrons in it's highest occupied energy level?
Helium is the noble gas that does not have eight electrons in its highest occupied energy level. It only has two electrons in its outermost energy level.
What element in the noble gas family has the outside energy level that is the second electron Shell?
The noble gas with its outer energy level in the second electron shell is neon (Ne). Neon has an atomic number of 10 and a complete outer shell with 8 electrons, which makes it stable and inert. It is located in group 18 of the periodic table.
What element has 3 energy levels and belongs to the most unreactive group?
The element is 'argon' and belongs to noble gas family.
The outer energy level of a noble gas is?
The valence shell (outermost energy level) of a noble gas is filled in ... ns2 np6 electron configuration except helium where it is 1s2.
What noble gas possesses 6 electrons in the 6th energy level?
No noble gas possesses 6 electrons in the 6th energy level. Noble gases have a stable electron configuration with a full valence shell. Helium has 2 electrons in its first and only energy level, while neon has 10 electrons in its second energy level.
The noble gas distribution for the element chlorine are?
The noble gas distribution for chlorine (Cl) is 2,8,7. This means it has two electrons in the first energy level, eight electrons in the second energy level, and seven electrons in the third energy level. Chlorine achieves stability by gaining one electron to complete its outer energy level to achieve the same electron configuration as argon, a noble gas.
What element has atoms with only one completely filled principal energy level?
undiscovered...yet, but there are a few...go forward 50 years and see
An element that is considered to be unreactive because it has a filled outer energy level is?
A noble gas is considered unreactive because it has a filled outer energy level. The full outer energy level provides stability and low reactivity, as the element does not need to gain or lose electrons to achieve a stable electron configuration.
What element has a full set of electrons in their outermost energy level?
All of the noble gases, no other elements. Helium and Neon are 2 examples of a noble gas.
What is the first of the noble gas family whose highest energy level consists of an octet of electrons?
Neon
Who was the first member of the noble gas family whose highest energy level consists of an octet of electrons is?
Oh, dude, that would be helium! It's like the cool kid at the noble gas party with its full octet of electrons, just chillin' in the corner. So, yeah, helium is the first member of the noble gas family with that full octet vibe.
Why noble gases lies in eight period?
Noble gases have ns2 np6 electron configuration. They have 8 electrons in the valence shell. In addition, it is group 18 according to the modern version of periodic table.The group number of an element is equal to the number of electrons in its outermost energy level. Noble gasses has 8 electrons in that energy level. So they are in the 8th group.
Which noble gas does not have eight electrons in it's highest occupied energy level?
Helium is the noble gas that does not have eight electrons in its highest occupied energy level. It only has two electrons in its outermost energy level.
Which noble gas has only two energy levels?
Helium is the noble gas that has only two energy levels in its electron configuration. Its electron configuration is 1s2, which means it has two electrons in the first and only energy level.
What is the first element in the noble gases family?
helium
Why are some elements stable on their own while others are more stable in compound?
Some elements are stable on their own because they have a complete outer energy level. These elements are called noble gases. Hydrogen and Helium have a complete energy level with two electrons and all of the other elements are stable with eight. When an element doesn't have a complete outer energy level it is stable in a compound. This is because it is being combined with another element to complete it's energy level.
