What characteristics of the atomic structure of helium make it so such less reactive the hydrogen?
Helium has completely filled orbitals and is stable whereas hydrogen has one valence electron and is reactive.
34)why The naturally occurring helium atom is chemically inert?
Helium has completely filled orbitals and is hence chemically inert.
How many orbitals does technetium have?
Technetium has five electron shells.
Why is helium atomic number 2?
Helium's atomic number is 2 because it has 2 protons in its nucleus.
How many electrons shells does a helium atom have?
The electron configuration of helium is 1s2; two electrons on the first (and the single) electron shell.
How many orbitals are in helium?
one
What is helium in relation to hydrogen?
The atomic number of helium is one more than that of hydrogen. In both the elements, the electrons are filled in the 1s orbitals. Hydrogen has one electron, helium has two.
Why does helium belongs to noble gases where infact it has 2 valence electron?
Because helium has completely filled valence orbitals similar to other noble gases.
What characteristics of the atomic structure of helium make it so such less reactive the hydrogen?
Helium has completely filled orbitals and is stable whereas hydrogen has one valence electron and is reactive.
34)why The naturally occurring helium atom is chemically inert?
Helium has completely filled orbitals and is hence chemically inert.
How many electron containing orbitals does iodine have?
36
What are the different electronic orbitals?
atomic orbitals and electron orbitals
How many orbitals does technetium have?
Technetium has five electron shells.
Why is helium atomic number 2?
Helium's atomic number is 2 because it has 2 protons in its nucleus.
How many orbitals are completely filled in an atom whose electron configuration is 1s2 2s2 2p3?
Two orbitals.
How many electrons shells does a helium atom have?
The electron configuration of helium is 1s2; two electrons on the first (and the single) electron shell.
How come helium has only 2 electrons and is a member of the noble gas?
a noble gas has a full outer shell; in the case of helium the 1s shell is full making it stable and dose not want anymore electrons making it have a low reativity just like the rest of the noble gases
