Does magnesium or phosphorus have a larger atomic radius?
Atomic radius
Which has bigger atomic radius magnesium or chlorine?
Since chlorine’s 17 protons are greater than magnesium’s 12 protons, chlorine will have a greater effective nuclear charge to draw chlorine’s valence electrons closer to the nucleus and, thus, chlorine is expected to have the smaller atomic radius, while magnesium with the lower effective nuclear charge is expected to …
Which has larger radius Sulphur or chlorine?
The size of chlorine is smaller than that of sulphur and its atom needs only one electron to have noble gas electronic configuration while sulphur atom needs two electrons. Therefore, chlorine has greater attraction for electrons than sulphur. It is more electronegative than sulphur.
Which has a larger atomic radius phosphorus or chlorine?
Normally, phosphorous has a larger atomic radius compared to sulfur and sulfur has a larger atomic radius compared to chlorine. Even though you are adding electrons to the atoms, the atomic radius of phosphorus is still larger than sulfur and same thing with chlorine.
What is the atomic radius of argon larger than chlorine?
This will mean that adding a proton and electron (or going right in a period) will decrease the atomic radius. Because Argon is to the right of Chlorine and on the same period, Argon has an atomic radius less than Chlorine’s atomic radius.
How do you determine the size of an ionic radius?
Ionic radius is determined by measuring the atom in a crystal lattice. Removal of electrons results in an ion that is smaller than the parent element. Addition of electrons results in an ion that is larger than the parent atom.
Why is the ionic radius of K+ smaller than CL while both are isoelectronic?
In other words, K+ has bigger effective nuclear charge than Cl’ , which translates to a bigger net positive charge felt by the outermost electrons. This will compress the energy levels a bit and make the ionic radius smaller for the potassium cation. Therefore, the chloride anion will have the larger atomic radius.
Which is isoelectronic with CL minus?
Answer. Answer: Some of its isoelectronic species are S2″ ion (16 + 2 = 18 electrons), Cl” ion (17 + 1 = 18 electrons), K+ ion (19 ” 1 = 18 electrons), and Ca2+ ion (20 ” 2 = 18 electrons).
We say that that the chloride ion is isoelectronic with the argon atom. And we can see that the potassium ion, K+, has the same electronic configuration as the chloride ion, Cl-, and the same electronic configuration as an atom of argon, Ar. Therefore, Ar, Cl-, and K+ are said to be isoelectronic species.
Atoms and ions that have the same electron configuration are said to be isoelectronic. Examples of isoelectronic species are N3″, O2″, F”, Ne, Na+, Mg2+, and Al3+ (1s22s22p6).
Is Na+ Isoelectronic with Mg2+?
Mg2+ and Na+ both have 10 electrons hence, they are isoelectronic species.
