None. The Se2- ion is isoelectronic with Krypton.


What is the noble gas notation for h?

There is no boble gas notation for hydrogen and helium. The noble gas notation starts for elements after helium. The noble gas notation is a notation formed as a result of the electron configuration notation being used in conjunction with noble gases. The noble gas preceding the element in question is written then the electron configuration is continued from that point forward.


What is the noble gas notation?

"Noble gas notation" means that in writing out an electron configuration for an atom, rather than writing out the occupation of each and every orbital specifically, you instead lump all of the core electrons together and designate it with the symbol of the corresponding noble gas on the periodic table (in brackets). For example, the noble gas configuration of nitrogen is [He]2s22p3

Noble gas notation for helium?

The noble gas notation starts for elements after helium. Helium has no noble gas notation. Its electronic configuration is 1s2


What is the noble-gas notation?

The noble gas notation is a notation formed as a result of the electron configuration notation being used in conjunction with noble gases. The noble gas preceding the element in question is written then the electron configuration is continued from that point forward. The notation is shorter to write and makes it easier to identify elements. The noble gas notation starts for elements after helium. For example, the electronic configuration of carbon is 1s2 2s2 2p2, whereas its noble gas notation is [He] 2s2 2p2.

What is noble-gas notation and why is it used to write electron configuration?

The noble gas notation is a notation formed as a result of the electron configuration notation being used in conjunction with noble gases. The noble gas preceding the element in question is written then the electron configuration is continued from that point forward. The notation is shorter to write and makes it easier to identify elements. The noble gas notation starts for elements after helium. For example, the electronic configuration of carbon is 1s2 2s2 2p2, whereas its noble gas notation is [He] 2s2 2p2.


How does the noble gas configuration simplify an atom's notation?
