Which is bigger mg2+ or NE?

Which is bigger mg2+ or NE?

Give two reasons why the first IE of Neon is lower than the third IE of Magnesium. Answers: -Mg2+ has a higher positive ionic charge than Ne. Mg2+ has a higher atomic number/nuclear charge (12 protons) than Ne (10 protons), so its ionic radius is smaller than Ne’s atomic radius.

Which among the following has larger size give reason for your answer I Mg or Mg 2+?

Mg, Mg2+, Al, Al3+. Atomic radii decrease across a period, cations are smaller than their parent atoms. Among isoelectronic ions, the one with the larger positive nuclear charge will have a smaller radius. Hence the largest species is Mg and the smallest one is Al3+ .

Which one between Mg and Mg+ would have more size explain?

So Mg atom will be larger as it has more electrons than Mg 2+ and thus will have larger atomic radii.

Which has larger size Na+ or mg2+?

thereby making Mg have a SMALLER atomic radius. Hence, Na+ will be larger in size.

Why does Mg2+ have a smaller radius than s2?

The number of electrons decreases by 2 in Mg2+ compared to neutral Mg atom, but the number of protons inside the nucleus remains the same. The effective nuclear charge hence increases causing the electrons to be pulled towards the nucleus, thus, smaller ionic radius.

Why is Mg2+ smaller than s2?

If one were comparing just the neutral atoms Mg and S, the S atom would be smaller as both elements are in the same period and sulfur is more to the right. However, the presence of the excess 2+ charge on Mg2+ greatly reduces its size while the presence of the excess 2- charge on S2- greatly increases its radius.

Which among i i and i has smallest size?

i+ has the smallest size.

What is the difference between Mg and Mg 2 +? Explain?

Mg differs from Mg2+ because Mg is an element/atom whereas Mg2+ is a charged ion. The latter representation is used when there is an ion of Mg present in the reaction.

Why is Mg 2+ smaller than Na+?

mg2+ would be the smaller ion this is because each ion has the same number of electrons however mg2+ has a greater number of protons and therefore is more charge dense and the outer electrons feel a greater pull from the nucleus.

Why is the size of Na+ larger than Mg2+?

Since As is placed after P, therefore its size is large because atomic size increases down the group. (vi) Na + or Mg 2+: Both the cations are isoelectronic in nature with 10 electrons each.

Why does Mg2+ have a smaller ionic radius than Li+?

So Mg2+ tends to have smaller ionic radii compared to Li+ due to higher force of attraction. Lithium is higher up in the periodic table than magnesium. Thus, it has a smaller atomic size, and therefore, a smaller ionic size.

Why does sodium have a smaller atomic size than magnesium?

Atomic size depends upon the number of electrons and effective nuclear force. Sodium has an atomic number of 11. It has only one electron left in it’s last shell.So ,there would be less nuclear force to bind it compared to Magnesium whose atomic number is 12. It has 2 electrons in last shell.

What is the atomic number of MG and Na?

The atomic number of Mg is 12 and atomic number of Na is 11. As we know atomic number is equal to number of protons in an atom and number of protons of an atom are equal to number of electrons in that atom.
