What is the bohr model of the neon element?
This is What a Neon bohr diagram looks like. This is What a Neon bohr diagram looks like. hahahahahahahahahahahahahahahahahaha -------- -----
What element has 3 energy levels and belongs to the most unreactive group?
The element is 'argon' and belongs to noble gas family.
What electron configuration is mostly likely to result in an element that is relatively inactive?
a filled highest occupied principal energy level
Do noble gasses have the maximum number of electrons in their outer energy level?
yes.they have the maximum number of electrons in their outer energy level?
Which element has the lowest ionization energy halogens metals non metals or noble gases?
Metals have the least ionization energy
What noble gas possesses 6 electrons in the 6th energy level?
This element doesn't exist.
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 element that is considered unreactive because it has a filled outer energy level is?
noble gases helium to be exact
Which element's second ionization energy level is large compared to its first ionization energy?
Cl
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.
What is the first of the noble gas family whose highest energy level consists of an octet of electrons?
Neon
Elements that have the highest first ionization energy?
Helium (He) has the highest first ionization energy. Ionization energy increase as you go across the periodic table from left to right
Who was the first member of the noble gas family whose highest energy level consists of an octet of electrons is?
Helium. It has completely filled first energy level with two electrons
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.
Is helium a chemical energy?
Helium is a nonreactive element called a noble gas.
What is the first element in the noble gases family?
helium
Is unreactive a physical or chemical property?
Helium is a noble gas, a nonreactive chemical element.
