Which of the following species are isoelectronic with Ne? Check all
that apply.
mg2+
Ca
Li+
Al3+
F-
Na+
Li
Answer
Concepts and Reason
This problem can be solved by determining the Iso-electronic neon species based on the total number of electrons within the species.
Fundamentals
Iso-electronic refers to atoms made from different elements that have the same number of electrons.
The number of electrons within any species is equal to its atomic number.
This is the atomic symbol notation:
The charge of an ion can be seen by the + or – sign in the superscript to its right.
The atomic number for magnesium is 12. It has 12 electrons. It is formed by the loss of two electrons, which is indicated by its +2 charge. The number of electrons in HTMLmedia_tag_4$ = 10.
The atomic number for calcium is 20, so it has 20 electrons.
The atomic number for lithium is 3. The
is formed when one electron is lost in it, which is indicated by its +1 charged.
has 2 electrons.
The atomic number for aluminum is 13. It has 13 electrons. The
is formed by releasing three electrons from it, which is indicated by its +3-charge.
has 10 electrons.
– The atomic number for fluorine (9) is the same as its 9 electrons. The
is formed by accepting one electron in it, which is indicated by its -1-charge. The number of electrons in
equals 10.
The atomic number for sodium is 11. It has 11 electrons. The
is formed when one electron is lost in it. This is indicated by its +1-charge.
has 10 electrons.
The atomic number for lithium is 3. It has therefore 3 electrons.
It has 10 electrons because of its atomic number, Ne.
The following species also has 10 electrons
Therefore
,
,
and
are iso-electronic with neon.
Ans:
, HTMLmedia_tag_28$ , HTMLmedia_tag_12$ , @media_tag_30$ all are iso-electronic.
Conclusion
Above is the solution for “Which of the following species are isoelectronic with Ne? Check all that apply. mg2+ Ca Li+…“. We hope that you find a good answer and gain the knowledge about this topic of science.
