[Ar]3d104s24p6
or
[Kr]
The noble gas core notation for Calcium is [Ar]4s2. This notation represents the electron configuration of Calcium by using the nearest noble gas (Argon) as a reference.
None. The Se2- ion is isoelectronic with Krypton.
Krypton (Kr) has the same Lewis structure as Se2. Both molecules have 16 valence electrons arranged in a linear structure with a single covalent bond.
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.
The noble gas notation starts for elements after helium. Helium has no noble gas notation. Its electronic configuration is 1s2
The noble gas core notation for Calcium is [Ar]4s2. This notation represents the electron configuration of Calcium by using the nearest noble gas (Argon) as a reference.
The noble gas notation for germanium is [Ar] 3d10 4s2 4p2. This notation represents the electron configuration of germanium with the argon noble gas core followed by the valence electrons in the 4s and 4p orbitals.
None. The Se2- ion is isoelectronic with Krypton.
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.
Krypton (Kr) has the same Lewis structure as Se2. Both molecules have 16 valence electrons arranged in a linear structure with a single covalent bond.
The noble gas notation starts for elements after helium. Helium has no noble gas notation. Its electronic configuration is 1s2
"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
Krypton and Selenide ion have 36 electrons and are isoelectronic
The noble gas notation for xenon is [Kr] 5s2 4d10 5p6.
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.
The noble gas notation for Berkelium (Bk) is [Rn] 5f^9 7s^2.
The noble gas notation for carbon uses neon as the previous noble gas. Carbon ([He] 2s^2 2p^2) can be written in noble gas notation as [He] 2s^2 2p^2.
