The element nitrogen is closest to the noble gas neon on the periodic table.
Beryllium has 4 electrons and is not isoelectronic with any noble gas. However Be2+ is isoelectronnic with helium.
Oxygen is closest to the noble gas neon (Ne) on the periodic table.
argon (atomic number 18) is the closest to calcium (atomic number 20)
The closest noble gas to fluorine is neon. Neon is located directly above fluorine on the periodic table.
Element Be is not a noble gas it is an Alkaline Earth Metal, its full name is Beryllium
The element nitrogen is closest to the noble gas neon on the periodic table.
Beryllium has 4 electrons and is not isoelectronic with any noble gas. However Be2+ is isoelectronnic with helium.
Oxygen is closest to the noble gas neon (Ne) on the periodic table.
The noble gas notation for beryllium (Be) is [He] 2s². This notation represents the electron configuration of beryllium by showing that it has the same electron configuration as helium ([He]) up to the previous noble gas before it, with two electrons in the 2s orbital.
argon (atomic number 18) is the closest to calcium (atomic number 20)
The closest noble gas to fluorine is neon. Neon is located directly above fluorine on the periodic table.
neon
This gas is krypton.
No, Be is the first element in group 2 (atom number 4) and all noble gases are in group 18 (or formerly 8)
