Strontium (Sr)
Sr2+ ion and krypton have he same electronic configuration
Br
Se-2 ion
Caesium.
The noble gas krypton has the same electron configuration as an ion of bromine, Br-.
Atoms are isoelectronic when they have the same electron configuration. Therefore, an anion isoelectronic to krypton is bromide. A cation isoelectronic to krypton is rubidium.
None - it would have to GAIN one.
No. No two elements have the same electron configuration.
The ions of elements nitrogen (N3-), oxygen (O2-), and fluorine (F-) will have the same electron configuration as a sodium ion (Na+), which is the same as the electron configuration of the noble gas neon.
K+ and argon have the same electron configuration
The noble gas krypton has the same electron configuration as an ion of bromine, Br-.
NO!!!! Each element has it own ground state electron configuration. Rubidium is [Kr] 5s1 Strontium is [Kr] 5s2. Notice that strontium has one MORE electron than Rubidium. The symbol [Kr] is shorthand for the full electron configuration of krypton.
Atoms are isoelectronic when they have the same electron configuration. Therefore, an anion isoelectronic to krypton is bromide. A cation isoelectronic to krypton is rubidium.
None - it would have to GAIN one.
No. No two elements have the same electron configuration.
Rubidium (Rb) has a +1 ion, will have the same electron configuration as krypton (Kr) because the +1 status means it has lost an electron. The configuration is written 1s22s22p63s23p64s23d104p6.
The ions of elements nitrogen (N3-), oxygen (O2-), and fluorine (F-) will have the same electron configuration as a sodium ion (Na+), which is the same as the electron configuration of the noble gas neon.
All have the same nuclear charge and consequently the same electron configuration.
Five electrons. Gallium has an electronic configuration of [Ar] 4s2 3d10 4p1 The outer shell can be considered full when it is the same as the noble gas in the same period, Krypton, which has the configuration [Ar] 3d10 4s2 4p6
in the same way as sodium/potassium forms an ion. Lithium has an electron configuration of 2,1 Sodium has an electron configuration of 2,8,1, Potassium has an electron configuration of 2,8,8,1 Rubidium has an electron configuration of 2,8,8,18,1 Caesium has the electron configuration of 2,8,8,18,18,1 Notice in all cases the last number is '1'. This represents the outer most electron, shell with one electron. Since it is the outer most electron and is shielded by energy shells of electrons from the nucleus, this outer most electron is not strongly held to the atom. The atom readily releases this outermost electron , and the process is called ionisation. Chemically it is represented by the formula M(g) = M^+(g) + e^- NB 'M' is an ATOM 'M^+' is an ION (Not an atom).
Iodine accepts one electron to achieve noble gas configuration. Strontium loses two electrons to achieve noble gas configuration. Nitrogen accepts three electrons to achieve noble gas configuration. Krypton already has a noble gas configuration.
