There are two possible 'noble gas' configurations:
and
Bismuth (as metaloid atom) in elemental notation: [Xe] 4f14, 5d10, 6s2 6p3
The electron configuration of beryllium is 1s22s2. The noble gas configuration is [He]2s2.
Electronic configuration of beryllium: 1s2.2s2
Be (beryllium) has 4 electrons and the noble gas notation would thus be
[He] 2s2
[Xe]4f145d106s26p3
[He] 2s2
The electron configuration of einsteinium is [Rn]5f11.7s2.
[Kr] 4d10 5s2 5p2
The Noble gas notation for Krypton can be written as [Kr] because it is a Noble gas or [Ar]4s2 3d10 4p6.
If technitium loses 7 electrons, then it will have a noble gas electronic configuration.
No, Na is sodium, an alkali metal. The noble gasses are in the far right column of the periodic table.
Electronic configuration of beryllium: 1s2.2s2
Element Be is not a noble gas it is an Alkaline Earth Metal, its full name is Beryllium
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 for Iron (Fe) is [Ar]4s2 3d6.
The noble gas notation starts for elements after helium. Helium has no noble gas notation. Its electronic configuration is 1s2
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.
Use the noble gas notation to write the electron configuration for
Beryllium has 4 electrons and is not isoelectronic with any noble gas. However Be2+ is isoelectronnic with helium.

Beryllium is a solid metal at room temperature.
