Magnesium has a larger atomic radius
due to a smaller effective nuclear charge
Which element has a larger atomic radius than phosphorus?
This is due to the difference in the number of protons in the nucleus which affects the effective nuclear charge
Does magnesium or phosphorus have a larger atomic radius?
Magnesium has a larger atomic radius due to a smaller effective nuclear charge
Why does phosphorus have a smaller radius than magnesium?
Phosphorus has a larger atomic radius
Does magnesium have a larger atomic radius?
Since chlorine’s 17 protons are greater than magnesium’s 12 protons, chlorine will have a greater effective nuclear charge
Why is the ionic radius of K+ smaller than CL?
In other words,
K+ has bigger effective nuclear charge
What has the smallest atomic radius?
Atomic radii vary in a predictable way across the periodic table. As can be seen in the figures below, the atomic radius increases from top to bottom in a group, and decreases from left to right across a period. Thus,
helium
is the smallest element, and francium is the largest.
Which has a larger radius S or CL?
Sulphur(S)
has the largest atomic radius
Which has a larger radius I mg or Ca II S or CL?
Calcium has
a larger atomic radius than Magnesium. If you look on the period table you will notice Magnesium atomic number is 12, while Calcium is 20. Calcium(Ca) has 4 energy level while magnesium(Mg) has 3 Energy level.
Does sodium have a larger atomic radius than oxygen?
Therefore, even though a sodium ion and an oxygen ion have the same number of electron shells and the same number of electrons, a sodium ion
is smaller
because it has a greater number of protons. Or in other words, an oxygen ion is larger because it has fewer protons.
Why does calcium have a larger atomic radius than magnesium?
Because a calcium atom has
more electrons (20)
than a magnesium atom does (12), some of its electrons will be farther from the nucleus in a higher energy level. The magnesium atom’s electrons (12e-) occupy fewer energy levels than do the electrons of the calcium atom (20e-).
Which has a larger atomic radius magnesium or aluminum?
The atomic radius of elements decreases from left to right across a period.
Is K+ bigger than Br?
Since potassium is located at the start of period 3, and bromine at the end of the same period,
potassium will have a larger atomic radius
What is bigger K+ or Ar?
K is larger than K+
because K has an extra valence shell. K+ is larger than Ar.
Which has larger size BR or BR?
Br – will have the largest atomic size
because Br- has one extra electron in its valence shell which due to its unbalanced negative charge will be repelled and hence the atomic radius
